The low poly is baked into the texture

ttrsk · Apr 5 2025

Hi there, I have this strange issue when details from the low poly are baked into my texture as well as the high poly details. The model is smoothed and everything seems to be normal in settings, does anybody know how to solve this problem?

Within Marmoset, can you show us the high poly and low poly meshes?

idk what happened but I just increased the map resolution to 4k and now everything is OK…

Hi! Assuming that first screenshot is a height map, I would expect it looking like that, as it captures the the difference between lowpoly and highpoly mesh. The distance to the highpoly will be larger at the center of a face, hence the facetted/ lowpoly appearance. Applying the height map, you would then need to choose the correct scale in order to get it looking right.

I'm not quite sure what the goal is here? Why not have the lowpoly match the highpoly more closely and use a normal map?

Thtank you for the explanation, I just learn how to bake properly so the goal is just to understand the process. So if I understand right the only way to fix this is increasing the number of polygons on the LP if I don’t want to bake normal map?

I think unless you have the the same mesh shape/resolution, you will always have this facetted pattern, it will just get smaller/ less noticeable as the lowpolys shape nears the one of the highpoly.

When I bake heightmaps, it's mostly baking down tiling highpoly geometry to a plane, can't say much about object-specific heightmaps.

Edit: Made a thinking mistake, the shape difference that's the deciding factor here, not resolution. But obviously with lower resolution, it's inevitable that the lowpolys shape differs from the highpoly.

Thanks, you helped me a lot:) I tried to understand what’s wrong for 3 days…
