Layout and fit uvs to a texture mask. Aug. 23, 2020, 3:47 p.m.


A long time ago, I believe I watch a masterclass or webinar where the presenter briefly demonstrated to layouty uvs based on a texture mask.

The mask was black and whit and had a couple of shapes, and with some sops magic, Houdini was able to layout the uvs and fit them withing the texture mask. I don't remember how it was done nor can I find the video and it's driving me crazy.

Does anyone know what I'm talking about or know of the method. If so, a share will be most appreciated. Thank you.

VDB Exterior Surface Only June 3, 2020, 6:43 p.m.

Hello Houdini community,

Does anyone know how I can VDB only the exterior mesh surfaces. For example a high-re spaceship with modeled interiors and an open cargo door.
I would like to voxelize the exterior surface only to generate a lower poly mesh without the interior geometry. I have placed a proxy cube to make the mesh water tight. While large voxel size seem to work, finer voxels still pick up the the interior props.

I have tried several solutions, techniques, an VEX post processes, but none of them seem to work the way I expect.
I an unable to share the original file since it's too large as an attachment, it has 9M triangles, sorry.

I am still new to Houdini and I may just be missing a node or parameter and I appreciate any tips or guidance. Thank you and take good care.


UVs crossing over UDIM Tiles. June 7, 2019, 11:08 a.m.

I'm experimenting with UDIM UV Tiles, but I noticed that the UVs would cross over the tiles (see image). Is this a normal behavior or am I missing a setting? If so, how do I pack the UVs on each tile without the overlap. Id like all the UVs to be contained within the UVs bounds. I'm using Houdini 17.5.229.

Thank you in advance!
