Hello, I am trying to recreate this example in BabylonJS on a flat plane: Three.js Indexed Textures for Picking and Color But before getting to the end goal, I was wondering if this first step is possible. I was wondering if it is possible to get a pixel value of a texture based on a UV coordinate…

The pick function will provide you with the uv coordinates which you can use to map information from the texture itself. for example: https://playground.babylonjs.com/#NU4F6Y#230 - notice line 23. You can also do it with mapping on the mesh itself (using pickResult.pickedPoint) You can read about…

Thank you! BabylonJs is amazing!

The picking works for a single mesh really well, but is it possible to pick multiple meshes? I have a few quads that are overlapping and it seems to return just one.

You can use scene.multiPick in that case: https://doc.babylonjs.com/api/classes/babylon.scene#multipick

Are you implement GPUPicker？Can you share it on PG?
