Glb import to Unity: Materials appearing pink (URP)
I am using the open-brush-toolkit-UnitySDK-v24.0.0 to Import an Open-brush .glb.
Several non-animated materials are displayed pink while the materials with special effects are displayed correctly. The materials have been created by the SDK, but still appear pink when checking them in the Inspector.
Any ideas how I might resolve this problem? Is this related the render pipeline?
The missing materials in the screenshots are: DuctTape, Paper, Splatter, Coarse Bristles.
I have imported drawings to Unity 2019 with the latest TiltBrush SDK before and it worked just fine. Facing this problem for the first time now
