Accurate physics asset creation

Hello everyone,

I have some trouble with creating an accurate physics assets that goes all around a mesh without taking too much empty space around it.

Indeed I have a spaceship and when I try to apply a simple convex hull and launch game, everything goes very slow and I got freeze and less than 1 fps.

Capsule and cube are not precise and I get many empty space where there is no mesh.

Thanks a lot for help!

Hey @Krystoh!

As a suggestion, have you tried converting your static mesh into a skeletal mesh instead? From there you can create the physics asset you need, customizing it to more accurately fit your use case.

Hello @Quetzalcodename !

Thanks for your answer, however this is already a skeletal mesh, maybe I’m missig something here?

Also by the way I’ve tried to import the fbx into a mesh, then use the option in order to copy the mesh collision in order to create the physics asset, but go the same freeze and lag when I try the hull complex collision type.

Hey @Krystoh!

Apologies, I missed that since it was a solid piece. It may pay off to add an armature to your mesh. The bones can be locked in place, but you can build your more accurate physics asset around them.

Well indeed it’s a great idea, thanks I will try that and post here if it works as it should!

Hey @Krystoh!

Checking in! Did the above get the result you were looking for?

Hey!

Sorry for late response, I only got time yesterday to really try it out…
Finaly I was not able to make it work, so I added multiple cubes and lock constraints in order to make it work well. :slight_smile:
