Google Sketchup 8.0 PRO and then just exporting through the SkIndigo.

v3.0.17, the sun is above the horizon.

I've checked the setting in indigo which were just set at default (white point at D65) and the environmental settings on sketchup which are default. :/

I'm a beginner to indigo renderer, everything has been fine until recently when i tried to render a simple model and whilst renderer it appears to have a pink overlay.
any suggestions of fixing this?
