Hi, I want to apply envMap on instancedBufferGeometry but not working… based on this example: https://codepen.io/kabukimono/pen/eYpaNKK?editors=0010 I made my geometry like below, const COUNT = 100 const particleGeo = new THREE.SphereGeometry(0.2, 32); const geometry = new THREE.InstancedBu…

I made the following change, just to check using a standard material. It doesn’t work if I use MeshStandardMaterial. It only works when using MeshBasicMaterial. Hopefully, this provides a clue. const materialx = new THREE.MeshBasicMaterial({ color: "white" }); materialx.envMap = envMap; con…

Hi Thanks for the reply! I supposed to use MeshStandardMaterial for all instances to get reflected from environments and lights together and also want to use metalness, roughness as well. Do you know why it doesn’t work on MeshStandardMaterial?? At this moment in my CodePen, all the instances are…

I checked a bit later but really thank you so much for this much effort into my problem. you solved my problem so easily by using .onbeforecompile! not sure why I tried the weird way. even if I’m so happy enough for this answer, I’m just curious about why it is not working with MeshStandardMateri…

Think about it using this mental model. The shaders that are shipped with three.js come with a lot of “features” built-in. These “features” are chunks of shader code. Standard has “features” not in basic. But in some cases, basic has features not in standard (like instanced mesh support). When …

that makes sense! I understand now thank you And appreciate for this good website. I will go for this!

For unknown reason, you create MeshStandardMaterial via ShaderMaterial. Doubtful pleasure.
If you want to modify MeshStandardMaterial, modify it with .onBeforeCompile:
