The debug render collision for spline mesh components using a mesh with complex collision is incorrect and is not updated to reflect changes in the mesh's deformation. The collision response itself, as well as the debug rendering by "pxvis collision" still seem to be correct.

In 4.22 this worked correctly.

Steps to Reproduce

Place a spline mesh component in the level, using a static mesh with collision set to use Complex collision as simple.

Show collision, either via viewport options, or with "ShowFlag.Collision 1"

The rendered collision does not take into account the spline mesh deformation and is incorrect.

Note that "pxvis collision" still shows the correct collision, and collision response is still correct.

This issue did not occur in 4.22.
