I’ve been playing with the latest V6 Render Engine (currently in beta / early-access, to be released soon). I used the same John Randal McDonald Vanderbeke model from the SketchUp Warehouse in this post (8 months ago): John Randal McDonald Vanderbeke Home from SketchUp Warehouse. The progress is impressive!
Here are some of the neat improvements:
darker / richer tones
better color balance
more balanced contrast
less plastic like aesthetic at high prompt strength values
What parameter are you using? im keeping my settings default but i getting a really bad output. and all outputs are different from eachother even with the same settings.
