Normal map issue

Maymoun

Hello guys,

 

I am working on this model and the normal looks ok inside substance painter, but it looks weird and ugly in other software’s like unreal or marmoset, I tried all the solutions I found on the internet

Switching between openGL and DirectX even before baking

switching compute tangent space per fragment on and off

triangulate the model before baking

 

and I played with the SRgb and flip y for the exported normal with no luck : (   anybody can help?

do the mesh normals match between renderers?  Substance defaults to baking with averaged normals which you might not want

Mesh normals are the same, anyway I tried many things and it worked when I exported the low poly as an FBX triangulated and the high poly as an obj, don’t know why. I knew it wasn’t a substance problem that’s why I posted this on technical section.

are you exporting the normals in the FBX?

you should export the normals in the FBX.

you should export the normals in the FBX.

Is there is any specific reason for FBX? I am working with Obj and it works fine. Anything that i need to know?

FBX files contain more information about their normals so there's less difference between what you're baking and what you're importing. 

OBJ can contain normal information but not at the same level of detail as a FBX. 

It's all about having a workflow where everything is using the same information to draw the model. Not relying on automatic processes to re-generate the information correctly later.
