I noticed an issue rendering skatter grass after I updated from Sketchup Pro 2017 to 2018.
I can render any kind of proxy except skatter grass.
When Vray does “Compiling geometry” it doesn’t matter how much grass I render but the image doesn’t process.
The frame buffer stands black.
I just noticed something weird happens in the history (see image attached): last image has “-447h”, so I’m rendering back in time!!
