Using NodeMaterial with Unique Uniforms Per Object

Based on the information available in the Three.js documentation, I can provide some guidance on your question about using a shared NodeMaterial with unique uniforms per object.

The documentation shows that in the traditional material system, Three.js offers several material types including:

• MeshBasicMaterial
• MeshStandardMaterial
• MeshPhongMaterial
• ShaderMaterial
• RawShaderMaterial

And for shader-related utilities, Three.js provides:

• ShaderChunk
• ShaderLib
• UniformsLib
• UniformsUtils

However, the provided documentation doesn't specifically cover NodeMaterial or the new material system you're referring to.

From what we know about the traditional approach, you're correct that using ShaderMaterial with onBeforeRender() was a common way to update uniforms per object when sharing a material.

For your specific question about NodeMaterial and the new material system, I don't have specific information from the documentation provided. The NodeMaterial system might be part of a newer Three.js feature or an extension that isn't covered in the documentation chunks available to me.

If you're working with the latest Three.js features, I would recommend:

1. Checking the most recent Three.js documentation or examples specifically for NodeMaterial
2. Looking at the Three.js GitHub repository for examples of NodeMaterial usage
3. Considering whether you can adapt the traditional approach (ShaderMaterial + onBeforeRender) to your needs if the new system doesn't provide a built-in solution

If you could provide more specific information about which version of Three.js you're using or what exactly you're trying to accomplish with the NodeMaterial, I might be able to provide more targeted guidance.
