I believe the main issue is that when importing to unreal you need to disable SRGB color space on the motion vector map (at least this fixed the issues for me)

@@Ben-xj9ps In his case, his motion vectors texture is completely grey which isn't right.

@@Jofoyo Good to know. I'm still new to Houdini so it was just an uneducated guess... I had visual issues initially but converting the color space fixed them all. I'll be sure to read some documentation about the motion vectors.

​@@Ben-xj9ps​Maybe you could tell me what my problem might be? When I try to load a texture into an instance material, I can't do it. I can't assign a texture by dragging and dropping, or by using the assign selected texture button in an instance material. When I try to drag a texture into an instance material, the section with the texture in the material is highlighted in red. And the assign selected texture button just doesn't do anything.

I love you too random citizen!
