- 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
GPU Raytracing
With the support of the DXR library, it is now possible to use specific hardware to accelerate ray tracing.
Bakers casting many rays per pxiel (such as the Ambient Occlusion From Mesh) take advantage of DXR. Using this feature usually translate to an increases computation speed by a factor of 25 or more.
Enabling DXR (Hardware Requirements)
The DXR-accelerated ray tracing will automatically be enabled if the system follows these requirements:
- A compatible GPU is installed (RTX family, Titan V or Geforce 10xx)
- GPU drivers are up to date
- Windows 10 'Fall Creator' / October update (ver 1809) is installed
- To check your Windows version: click on the start menu, type 'winver' and hit the return key.
- To get the update, see : https://support.microsoft.com/en-us/help/4028685/windows-10-get-the-update
In case you are running into issues with DXR, you can disable this feature (and fall back to CPU ray tracing). To do so:
- Close the baking window
- Go into the Baker tab in the project setting in the Preferences window.
- Uncheck Enable GPU raytracing.
- Re-open the baking window and relaunch the baking process.
Rendering Modes
