Is it possible to cause depression in surface of a softbody by pressing down on it?

Of note, it loos like the softbody cube I'm using has almost 25,000 particles. This seems like WAY too much. Could this be part of the problem? I did not think the settings I used to create it were too egregious

Hi!

Yep, 25000 particles is *way* too much. This will not only cause your simulation to run extremely slow, but it will also be pretty much impossible to get any accurate collision detection going on because particles will be really small.

You're using voxelization as your surface sampling method, with a resolution of 64 (!!). So 64x64x64 voxels will be generated, and the ones that intersect the cube's surface will be turned into particles. Some quick math tells you that will generate 64x64x6 = 24576 particles, give or take (each face spans 64x64 voxels, and there's 6 faces). Enabling voxel render mode in the blueprint editor makes this easy to see:



Your cube mesh only has 5x5 vertices at the top face, any additional particles will be wasted so there's absolutely no reason to go above a resolution of 5 in this case, when using voxel sampling. Even the default value of 16 would be too high. Alternatively, switch to vertex sampling.
