Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Unbreakable chunks of the DestructibleMesh

Hi there, I've tested destructible mesh created from NVIDIA PhysX Lab, and there is a problem to fracture the destructible mesh which has more than 1 depth .

I've created destructible mesh asset using PhysXLab with the 'Max Depth' property as 2. alt text

At the UE4, I've configured the destructible mesh like below.

DM settings

After then, I shoot the weapon carefully to fracture only small parts. They broken well, but some chunks which was not fractured more than depth 1 at the first shot, became unbreakable chunks.

alt text

I enabled 'Simulate Physics'. When I disabled physics, that 'unbreakable chunk' became not movable mesh like Static Mesh.

I would appreciate it if you could answer for this problem.

Try turning off your Asset Defined Support and World Support settings; since you are using Support Depth you should only need those two if you are trying to build something special with your DM. You should also check to make sure you didn't turn that on any of that Chuck's Parameters.

You could also be running into bug with the DM where you can only hit it with impact damage from a particular side of the mesh, in which case you will want to reduce the complexity of the mesh or turn off impact damage and use the blueprint system to apply damage and impulse.
