Why are Impulses and forces not working on destructible components?
I've spent 2 days messing with settings. the only functions that work are apply radial force and apply radial impulse. the others get ignored. I'm especially interested in applying physics to the chunks.
If there is a way to apply linear forces / impulses please let me know what your settings and blueprint look like. also, Im not looking to apply forces on damage, but rather after and before the fracture.
For context, picture a nicely furnished room with music that is so loud that everything shakes. as things hit the floor they shatter and continue to rumble with the bass.
From your description it sounds as if you need your meshes to have more than one support depth for destruction. If you're creating your destructible in UE4 you'll only be able to have one support depth. This means that Depth 0 will be no destruction and depth 1 will be destroyed. If you use Nvidia's PhysXLabs standalone app or their plugin for 3Ds Max/Maya you can set different support layers for the destruction.
Setting up something like: Depth 0: no destruction Depth 1: slight destruction Depth 2: full destruction
These can be tweaked and set through the PhysXLabs or further tweaked in UE4 with all the depths.
The individual pieces will react to the environment and any forces and impulse as well.
You can find more information about Nvidia's destruction on their site at Developer.Nvidia.Com
If you have any questions about getting your destructible setup feel free to ask.
