Vertex colors from Houdini to Unity 2019年1月16日12:51

Gmc, nope - nothing so far
point animations for FBX requires custom unity assets as far as I know;

Alembic for unity developer said he probably (!) gonna update the plugin soon with houdini colors support;

Another option is to create a custom node for Shader graph or Amplify so you can select a color channel -
but none of them seems enthusiastic to do it.

I still hope Houdini community can help with exporting colors properly - they have gamedev tools, probably we should ask this team to help us, so we can use standard vertex color nodes in shaders.

Oh cool, thanks!
I'll try that one and pretty sure it will work!

but I'd like to export Alembic .abc format (as I can export mesh animations)
For some reason alembic vertex color does not work directly but via channel somehow,
maybe I need to attribute promote or remap?
here is what unity alembic developer says:
https://github.com/unity3d-jp/AlembicForUnity/issues/210#issuecomment-440846343 [github.com]

for some cases new Houdini game tools are super helpful,
like I can export small solid body simulation animations via vertex shader textures,
but it's pretty limited (I can not change vertex scale, just the position)

If you can help with the Alembic SOP setup - that would be super awesome, there are tons of settings for sure,

knock knock - 2019 - it's pretty dead here =]

I hope there are more gametools coming to export vertex colors properly to Unity
a good tutorial how to pack it to alembic also works

thanks!
