CUAShadowFixer | Fixes shadows on CUAs, while keeping baked lighting and materials intact


What does CUAShadowFixer do?
Most CustomUnityAssets are built with stock Unity shaders that don't understand VaM's shadow system, so they ignore your scene lighting and look flat. CUAShadowFixer swaps each material onto a VaM-shadow-correct equivalent that keeps the asset's baked lighting, specular, normals and emission fully intact. So correct shadows with the same overall look.

Why not use UnityAssetVamifier?
This only fixes shadows by swapping everything onto VaM's skin shader. It works, but it flattens specular and erases the baked lighting the asset shipped with. CUAShadowFixer changes only the shadow handling, so your asset still looks the way its creator intended.

About the size
This plugin includes a ~22 MB precompiled shader bundle. A VaM plugin can't build shaders at runtime, so the shadow-correct shaders are compiled ahead of time, and the bundle covers every material workflow (metallic/specular/roughness) and lightmap mode so it works on as many CUAs as possible.

Features

• Correctly receives shadows from VaM lights
• Metallic / Specular / Roughness properties remain intact
• Works on Baked Lighting environments and other renamed-Standard shaders
• Sliders to adjust smoothness, reflection intensity and over-bright surfaces
• Bonus Face-Hide tool: hide mesh faces to see into a walled room from the outside

How to use

Per CUA:

1. Add a CustomUnityAsset atom and load your asset.
2. In the Plugins tab, add CUAShadowFixer.cslist
3. Done. (it might take a few seconds for the shader to apply

Scene-wide Mode:

1. Add CUAShadowFixer.cslist to an Empty (or as a Scene or Session Plugin)
2. A new tab "Scene CUAs" appears, in which you can select CUAs in the scene to include/exclude for conversion

Face-Hide

1. Select Face-hide mode
2. Hold your cursor over a face until it lights up blue
3. Hide that face by pressing Space
