Gator Material Studio 1.3.1

Bake Accuracy

• Fixed high-resolution baking so selected resolutions are now used directly instead of relying on lower-resolution working images that were later upscaled.
• Corrected padding behavior so the requested padding amount remains consistent across different bake resolutions.
• Improved tangent-space Normal baking for mirrored UV islands.
• Improved Object ID and Material ID baking when projecting from high-poly meshes.
• Position maps now use model-wide bounds so multi-material texture sets share a consistent coordinate range.
• Improved custom cage projection direction and validation.

GPU Baking

• Added GPU acceleration for high-poly Normal map projection.
• Normal, Ambient Occlusion, Bent Normal, and Thickness baking can now use tiled GPU processing up to 4096 resolution.
• GPU workloads are processed in smaller chunks to reduce peak VRAM requirements.
• CPU baking remains available as a fallback when the GPU path cannot be used.

High-Poly Workflow

• Improved high/low mesh name matching behavior.
• Failed name matches no longer silently fall back to every high-poly mesh.
• Added caching for full and name-matched high-poly BVHs.
• Improved performance when toggling high/low name matching.
• Added debounce handling when editing high/low suffixes to avoid repeated rebuilds.
• High/low name matching is now disabled by default for new projects.

Automatic Cage

• Automatic cage estimates now update when changing models or texture sets.
• Cage estimates are cached per texture set for faster switching.
• Improved fallback behavior when custom cages are cleared or rejected.

Bake Sampling

• Ambient Occlusion and Bent Normal now correctly support the full 1–32 sample range.
• Removed the previous internal 16-sample limit.

Bake Preview

• Fixed stale 3D Bake previews when selecting an unbaked map.
• Switching UDIMs now correctly refreshes the 3D baked-map preview.
• Changing maps no longer leaves the previously selected bake result displayed.

Skew Correction

• Significantly improved Skew correction editor performance on dense meshes.
• Cached UV wireframe geometry instead of rebuilding it continuously.
• Added cached UV coverage and protected-edge masks for faster painting and erasing.
• Reduced repeated texture recreation during brush movement.

Workflow and UI

• Cancelling Bake Enabled no longer incorrectly reports the operation as completed at 100%.
• Removed the misleading Sync Settings Across Sets action and clarified that Bake settings are shared across texture sets.
• Improved Bake workspace responsiveness when working with dense high-poly meshes.
