Hi all.

Appologies if this has been answered before. (Please see attached image). I seem to get cyan casts most of the time using direct lighting. I know this is only a preview kernel but are there any tricks to minimise? I have played with AO and saturation but cannot seem to erradicate unless in post pro (photoshop etc).

Kind regards

I think it has something to do with the scale of your scene. Try playing around with the scale a bit and see if it helps.

Thanks Daniel, ill try that. I use default export settings from sketchup so I assume it would be ok?

Cheers

The direct lighting kernel assumes that the indirect light has approximately the same color as the environment, in your case the blue sky, hence the blue colors in shadows.
