Dynamic texture + pre rendered illumination texture on different channel


is it possible to composite an animated dynamic texture that is using UV on channel 1 with a static lightning texture exported from 3d max on channel 2?
Should I use a shader to achieve that?
Could somebody help me? I have no idea on how to write a custom shader.
Thanks a lot

Using the uv2 attribute for the ligthmap does work, as you can see here:


So, if you export your file from 3dsMax with the lightmap in the channel 2, you can use the diffuseTexture (or albedoTexture if using PBR, for eg if you export to gltf/glb) for your dynamic texture.

Thanks so much, I didn’t know there was the uv2 attribute. You are my here as usual :slight_smile:
