I’m trying to mirror the physics assets capsules from the right side of the body to the left side however it does not work at all. Sometimes they will be way off after mirroring. It’s very tedious trying to line them up and make it close to symmetrical.
Is there a way to fix this?
Hi there @celestia
Are you using ‘mirror bodies’ in the the physics asset tool? I’d start by checking and make sure your bones having proper naming conventions. (_L and _R or Left and Right etc)
It just says “Mirror” not “mirror bodies” in the physics asset tool when I right click on a physics asset capsule that I want to mirror.
And everything does have the proper naming convention. My character is using the UE4 mannequin skeleton.
Oh, I see. This isn’t really using the mirror tool. But, you could try going into the physics asset editor and right click a bone that is being mirrored in the hierarchy panel(One of the L or R specific bones), and choose ‘Copy Body from’ and select the opposite bone to the one you selected. (thigh_L to thigh_R etc). That’ll copy all of the settings from the left thigh and apply to the right. Sometimes I find that easier and more precise to do than using mirror.
Oh! My apologies. When I saw the UE4 Mannequin I made an assumption you were on UE4. I think the option got removed in UE5. I looked to see if I could find a work around for it. Try this:
Select the capsule on the working/right side (e.g., thigh_r).
In the viewport, hit Ctrl+C (this copies the shape’s relative transform and size).
Go to the corresponding mirrored bone (thigh_l).
Hit Ctrl+V – it will paste the shape, but it’ll be positioned wrong.
Manually flip the mirrored axis in the transform:
Usually, flip the X location
Then Invert rotation on Yaw or Roll, depending on how your skeleton is oriented
Let me know if this works.
Oh I should have specified I was on UE5.5 sorry. I think I figured it out. The rotation settings were kind of hidden in the Primitives section in the details panel of the capsule. Flipping the X location and then flipping the rotations there fixed it. Thank you!
Ah, right on! Well, I’m glad you got it fixed!
