Non-uniform scale collision issues

I mirrored a static mesh piece along one the Y-axis and I get a warning when I build saying…

[StaticMesh] has simple collision but is being scaled non-uniformly - collision creation will fail
Simple collision cannot be used with non-uniform scale. Please either fix the scale or the collision type.

In the static mesh editor, I’ve set all 3 options for the Collision Complexity, and I get the same result. How do I properly set the Collision Type?

Hi Charles,

Does this occur with multiple static meshes when scaling them non-uniformly or a particular one?

Also, could you attach a screen of what it is you are attempting to accomplish so we have a clearer picture?

Thanks!

Is there a way I can attach a video? It would help explain it a lot better. I tried attaching a .mp4 but it said the file type was invalid. I can cook it out as something else.

Perfect. I uploaded the file. It’s in CharlesHuenergardt/RocketMirrorYBug.mov Please let me know if you need anything else.

Charles,

Thanks for posting the video; I can now see what it is you are trying to do. Unfortunately however, I am unable to reproduce the issue you are encountering by using static meshes that are supplied with the editor. Does this issue occur only when using the piece in the video? Does setting the Collision Complexity to Default do anything?

Alternatively, if you want to upload your project files or export that piece and post it in the same place on the FTP, I can grab it and take a closer look at what is going on and try to help solve your issue.

Thanks!

Thanks for taking a look! I posted the entire project. The map is Example_Map. You’ll be able to see the hallway and the room. It’s a fairly small map that I’ve been using to test stuff out.

The issue seems to occur on the HallStraight piece as well as the HallCorner piece. I didn’t try all of the pieces, but my guess is that it’s all of them. They have custom collision build in Maya. The FBXs are in the Content->EnvironmentKit folder

Hi Charles,

I’ve taken a look at your project files and can now see the issue you are having. Setting that static mesh piece to use Simple Collision as Complex did provide collision for the piece, however it did still generate the warning you were seeing.

I then exported that piece and attempted to replicate the issue on our latest internal build and set the piece to Complex collision which provided collision for the piece and did not generate the warning as seen in the current Rocket Build.

I would say that you can verify this in the next Rocket release and if the issue still persists, for you to reach out to us again. For now, setting the collision as Complex appears to work if you can disregard the warning until the next release.

Thanks!
