Hi! What could go wrong with the scenario below? I have a code that works like this: Load a mesh Create new StandardMaterial and apply it to mesh I have about 100 meshes and each have unique diffureTexture. Performance is good. Then, the next version is this: Load a mesh Create new CustomMa…

[image] JSa: I am wondering how StandardMaterial handles this “out-of-the-box” without any performance hit? You will still have some perf hit because there’s a creation of a material each frame, so some GC will kick in at some times. It’s not as bad as with a CustomMaterial because the Standa…

It should definitely be possible to cache the shader and reuse the effect. Could you provide a quick repro in the playground I am worried we might have a cache issue ?

Maybe that can help: [image] Multiple materials with same shader settings Questions It can’t really be optimized as you really need 50 different materials here. Because you are using a CustomMaterial, it will also create 50 shaders (effects), even if the code is the same.…

Here you go ( using my existing test-bench, it seems to catch multitude of bugs easily :smiley: ): CustomMaterial, this uses 50% of CPU all the time and even FPS drops to 30fps when zooming: https://playground.babylonjs.com/#U2KKMK#167 Same with StandardMaterial, no problems here: https://playgr…

You should not create new materials continously but create a pool beforehands and get one from it when needed: https://playground.babylonjs.com/#U2KKMK#170

Hmm… I am wondering how StandardMaterial handles this “out-of-the-box” without any performance hit? For CustomMaterial to be as effective should it somehow cache the internal shaders globally instead of always recompiling them? I feel uncomfortable that just changing the material color would lead i…

[image] Evgeni_Popov: You can do something like that, but it is not really supported as the _uniformBuffer variable is not exposed: https://playground.babylonjs.com/#U2KKMK#177 Thank you! :slight_smile: This is just what I am looking for! I would be very happy to see this part of exposed API…
