Thank you for your previous answer - it is not the best idea to post something on a board and then go out of office for a week

Anyway - my textures issues are exactly the same as BfPuVAK's and I am glad you will fix it soon. I made new file with 2 walls and a slab, and also got this errors: . Model looks like this ( showing the same error as BfPuVAK ): .
I also got sometimes a strange distorted and scaled textures ( when making my own archicad material ), I am not sure if it is the same reason: Btw kxl problem from few post above: I think problem might be archicad related. He probably extracted archicad *.lcf library and either moved one of extracted folders afterwards ( that might have messed up links to textures ), or haven't added textures folder to library manager. At least I had similar errors, after doing like that.
Last thing: when using some materials from liveDB - Archicad crashes ( from Material folder, OTOY materials are OK ).
I've got: "octane error has occured. pls check octane log for details" error, then "null octane node in getOctaneNodeValue for pin node transform" ( few times ), then archicad crashes ( can't do anything ).
I am working currently on dell presision 4600 with quadro 2000M, fresh win7 x64, latest notebook cuda and dell graphic drivers. ( Not a speed demon, but it's must be enough until I'll upgrade my office desktop ).
I will send you an email with *.rpt file as it is not allowed to post *.rpt file as an attachment.
thanks,
