Ray Tracing Shadows Missing with Clothing Data in 5.6

Hi!

I just upgraded a project from 5.5 to 5.6 and noticed an issue only present when Ray Traced Shadows are on.

I was using a low res mesh to feed a hi res mesh for my Clothing Data and was disabling the associated section to hide it. Had no issues until my upgrade to 5.6.

It’s quite easy to reproduce: The character ‘Echo’ in the Game Animation Sample with 5.6 shows the exact same issue.

Is there an updated workflow for this matter without having to move to new Chaos Cloth, or it’s just a bug?

Thank you in advance!
