Hi,
Usually this would be something that could be set by changing the collision profile name via blueprints using the “Set Collision Profile Name” node and setting up a custom collision profile in the project settings.
However, there appears to be a bug with destructible meshes that prevents this from happening. I’ve just submitted a bug report for this (UE-7062) and used this post as a reference for the issue so that I can update here once this has been resolved.
Currently I do not know of a work around as I was only able to set the DM’s collision profile via the details panel and not able to adjust anything during runtime.
Thank you!
Tim
