hi, i have been working with Vray for a while now, but i keep running into the same trouble with the settings every now and then. I tried doing some research on it in the books, but i guess i am the only one that does not fully understand how things really work because most books/tutorials skip the setting up part.
The problem is this... i import a lot form autocad into 3dmax, in autocad we work in millimeters.
if i put my unit setup to generic and the system unit scale to millimeters i continuesly have trouble with shadows and have to blow up my lights big time. So the question is, how does the unit scale influence the shadows etc.
I tried rescaling the worldunits on my selection by a factor of 1000 but that made some parts shrink and others stay big. Scaling them down the normal way doesnt seem to alter their behavior on the shadowpart.
furthermore i also have the impression that VRAY is made for a standard scalesetup since i get a lot of trouble with spots and grain in my renders.
i hope anybody can shed some light on these points or point me towards a comprehensible tutorial that adresses these issues.
many thanks
tunes
