I have imported objects from archieve.3d.net, to the project.
When I do the normal rendering the images are correct. But when I exported to BIMx it is coming pink color, I ticked the check box from Publisher set to render with Generate Global illumination for realistic shading (This will increase rendering time). Still I is coming pink.
I have shared the screenshot, Object looking in AC, Rendered image, BIMx object after GI.
Archieve.3d.net is not a BIM platform.
You are able to find some gsm but not lcf files.
LCF are contener files which could include texture but not into a gsm file.
So you must rebuild you surface into archicad with internal engine and maxon engine.
IG is not able to delete texture into your BimX.
