I figure out GPUParticleSystem has ‘VertexShaderName’ property. So i was about to replace that to my shader. But i don’t know how to pass custom uniforms and add attributes to it. Is my idea impossible? Thank you.

There are some demos in the documentation: [image] Fluid Renderer | Babylon.js Documentation Learn all about the fluid renderer component in Babylon.js. And from this thread : Babylon.js Playground Babylon.js playground is a live editor for Baby…

you can store your shader in Effect.ShaderStore, if your shader’s name is customGPU you can save: Effect.ShaderStore[‘customGPUVertexShader’] = your vertex shader Effect.SHaderStore[‘customGPUFragmentShader’] = your vertex fragment then create shaderMaterial const material = new ShaderMateria…

Then you can set your custom shadermaterial to particleSystem. Notice that ParticleSystem use instance, you have to add instance include to your code, I think you should have a look for babylon’s shader

Thank you for replying. I can’t understand well to add instance. As far as I know, when i created a material, the material should be attached like this. mesh.material = material. Am I wrong?

And i tried to do that with Solid Particle System like this: … const mesh = SPS.buildMesh() mesh.material = material …

InstanceMesh is created by meshA.createInstance(name), instance material is link to mesh.material, you can’t change material for each instance, if you want to change material for all instances (created by meshA), you can meshA.material = materialNew. Whole instances(created by meshA) will be renderr…

I think you can try it in PG, if you have a trouble with code, you can mark it , save pg and then paste it in forum. It is a fast way to find how it work wrong

If you want use your Material, you have to set useModelMaterial true, [image] if you want to buildMesh(), you can: const mesh = SPS.buildMesh() mesh.material = material, When sps digest particle, sps will use your material, if useModelMaterial false, it will create a default material [image…

Thank you Moriy. I’m coding with PG to create example what i want. Please wait for me.

Done. Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes Is it possible like this way with GPUParticleSystem?
