Please help. I tried to create a three.WebGLArrayRenderTarget with three.FloatType but found the texture type is still three.UnsignedByteType. I thought my device didn’t support float textures, just to verify that, I c…

Hi, everyone! I was working on a custom TileMap object with a custom shader that successfully used DataTexture objects to pass the tile index and other properties to the TSL shader. Here’s an example in Three.js 0.170.…

I am interested in implementing 2D texture arrays. I’ve pretty much got the code part down (I think), but I am a little lost as far as how to create the actual images. This example: https://threejs.org/examples/webgl2\_m…

Originally did a PR for it but turns out that we can render 3D and texture arrays with MRT without any modifications to the WebGLRenderer. I made a demo to showcase Demo - https://wizgrav.github.io/three-mrt/ Code snip…

We have a raw shader material that takes in a texture array as a uniform so that we can render different textures to instances of an instanced mesh. As instance meshes go in and out of the frustrum view of the camera (or…
