Hi there, I did the Update to V5.0.2 and downloaded Chitubox V1.6.1 to give it a try. Chitubox V1.6.1 creates .photons - Files, no *.pvs. Photon-S V5.0.2 does not accept .photons - Files anymore. Only *.pvs. So we need an Update here. I Can't use Chitubox V1.6.1. I'll wait for a Chitubox-Version that creates *.pvs.
