Collision Mesh Not Importing

Development Pipeline & Plugins

Hello there. I’ve made a mesh (2 actually), for a physics based game, so I need 100% accurate collisions. So I’ve duplicated the mesh (Shape2), and exported it as UCX_Shape2, both as FBX. On engine import I’ve unchecked the “Auto Generate Collision” and the “One Convex Hull Per UCX”. My problem is, that when I import the mesh, the collision won’t get imported. Anybody knows why is this happening?

The files:

SM_Shape2.fbx
UCX_SM_Shape2.fbx

And here’s what the mesh looks like:

Thank you in advance!

Hey Lostra,

This sounds correct. I see it looks like you’re using 3Ds Max. You could try adding a “_01” to your UCX and see if that works.

I’ve got a simple tutorial I’ve made on the forums a while back that walks through custom collision and how to set it up from beginning to end in 3Ds Max that may help: [TUTORIALS] Photons Be Free: Mini-tutorials and other curiosities - Community & Industry Discussion - Epic Developer Community Forums

Let me know if that works for you.

Hey Tim,

Got it fixed later on. It turned out I’m the stupid one, and the meshes needed to be in one single FBX. This is what you get when you neglect modelling for a year. Thank you for the answer tough!

Great! I’m glad you’ve got it working. :slight_smile:
