Changing Inst Mesh Comp Transform results in inaccurate instance collisions
Hi, I have been experiencing a very annoying bug and I finally decided to track down the root cause. Below, you will find a youtube video.
Scaling an "Instanced Static Mesh Component" results in inaccurate collisions for "Static Mesh Instances".
Steps to recreate:
Expected Result: The collision on the second static mesh instance should be rotated and scaled to accurately fit the visual result of the static mesh.
Actual Result: The collision does not get scaled, and is merely rotated, resulting in inaccurate collision and the player can clip through the left and right side of the cube mesh.
Why I believe this happens: Setting the transform of an instanced static mesh component causes all subsequent instances to potentially have inaccurate collision. Some instances will have correct collision while some will have completely incorrect collision and this depends on each instance's transform values.
I have included a youtube video for demonstration to help illustrate the bug.
