Standard CC4 Materials Missing!?

Skin shows normal in CC4 even with certain textures appearing as red “X’s” but those materials/textures show up on the model in Unity3d (as well as when i export to iClone 8 from CC4). Does anyone know how I can get these textures back?

Hi,
I am not sure why this happened, but you can try to select the target material, run Reset All Textures in Modify > Shader Settings > Texture.
All the shader textures will be restored to default.
