I haven't tried the latest branch yet, but mesh self-intersection can also happen in the standalone Instant Meshes application in some circumstances.

Disabling “pure quad mesh” (the quad dominant flag that Luiz mentions) fixes it, but at the expense of allowing N-gons.

# Build Instant Meshes Commandline
cmd = [instant_meshes]
cmd.append("-D")
cmd.append("-f")
cmd.append(numPolys)
cmd.append("-o")
cmd.append(out_path)    
cmd.append(in_path)

Hey guys,

Can someone send me one of those files that are erroring out? I haven't been able to reproduce it.

You can try hitting Clear Cache and seeing if the problem goes away. I'm wondering if that's an issue with loading the OBJs back in from IM or something that they're generating.

I've also pushed an update to the Development branch that adds the Quad Dominant option and control over the Crease Angle.

Hi!

I am attaching the bugged file. I have updated the tool to the latest one but it didn't help

Cheers!

Tomasz

Has the overlap issue been fixed ? Instant Meshes is already part of Modo but I'd love to paint areas that I want to re-topologize manually as so those areas are deleted automatically for edge flow etc ?

I know you can paint a direction flow in the stand alone application.
Would it be possible to use Houdini attributes to act as those guides, so you can use the comb node for more control?

Unfortunately, this HDA is at the mercy of the commandline options exposed by the instant meshes tool. The curve/painting tools are all interactive parts of the GUI, so we can't currently add them in.

I'm o.d.d.

Interesting. Do you have a reference (link) somewhere that they included/licensed InstantMeshes in Modo?

Doesn't seem to be listed in the credits, but references can be found elsewhere:

04 July 2017

Since version 10.2, Modo uses our Instant Meshes algorithm to implement its automatic retopology feature! The Foundry just released an interview with Wenzel Jakob [www.foundry.com] (PDF) about this technique and other recent projects in this area.

Hey everybody,

I put together a quick little SOP that lets you call instant meshes from inside Houdini.

For those that don't know, instant meshes is a really cool open source software that does a great job with quad remeshing.

https://github.com/wjakob/instant-meshes [github.com]

Looks great! Will definitely have a look at instant meshes

No longer an issue for me.

How did you solve it? And you are on Windows right?

Hello, has anybody ever experienced this issue of instameshes producing holes in the geometry?
Cheers

Yeah, it has a hard time with thin edges… You can try increasing your resolution, sometimes it helps

It would be better to make Core-node instead bridge. I made it for Fabric Engine years earlier, it was easy https://vimeo.com/199342334 [vimeo.com]
