    Is there any easy way of combining the ui canvas group alpha value to all the 3D elements than a UI can have attached (particles, 3d models,...)?

    I don't think so.. I'm pretty sure UI components (such as Canvas and CanvasGroup) can only affect the rendering of UI components that use Canvas Renderers. Because MeshRenderers and ParticleSystems do not use CanvasRenderers, I'm pretty sure they cannot use values from an CanvasGroup unless you write a script that copies the alpha value of the CanvasGroup to the color value of your Renderer's material.

    If you're a graphics wizard, it may be that CanvasGroups set uniform values that can be accessed in a shader, but I'm not sure.

    I was thinking in having a specific Canvas Group that could track all of this uniforms changes but I don't know if this is the correct solution
