Summary
We created a material with World Position Offset that should animate up and down and also face the camera. This works perfectly on a plane in the world. We need to use it as a custom mesh for a switch device to have client-only mesh visibility, but as soon as we add it to the switch device, the material WPO does not work at all. The material is assigned on the mesh correctly, every thing works except the WPO.
Steps to Reproduce
Create a simple WPO animated material using a Time → Sine → Lerp(alpha) A = -50 B= 50 → Make Float 3 (Z) → WPO Output. The material should hover up and down. Create a simple plane mesh using the modeling tool. Assign the material to the mesh directly. The plane should animate up and down. Assign this mesh to the switch device custom mesh.
Expected Result
The custom switch device mesh should animate up and down with respect to the WPO assigned material.
Observed Result
The mesh does not animate. The material is correctly rendered, but no WPO animation can be seen.
