    Hello everyone !

    I'm trying to spawn particles evenly on a mesh, here is my current approach :



    It works okay, but it's not perfectly even on the mesh. My understanding is that particles are divided between every triangle of the mesh, which means smaller triangles get a higher density, and bigger ones a lower density. So my question is : is there a way to get it more even ? I can always do a voxel remesh with another software, and reproject the UVs, but that's going to be really tedious for all meshes... Can the point cache bake tool help somehow ? Any direction would be appreciated.

    If that's useful, it's a pretty big system, like 500 000 - 1 500 000 particles.

    Thank you !
