You can use Hide/Show Puzzles for that.

For flat object you need to use plane reflection. For the shadows you need to use light object on your scene. Here’s a simple video that shows that all works out of the box.

It’s an issue with the engine, not the material, hope we can fix it soon, but for now just add a dummy UVMap on the mesh to fix this.

looks like it’s ok with the shader. Can you share a blender file with this piece of the mesh.

This values must be set to 0, the engine will not Respect this values.

It’s also better not to use any tools to make animation. Verge3D supports only direct animation of translate, rotate, and scale, we can’t grantee that animation made with any special tool will work properly.

Just put reflection plane or sphere lightprobe on the scene and export to the engine. It must work out of the box.

We’ve tested all materials with last 4.2 Blender and can’t reproduce the issue. Do you use last version of the engine with Blender 4.2?
