Hi Peter ,
what is your hardware setup? and are you using the latest approved graphics driver for your visualize version?
Hi Scott, here are my System specs.
I´ve found another bug: Lighten with HDRLightstudio5 and Visualize 2018 in Hybrid-Mode, freezes the preview rendering inside Visualize
after a while.You can move the lights inside Lightstudio and the HDR-Thumb in the environment panel is updating, but preview doesn't.
Stopping Lightstudio, changing from preview to layout and back, or assigning another environment doesn´t work.
You have to close the project. GPU-only Mode works fine.
