Question regarding Marmoset and pre-displaced meshes (normal/tangent related)

loggie24 · Aug 2016

Hey, lately i'v been using pre-displaced meshes to preview my tileables because i find the displacement in Marmoset to cause a lot of stretching and artifacts. The thing i'v found is using mesh tangent space for xNormal (which is what i bake in) causes very weird and soft looking shadows/occlusion, while setting it to 3ds Max mostly fixes it (mesh was made in 3ds, anything to do with that?). Here are some pictures.

First one is with 3ds Max tangent (good) and second one has mikk/xNormal (bad).

This isn't a huge issue but i'm curious why. Thanks :awesome:

This does seem strange. One thing to note when using the 3DS Max tangent space, the green channel of the normal map is automatically inverted, which may be the reason you're seeing a difference here.
