High poly to Low poly bake

GhostMasaki

Hey there, i'm trying to bake a high-to-low poly model but I'm having some issues,
I'm using this high model as a test:

first I tried to bake with Substance Painter and here's the result:


then I tried to use Marmoset toolbag 4 and I got this result:


I think its an issue with the normals, I tried to export as obj and fbx, flip, and reorient normals but nothing changed.
all the tutorials out there are straightforward and they don't have to do anything special for this to work, I hope someone can help me figure it out.
thanks!

Hi! I don't quite understand what's your high poly (first image?) and what's your low poly. If you have a separate body and handle mesh use match by name in Painter or Bake Groups in Toolbag to avoid close-by meshes projecting onto each other.

Generally, I'd make sure to check the applications' documentation and read about baking in general (Toolbag Baking Tut, Polycount Wiki Texture Baking)

Hello, here's something close to what I'm trying to achieve: https://youtu.be/oEv4DkUgLR0?si=ylqvj0f-P4K9b0d-

and my low poly is a simple box:

toolbag is likely set to bake with an averaged cage, if you ramp up the skew mapping you should get the same results as painter, might cause seams on the ... wel uv seams tho

Hi! To get a convincing, protruding handle, I would use actual geometry.

If you want to bake a handle onto a flat surface, as Neox already wrote, account for skewing due to an average normal cage (or add during texturing, or in engine as decal). When using floaters, shape them accordingly, as sharp corners won't show up in the normal map. I think many problems can be accounted for in the design of a prop too (inset handles?).

Best way to learn, imo, is to make an actual prop.

I'm limited to a specific design, that's why I can't add geometry to the shape.
this was very helpful, thank you so much.
I got the result I wanted by using skewing and following the tips in this video: https://www.youtube.com/watch?v=8W7txa9ltBw

if you want that protruding handle or something be in normal map only  why not just paint it in  SPainter   or any texture painting soft .

yeah i did that already, i just wanted to see how far I can go with high-low poly surfaces
