Hello, I'm working on a 3D scene in 3ds Max, and I've applied a displacement map to a cookie model to create a realistic surface. However, I'd like to attach small crumbs to the cookie's surface to make it look even more convincing. But the crumbs hardly sit on the cookie surface.

Any insights or advice on how to achieve this effect would be greatly appreciated. Thank you!

Actually im open for any scattering method (object paint, chaos scatter, multi... etc) What i am trying to achieve is something just like the attached image.

Hmm, you could copy the cookie mesh, subdivide it to a nice highres version, apply the displacement map to a displace modifier with the same settings (min/max etc., make sure it uses the same map channel as the corona displaced cookie), and scatter the crumbs on that mesh. Then, make that highres cookie non-renderable, this could work.

Not sure if Corona Scatter respects render time displacement but it's worth trying first before the workaround I posted. If not, it's a good feature request, there's certainly a lot of use cases where Scatter would need to sit on top of a rendertime-displaced mesh.

Scattering on render-time displacement is not supported yet, but you can go to the most wanted feature topic and cast your vote for it to be implemented: https://forum.corona-renderer.com/index.php?topic=37064.0
I'm not Corona Team member. Everything i say, is my personal opinion only.

Yes indeed, it would be very useful as it happens in so many situations, like scatter leaves on a displaced asphalt road etc ...
