Re: Need help I think I have a bug

Are you using the new sun? I am just starting to play with it (is there any documentation anywhere?) and if I use the default settings it is very very bright- so much so that all my materials are coming out black and white.
Hide the sun and the results are predictable. I am using IM + LC too.
This is VfR4 beta 2.

(We need a beta 2 bug thread. And while we’re at it, why not delete or archive all the original VfR beta threads?)

Did you make sure the Color chooser is correctly set at the top of the render viewport (ie: Red, Green, Blue?)

Or we make one big SR beta bug thread, because some beta 1 bugs are not fixed.

Sky and Sun: if the physical cam is used, than the brightness should be right by adjust iso/shutter/f-stop. But the DOF dosn’t work with phys cam. So, I stick at standard camera and use a colormapping multiplier of 0.04 … 0.02.
