Hello everyone.

I am trying to create an HDA for Unreal. I want to use the attribute paint node but I couldn't make it work. In the Unity documentation, there is a part that explains the workflow but I couldn't find one for Unreal. Is it possible to use it in Unreal?

https://www.sidefx.com/docs/unity18.5/_painting_editing.html [www.sidefx.com] Here is the page I mentioned above.

There is a work around where you can use the Mesh Paint Mode(Shift+4) inside unreal, and paint vertex colours. Then in the HDA, convert the vertex vector data to do what you need.

Example, you can do an attribute promote to turn the @Cd from Vertices to Points. use a wrangle to convert the red to a density float attribute. Then you can use a Scatter SOP with Density. So the resulting HDA can let you paint RED to scatter objects on a static mesh in Unreal.

This would give very similar tool to the attribute paint sop.
