Oh, I know about displacement mapping.
I'm only interested in how SP handles the height channel, because I am a beginner in SP. I know what all these do in computer graphics in general.

So in SP height is used for displacement maps? Ok that makes sense, but if you don't bake a displacement map then I guess that the height channel simply goes into the normal channel and baked into the normal map correct? Otherwise, if you don't bake a displacement map then all Height channel information is completely lost.

I'm not sure I see the difference.

Aren't the height details(/height channel) later imprinted onto the normal map?

Is height just normal without directionality (aka bump map)?

Thanks in advance.

I have the exact same problem. I add an effect, a generator or paint to a masked layer. And instead of only being applied to the masked part of the mesh, it is applied to the entire mesh's material. What am I doing wrong?

I have UE v4.23 with the SP plugin and SP 2019.3.1. When I 'Send to Substance Painter' from a mesh asset in UE4 it exports to SP, but a Unity icon is displayed, not the UE4 icon. In the project that is formed: Edit -> configuration it says OpenGL (instead of DirectX) and it doesn't have 'Compute Tangent Space Per Fragment' enabled which is a must for UE4. It seems that SP thinks that I'm transferring assets over from Unity and not UE4. Why and how do I fix this? Thanks in advance.
