I am re-creating the rolling ball template from UE4 in UE5, I almost have it finished, but I don’t know how to fix the collision.
the movement is based on physics, so the ball goes bouncing all over the place since it isn’t a perfect circle. and the engine won’t simulate physics, if I use complex collision. So how do I get a perfect circle Collison so I can move without bouncing all over the place?
You either need to set the collision as ‘use complex as simple’, or make the collision in Blender.
I said in my post that I can’t use complex as simple because the engine will then no longer simulate physics for it. And I have looked around, I have not seen any tutorials/courses for creating a collision in blender to send to unreal. I have no idea how to create a collision in blender for unreal to see.
Sorry, read it too quickly.
Two possible ports of call
Blender 2.8 Custom Collision for UE4 - Blender for Game Development - YouTube
Have you looked at the rolling ball template, what did they do there?
hadn’t bothered downloading UE4 as they have removed the template for UE5. Thank you for the youtube link. I will look into that later.
I just made a sphere using the UE5 mesh tool. Changed the collision to simple, added a simplified sphere collision. It fits exactly
oh I will have to try that. My ball was a mesh I imported from blender
Even so ( I think ).
Well the mesh I imported from blender to unreal gave that awkward collision too it. But I will try making it in unreal, along with that youtube video, because I would like to know how to make collision’s in blender
HI @shotty46290 , in Maya works like this for custom collisions:
UCX_“YourMeshName”_1 (Convex)
The easy way to try this would be something like this:
Create a ball - Name the ball - copy the ball - attach the copy as child to the ball
And then it should look like this in the end:
I did not use Blender but i think this should almost work the same way. There is also:
USP_“YourMeshName”_1 (Sphere)
for Spheres what would maybe would work better for you but it´s almost the same if you just copy the ball.
Edit:
Installed Blender to test this also.
So it works. You just need to parrent the UCX to the mesh you want. Looks like this in the end.
Hope this helps as a starting point.
