- Common questions
- How to export the baked maps?
- Is dithering applied to baked textures?
- Should I enable "Compute tangent space per fragment"?
- What are Assbin files?
- What is the bit depth of baked textures?
- What is the difference between the OpenGL and DirectX normal format?
- Why are there strange stretches in my textures after baking or exporting?
- Why is Matching by Name not working with Ambient Occlusion/Thickness?
- Why is my mesh fully black after baking?
- Common issues
- Aliasing on UV Seams
- Baker output is fully black or empty
- Baking failed with Color Map from Mesh
- Black shading cross are visible on the mesh surface
- Mesh parts bleed between each other
- Normal map has strange colorful gradients
- Normal texture looks faceted
- Seams are visible after baking a normal texture
- Seam visible on every face
- Texture baked outside of Substance software looks incorrect
Geometry Cache
When baking, meshes are pre-processed to clean them up and converted in a format compatible with the baking process. The geometry cache is a way to preserve this pre-processed geometry in a way that is fast to reload in order to avoid redoing this operation later (unless the source mesh change).
- In Substance Designer the geometry cache is created after a first bake has been executed. The cache is then kept in memory until the baker window is closed.
- In Substance Painter the geometry cache is saved as a file with the extension assbin next to the source file after the first bake.
Reusing the geometry cache speed up quite a lot the baking process, especially when tweaking the baker settings to achieve the perfect result.
