Blocky Shadows in Path Tracer ?

[hoejeon]

Hi,
Currently testing Metahumans and Path Tracer in 5.2, i’ve got these blocky shadows visible on the clothing and on the mannequin. No problem in lit mode.
After tinkering a bit, it seems to be the dynamic shadows but i’m stuck as to the exact cause and solution

First pic is PT, second is Lit.

Thanks !

Whilst its not the best fix I found turning off dynamic shadow on the torso removed the issue until the bug gets fixed

The same issue for me, have you found a better solution?

This looks like a shadow terminator problem. The only way I know to fix that with the path tracer is to use a higher polygon mesh.

Here’s a detailed explanation of what is happening.
