bilgorajskim Posted October 30, 2018 Share Posted October 30, 2018 Hello everyone! Currently when I'm adding vertex attributes other than those specified in VertexBuffer (PositionKind etc.) via Mesh.setVerticesData(), it throws an error: Uncaught (in promise) Error: Invalid kind 'test' I think it would be useful to be able to add attributes of any kind. For example: I have a terrain mesh with a custom shader that takes "color" (vec3) and "moisture, temperature" (vec2) vertex attributes. It uses moisture and temperature to mix between 4 greyscale ground textures (wet and hot; dry and hot; wet and cold; dry and cold) and colorizes it. Now I have two options: - use UV2Kind, UV3Kind.. - it will work in this use case, but they are all vec2 and I may need a couple of vec3 in the future - manually create a Buffer and attach it to the mesh via mesh.setVerticesBuffer() - I'm trying to figure out how to do it. InstancedMesh is using setVerticesBuffer(): https://github.com/BabylonJS/Babylon.js/blob/c5e53c8f89b115a4c151d8dfce2e9eba12bd08b6/src/Mesh/babylon.mesh.ts#L1387 I'm unsure how to use it with a typical, non-instanced mesh. I would be very thankful for an example. I wasn't sure whether to post in Bugs or Questions, please move the thread if you consider it more a question than a bug. EDIT: I figured out a way: var vertexBuffer = new VertexBuffer( this.engine, builtMesh.groundData, "test", false, false, 2); mesh.geometry!.setVerticesBuffer(vertexBuffer); But still, wouldn't it be more convenient with setVerticesData?
