Hello, I am very new here. I have been using VRAY+sketchup for a while, recently I encounter one issue. That i could only render my model with local GI or daylight, if I add some artificial lights such as rectangular lights or spot lights to enhance the shadow effect, VRAY simply just won't render the scene. My model usually is about 60mb to 100mb. I have tried with smily geometry it worked. But with complicated texture and modelling it is just not working. Once I turn off all my artificial light it will render. I also tried save it as Vrayimage, EXR, but it won't render at all. Even I have turned BFV off to use no memory. I am working on this job which is due next thursday, please help. I am using SU 8pro in Mac OS (Lion or snow leopard) for modelling, then win 7 for SU 8pro (not latest version) plus latest version VRAY to add lights and adjust settings with latest iMac.
