There are no other built-in attributes you can use with thin instances. You can create others yourself, but you will need custom shader code to handle them. For eg: > [@Thin instances, node material and custom attribute](https://forum.babylonjs.com/t/thin-instances-node-material-and-custom-attribute/11110): > > Here’s a little PG that demonstrates using a custom attribute with instances (this is more a proof of concept than anything else): [https://playground.babylonjs.com/#ZTTZJ3#1](https://playground.babylonjs.com/#ZTTZJ3#1) Instances are using the new thin instance support ([Use Thin Instances - Babylon.js Documentation](https://doc.babylonjs.com/how_to/how_to_use_thininstances)) and the custom attribute is used to vary the metallic and roughness properties of the sphere. A node material is used as the basis material, and a custom NodeMaterialBlock class is created to handle the custom attribute and i… > [@How to apply material to 6 uv maps](https://forum.babylonjs.com/t/how-to-apply-material-to-6-uv-maps/16224/2): > > No, as all thin instances are using the same material than their master mesh. If you want to use different texture parts depending on the thin instance, you will have to make a custom shader with a custom attribute to pass the u/v offset (and possibly width/height) of the texture part. See for eg: [thinInstance multiple materials](https://forum.babylonjs.com/t/thininstance-multiple-materials/13644/55) for usage of a texture atlas with thin instances. --- _[View the full topic](https://forum.babylonjs.com/t/how-many-type-of-thininstancesetbuffer/22267)._
