@chopsuey said: Hola! I'm making some interior (bathroom) renderings with multiple mirrors. The problem is that the reflected image in the mirrors always turns a bit purple. Here I found out, that the problem is my setting for "Energy preservation mode". I need to switch it from "RGB" to "Monochrome" >> http://help.chaosgroup.com/vray/help/150SP1/examples_material.htm BUT - I can't find where to switch this option in Vray for sketchup Help please Thomas looks like this may have to do with refraction. Do you have a plane of glass in front of your mirror? If so - either remove the refraction layer, or change to fog color to pure white. Hadn't heard of the energy preservation mode before

works great - thanks for the super description!!!!
