we're trying to export a maya geo-cached geo (multiple pieces of geo) and houdini is completely crashing on import.
we just updated our export plugins to the latest 2010 version but I'm not sure
what houdini is using.. which FBX version should we be exporting in
to get stuff into houdini properly ?
thanks

Anyone know of a script that would allow you to export a whole scene of geometry containers to either:
a single Obj file with each container as group in the obj file
or
multiple obj files, one for each container
a single Obj file with each container as group in the obj file
or
multiple obj files, one for each container

I just installed Apprentice on a new machine (it runs great).
However, when I tried to render using mantra, parts of the scene disappear. All but the ground object.
Now my scene is very big with many, many polygons etc. I was thinking maybe now there is a limitation on the number of polygons or something?
This file rendered just fine on Houdini 9.x and 10.x on mac. I just now am having issues on my linux box with the newest release.
Any help is appreciated.

Hello,
I am trying to render a geo with the following script:
hou.setFrame(int(hou.expandString('$RFEND')))
Valid Frame Range is set to Render Any Frame.
I can see Houdini set the time line to the last frame, but what it renders is the frame that was selected before hitting the render button.
Any ideas?
thanks
ps.
same thing happens when using hscript with:
fcure $RFEND

it calls my atention that in other post, a crashing problem on mac was solved only by updating the software version in this thread.
http://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=17820 [sidefx.com]
does it means that there are specific versions of houdini that works better with every o.s. or service pack in windows?
so, if i dont have a specific service pack in windows xp it could be a cause of crash?
is there any table or something to see what version of houdini is more compatible with each o.s. or windows service pack?

Hello everybody,
We are making a war scene.We are primarily making use of houdini.Could anyone tell how to create debris of building pieces lying in the ground.We are planning to make it scattered and as a digital asset.We would be using these debris pieces so that a war scene kinda mood is achieved
As of now i have thought to use fracture a box or a sphere and make it collide and fall and after it gets to a rested position.I am planning to apply initial states..
Is that a better idea to achieve that.Also tell me whether can i change the pieces of the crack after in the digital asset,
Many thanks

Hi there,
Just finished a little demo.
The focus on this project was image planes.
The challenge for me was to find a way to export the multiple passes to one exr file and in one rendering.
The main problem in this was the separation of the shadows.
You can simply resolve this with takes but then you don’t have the one file and the one rendering.
So as many as you know and discussed the way to go is illuminance loop.
Screenshots of the shader are in attachment.
I used the following shader exports.
RGBA
Surface color
Alpha
Mask
Mask.red: Diffuse
Mask.green: Occlusion
Mask.blue: Shadows
Links:
Demo reel: http://vimeo.com/8995047 [vimeo.com]
Making of: http://vimeo.com/8995283 [vimeo.com]
Thanks to all here and at odforce who helped me understand the illuminance loop.
Cheers,
Claudio

Hello all,
I piping a mantra render node into the render node of img.
There is the limitation of just being able to use pic. I have apprentice HD which renders out .picnc.
Is it not possible to use this node at all? Or is there some kind of work around?
Cheers
Rainer

Technical Discussion » How would you import multiple attributes into vex..
-
- IsStuff
- 238 posts

I have a vop sop and i am looking to import a list of int point
attributes such as…
closest_pt_curve_0
closest_pt_curve_1
closest_pt_curve_2
closest_pt_curve_3
closest_pt_curve_4
closest_pt_curve_?
each attribute is needed to be tested against in a loop so if there are 18 attributes the first loop will need closest_pt_curve_0 and the last closest_pt_curve_17. the documentation is a bit lite on for vex arrays. I would probably would need to concatenate “closest_pt_curve_” with a number too which i am not confident will work ether?
i can turn what ever vex code into a VOP node later but for now i need some documentation or even someone to propose an answer my guess in pseudo code (python meets vex)
def importAttribNum( stem=“closest_pt_curve_”, attribNum=0):
int data = 0
import(stem + attribNum , data, 0)
return data
any ideas
