Hi Mickaëlle,
This is expected in UE 5.7. Unfortunately, Particle Color and other material-related bindings are still not available in that version (or even in the latest source build, from what I can see). Compare the standard bindings on the Details Tab of the Mesh Renderer and Nanite Renderer:
[Image Removed] [Image Removed]Note that binding Niagara attributes to Material Parameters is also not supported on any renderer (Sprite/Mesh/Nanite). The UI below allows setting constant values only:

[Image Removed]Let me know if this works for you. By the way, if you find that the Nanite Renderer is still not suitable for your needs, note that some people have come up with workarounds. Here’s an interesting example.
Best regards,
Vitor
