The default material key is 0,1,2 and clipping. But I need more materials, how do I create materials and use the material key

Hi @a87645507,

Just to clarify, you’re trying to add more than three raster overlays to your tileset, is that correct?

If so, you’d have to create a copy of the CesiumDefaultTilesetShader. If you look at the shader graph, you’ll see nodes that correspond to each raster overlay. For example, raster overlay 0 corresponds to:

  • overlayTranslationAndScale_0
  • overlayTexture_0
  • overlayTextureCoordinateIndex_0

So, make a copy of all the nodes used for a single raster overlay. Then change the index so that it increments. For example, your next rasteroverlay will be index 3, so you need to rename nodes to overlayTexture_3.

Then, create a copy of CesiumDefaultTilesetMaterial and set the shader to your modified shader copy. Put this material on the tileset, then assign the material key to your desired overlay.

I hope this helps! Let us know how it goes.

Thank you. I’ll try
