scatter not projecting on mesh

[MaxMph]

hi so i have this mesh i made in blender. for some reason scatter just wont work on it. I have been trying to fix it for ages and i just cant figure it out. i think it might have something do do with size or face count or something but i am not really sure. her is a screenshot (i have delete on miss which is why there isn't anything there).

Sorry for the late reply.

1. Does your terrain actually have a collider?
2. Is the collider layer matches the layer in the modifier (by default, everything is on layer 1 but it might be different in your case)
3. If you disable the Project on colliders modifiers, does the default cubes appear? if they don't it's probably linked to that gltf import error in the console, try with one of your own scenes
