BimX Global Illumination-Black materials

Has anyone run across this while running Global Illumination? (see attached pdf)

The file is quite large, 1.7 gb teamworked. We have generated smaller areas of the model with great results.

Just wondering is there is a size limit or something else that would change how materials would be rendered. They look fine prior to GI.

Thoughts?

We are having the same issue but get varying results across 5 different kinds of graphics cards seem to be the constant.
I'm having success with - ATI FirePro W7000 (4GB) and GT 650M 1GB

Jet black textures in random places with Nvidia 980GTX (4GB), Nvidia 750 GTX Ti (2GB) & ATI FirePro V9700 (2GB).

The problem areas change between runs and are not consistent locations.

I'm aware that the patch note fro 17.8000 Build 156568 was supposed to address this issue caused by certain graphics cards, notably with the Firepro W7000 or the GT 650M there never was an issue at any point, whilst all the other cards remain unchanged by the patch regardless.

Has anyone got any idea on how to remedy this?

We are using GeForce GTX 760 (2GB) and have tried multiple configurations with no luck at this point.

We are playing with the resolution settings and turning off intense objects within the model at this point.

I will update you more as we get information.

If we export/save the BIMx from ArchiCAD with the ATI FirePro W7000 (4GB) or GT 650M (1GB) and then run Global illumination on the Nvidia 980GTX 4GB or Nvidia 750 GTX Ti 2GB (these are faster cards=half the compute time on average) we get sporadic results - some GI runs now show no black materials, some do, but this is better than the all failed runs we were consistently getting previously.

I am not sure if this is valid information or not as I had to remove a link that was just an add.

What Archicad version and operating system are you using?
