Mirrored object baking error

L00KI · Nov 2021

Hello everyone!

I have weird artifacts when baking in Marmo mirrored object, especially around seam. Did anyone have similar problem and maybe could help?
Meshes were made in blender. My HP doesn't have UV mapping and double geometry or hidden faces, my LP have standard Mirror modifier

Blender v 2.93.6
Marmoset 4.0.2

Yeah, there are a few things you can try:

Make sure the entire mesh is there, if it's only half of the mesh you'll get seams as shown in the video
Offset the mirrored UVs one unit outside of the 0-1 space
Alternatively, you can try enabling Fix Mirrored Tangents in the bake object - with this option on you shouldn't need to offset the UVs
