Hi,
I try to get a flip fluid sim from houdini to Unreal using the provided SideFxLabs VAT_Fluid material in Unreal.
I'm running
- Houdini 18.5.462
- UE 4.26.1
- Vertex ROP 2.1 as discussed here https://www.sidefx.com/forum/topic/74083/ [www.sidefx.com]
Unfortunately above thread only has very few entries regarding flip fluid and how to use it with the VAT_Fluid material.
I do get the texture animation partially applied to the fbx, but with broken shading and jittering triangles.
My main issue right seems to be that the position2 and normal map slots are not showing up when I create a material instance, so I don't know if those are actually getting used, even if I hardcode the textures in the original material.
I tried recreating the material in a bunch of different ways, but I guess I don't know how the VAT Material Function reads in parameters and how it passes those on to material instances.
So, maybe it is fixable by just updating the shader network, or it might be buggy?
Do people out there get 4 texture slots (color, position, position2, normal) when instancing the vanilla M_VAT_FLuid from the Side Effects_Labs_Content for UE4?
Many Thx+Cheers!
