Hi, sorry for the delaying in responding. Please could you clarify which files are missing? Thanks!

The files are made by unreal engine 5.3, and its not possibile to use them on UE 5, 5.1, 5.2 because Epic Games dosent let you downgrade Uassets. is it possibile to get at least the material in the oldest format soo can be used from all the unreal engine 5 versions?

what did you do regarding this issue?
+ I can't make [PE_Heightfield layers to ID] to work in the part 6 of the tutorial, it is only black
mosesthecgartist 9 ヶ月, 2 週間 前 |
same issue. have you fixed this issue?
xfdang 8 ヶ月, 2 週間 前 |
In my case it only happend in the first layer, because its index is 0 and corresponding id value is 0 no matter how many layers you have out there. For example you have 3 layers Rock(0), Grass(1), Sand(2), say we are using a 8bit int, so their id value will be 0, 1/255.0, 2/255.0, the Rock layer will be missing because the default value is also 0, override 0 witn 0 make no sense.
I fixed it by modifying [volumewrangle1] node of [PE_Heightfield layers to ID], add 1 offset to the index variable(line 2 form "int index = chi("index") ;" to "int index = chi("index") + 1;"). It still has some issue and may need change some following nodes but at least the output image seems correct.
Hope George can fix it in a better way.

Really awesome tutorial with very nice optimization in mind. I learned a lot and will definitely utilize the technique in my own open world project.
It would be great if we can learn more about the Houdini 20 spline feature and what it's capable of in Unreal!

I think we can open the hda and find the problem with that import method.
But I have another blocker, the color shader in unreal 5.3 is not working at all, it keeps that squares textures and never shows the masks ;<, I will continue checking what is happening here, anybody have the same problem ?
mac3designer 1 年 前 |
It's because if you follow the package setup, and change the other project name, some assets will cause this error, after only downloading the project files and using Unreal, and Houdini, this doesn't happen, I believe the good practice is to remove/pegasus in assets and use dynamic paths and save the digital assets for use in any package project, but this is only a lessons to learn about pipeline for create worlds don't for create from scratch, but good idea is share the files per modules, for don't give the user lost in the tutorial :D.

Amazing series. I found though that when adding 7 or more id layers they break and some bits are not selectable in the material layers, defaulting to the background material. Anyone else come across this and found a way to fix?
jmtcgi 1 年 前 |
@zakkatara To use more than 7 layers you have to switch from Round to Ceil inside the "MLB_PE_Landscape". You can find it at the "correct bit" section
asbird2009 1 年 前 |
I needed to switch from round to ceil for 7 layers, but then I added an 8th layer and had to switch back to round.
GeorgeHulm 1 年 前 |
The default settings on the material instance have been updated and the project files have been re-uploaded.
I'm sorry about the problems everyone!
A couple of important notes on things poorly explained in the series:
- The "number of idmap layers" parameter must be set to the number of layers encoded to the idmap.
-The "bit" must be selected in the blend asset
-The "texture atlas index" is selected in the layer asset.
- The material assumes a terrain of resolution 2017, otherwise, users will need to modify the resolution and terrain size parameter to compensate.
prerrro 1 年 前 |
Thank you !!! Awesome tutorial indeed, I'v already started to learn material layers :) but this shader is incredible, again, thank you very much!
GeorgeHulm 1 年 前 |
It seems my latest update introduced a new problem. You need to make sure that you change the compression setting of the "TA_Masks" and "TA_Normals", to be "masks" and "normal" respectively.

Now I come with my own issues sadly aha, I've processed all along and now I found myself a bit stuck as the master material landscape provides a bug that a TextureSample is missing input. Can't figure out alone what should be sourced in. Atm the material seems not usable to me.
Also tried to reimport files (materials content folder)
Here is a screen of the issue :

The only thing that I've changed during the tutorials was the name of the envVar Pegasus projects to fit mine, Overwrited where it was needed ofc.
Am I doing smthng wrong ?

Some trees it's floating, https://i.imgur.com/dBZDhfA.png

I have the same issue, that's because the landscape size issue. I set heightfield in Houdini 4000 x 4000 with resolution 4336 x 4336.
The resolution 4334 is due to Unreal, it set its Landscape to a specific size.
And because of this (4000 vs 4336), Houdini Engine has to use the scale in Unreal to match the size. So my scale in the Landscape was not a even number.
And that's the reason why it causes the position offset (slightly offset from houdini).
To solve this, just make sure the size is the same as the resolution, or can be evenly scaled. In my case I changed the 4000 size to 4336 and the scale in Unreal become 100 for both x and y. And it works.
papamadoo 1 年 前 |
I had the same problem, Since they didnt use it in the video I didnt care at first, but there is different specific value for the landcape optimisation in both unreal/unity.
I made some test because I had also the 100x 100y on axis, so this bound to the resolution specificly. I try the 256 to 2048 got the offset. But when I switched to the Recommended Landscape size https://docs.unrealengine.com/5.0/en-US/landscape-technical-guide-in-unreal-engine/. I got no more offset and the resolution is the same as houdini.

hello,
On the video 7 | Material Setup, starting from 2 minutes 29 seconds, you talk about overwriting the cache at 2 minutes 30 seconds, saying "if you remember." However, I don't see which part of the tutorial you are referring to at that moment. As a result, I'm currently stuck, and I don't understand where I missed the part that imports the base heightfield into Unreal.
Thanks for your help.

Hi,
Did you get the reason and how to correct this? I am having similar issue
mac3designer 1 年 前 |
I will see the idmap lessons, by who is correct?
bit=0
material selection=0
or
bit=0
material selection=1
because I found in the code in layers for id, and has numberkeys-1 and texture atlas layer return ever 6, but we have 7 now, but never change the number of layers in the field, and I my case, don't works grass inside of moss layer, I try any combinations of bit and material select, remove everything, but don't works.
rcyl4 9 ヶ月, 1 週間 前 |
I think it is caused by Houdini writing the idmap starting from 1, and reading the idmap in Unreal starting from zero. So we need to subtract one
leKryuk 1 年 前 |
Hello,
I've identified an issue with the PE_Load_Landscape node related to reloading or updating "Pegasus_Landscape_Layer_2_Manual_Edits.bgeo.sc" files. My Houdini version is 20.0.547.
Here's how it currently functions:
1. In the parameter interface of the PE_Load_Landscape node, you set the Directory to your landscape files.
2. You load files from this directory.
The problem arises when updating existing files with new information. For instance, if you modify your procedural details on the landscape, overwriting the "Pegasus_Landscape_Layer_2_Manual_Edits.bgeo.sc" file, pressing the "Reload" / "Reload Geometry" button in Houdini or Unreal doesn't result in any changes.
The root cause of this issue lies in the PE_Load_Landscape node, which employs three "File" nodes for loading three landscape files: Source, Manual Edits, and Procedural Details. The problem is that the "Reload" / "Reload Geometry" buttons only work for "file3," which is responsible for reloading the Source landscape file.
To resolve this, we need to update the functionality of the PE_Load_Landscape node to ensure that the "Reload" / "Reload Geometry" buttons also work for the "file2" and "file4" nodes, responsible for Manual Edits and Procedural Details, respectively. This will ensure that changes made to these files are reflected when reloading in Houdini or Unreal.
Let me know if you have any questions or if further clarification is needed.
Igrom 9 ヶ月, 3 週間 前 |
What solution did you find, I am also facing the same problem with updating the landscape. Only changing the node allows to update the information, but the "Reload" button does not work as you described above.

asbird2009 1 年 前 |
I don't know if this will help what you're referring to, but I was having bad visuals as well. Mine seemed very dark. I saw in one of the videos he went out of the geometry node and had some light nodes labeled sunlight. I couldn't get that to work.
I ended up changing the lights settings by pressing 'D' and going to the Lights tab. In the Headlight section I increased the Intensity and it seemed to brighten everything up.
Hope this helps.

In Lesson 6, the Layers to ID node is broken. It fails on line 8 of the menu parameter node definition for "id_layer", `dict = geo.dictAttribValue("id")`. It cannot find the parameter called "id" even though that parameter exists.

Interestingly, this error disappears if I reimport the package. The new problem is it appears black on the landscape instead of showing the mask. The project files do the same.

Hi, I've completed part 7 and have two questions:
Is it possible to use ID masks as a base for blend layers in Unreal Landscape? I would like the option to paint my landscape in Unreal on top of a predefined bake from Houdini.
There is no information about how the manual landscape was created. I assume it is just a flat heightfield? This becomes relevant when I try to flatten my landscape inside Unreal. I find it challenging because the procedural and source layers still contribute to hills. Have I missed something? Should it work this way?
Josh Short 11 ヶ月, 3 週間 前 |
Did you have any luck packaging the Unreal project with the Nanite landscape? It doesn't work for me - no tessellation and lots of weird scaling triangles with gaps. Working fine in the editor!

Hi,
if I want to import my file cache files of my terrain into UE like described in section 2 (pipeline overview) it does not find my bgeo.sc file. They show up in my file explorer but not if I search in the >load landscape node inside of neither unreal nor Houdini.
Does that mean I can only use the Pegasus file cache terrain and not the one I created throughout Ian's previous tutorial (my landscape HDA file cache) or am I missing something? (loading my asset into UE just like Ian did in his last section of landscape creation worked fine)
I have bypassed this problem with importing my own file cache files inside of Houdini and went on until section 7, but it seems like it is rather important to use >load landscape in terms of communication between UE and Houdini.
Would love to hear your suggestions, thank you!!

After I check Nanite landscape (last lesson) - the landscape material stops to work. It visualizes just one layer (for some reason -3rd, the sand) over the whole landscape.
After unchecking Nanite - everything becomes good.
I've done everything shown in the video - changer .ini and build data. Any ideas on how to fix it?
jaroslav.holy 11 ヶ月, 2 週間 前 |
Great tutorial. I've learned a lot.
You decision was to not feature rivers and water bodies. That's a shame because rivers and lakes make such a big difference in landscape and the erosion tool does amazing job simulating those rivers and lakes. I am trying to figure out how to export those rivers to game engine but I can't figure it out. Could you point me in the right direction please.
I managed to carve river bed using water mask and some scripting and now I am trying to convert original water layer to mesh but it's difficult to smooth it out and fit it into the riverbed heightfield. I appreciate any advice.

Hi, I've been using the pe_advect_heightfield_points in my environment and found that when rolling the points towards the assigned mask the points start to float. After doing some light digging into the subnetwork of the node I noticed the 2 point wrangle notes that does the advecting(attribwrangle1 + attribwrangle3) only modifies @P.x and @P.z, there is no Y component mentioned anywhere in the code. I'm highly suspecting that is the cause of the floating. Just thought I'd let you know.
For now I have linked a ray node immediately after the pe_advect_heightfield_points with my working heightfield assigned to the second input and that sticks the points back to the ground.

Preload the meshes you are using into Unreal's memory by either dropping them onto the landscape temporarily or fully open them in a viewer. Seems that processing the meshes not yet in memory breaks UE. At least, that's what fixed it for me.

These are fantastic tutorials and I'm grateful they are available. At a glance, Houdini offers so many workflow optimizations and ability to easily iterate, I'm really excited to try it all out.
I am finding (primarily as I arrive at this tutorial) that following along through the different tutorials in this series to be.. well.. a mess; duplicates everywhere, and many hda loading errors that result in an inability to follow along. (due to inexperience, I'm sure).
I'm now to the point that I'm going to have to uninstall Houdini, delete all the files and folders I've created following along, and reinstalling fresh. Is the somewhere I can get more information on how the Houdini workflow file system is intended to work? Like, WHEN hda's load, WHY they load, and the DIFFERENT ways to handle global vs project level?
I watched the workflow tutorial, but it doesn't really go into NOT using your system drive and/or a single default location when dealing with - more specifically, - hdas, projects, and hip files; which made this exponentially more difficult for me.
I went looking for - but didn't find - just one download for this series that would contain all of the files needed for the series instead of the bits and pieces that we get from each tutorial that are seemingly inconsistent? I was hoping this might solve most of these issues so I could complete the series and make a determination. Does such a thing exist?
Thanks for any input/feedback/assistance!

FYI (someone may have already mentioned this and I missed it): Enabling the grass in lesson 13 does not work with the "updated" files. The only way you'll see the grass is up the layers bit by 1 in the landscape material; which ofc breaks the textures.
A note on the Woodland Advect points - these procedures push the trees back into the scree, I had to add the scree layer into the last advect's mask to "mostly" stop it. I also had to add in a snap_to_terrain attribute wrangle after the last advect (Thanks to Indie-Pixel for sharing this!) because there were a lot of points floating and under the landscape (no idea why, still learning). This additionally fixed a lot of the "floating" trees, but not all.
The attribute_wrangle:
vector samplepos = set(@P.x, 0, @P.z);
int primid = nametoprim(1, "height");
float height = volumesample(1, primid, samplepos);
@P.y = height;
The implementation of the "woodlands" is great for learning to create scatters, UE texture import masks, and splat maps, but much of the way it's done here, doesn't work very well with UE (a lot needs updated). Moreover if your not using tessellation you might use VTs instead - save even more shader complexity.
A possible "floating asset" solution is just just create reference actors for UE and let UE spawn and place assets on location references and on-the-ground properly - some trees, for instance, still float off the ground even after the snap_to_terrain, probably because of the 200% UE scaling but idk.
Hope that helps!

After I loaded the landscape in UE and switched the mode to updating exist, the landscape disappear in the viewport and the hda started loading again, and it finally loaded an empty landscape. QAQ

It appears that PE Rolldown Heightfield uses an "embedded" definition and not a dedicated OTL/HDA so Post Processing the paths to snap them to terrain won't work unless you find a work around such as raycasting. Any chance of getting this updated?

Will this be integrated with the Unity plugin?
