SketchUp to ArchiCAD to render - glazing is coloured?

[Anonymous]

To do quick mock-up renderings I've decided to try importing my SketchUp models to ArchiCAD and using the built-in Cinerender to generate my renderings.

The model imported from SketchUp perfectly with all textures, etc., including a fritted pattern on the glass. But when I render, the glazing looks orange in colour.

I've tried changing various render settings, the sky, etc. etc.

But in the rendering, the sky seems to cause the glazing to have an orange tinge to it, no matter how I change the settings. When I change the sky to another preset sky without an orange tone, it switches right back to the standard "Clear" sky, and causes the glazing to have that orange-colour in its reflection. Any thoughts?

I realize these could be really stupid questions; I'm just new to this and haven't been able to tweak the rendering settings to fix this problem.

Thanks in advance.
