View Full Version : Vray and scale?

02 February 2011, 09:38 AM
I was wondering if it matters what scale I use in Maya when rendering with Vray.
For my architectural renderings I always model in meters (so 1 unit is one meter). But I think the standard settings in maya are centimeters.

Does it have any effect on the image in wich scale I model ?

I was wondering about this because i used an IES profile on a light and it was far to bright. I had to bring back the intensity to 0.001 to get it right (can not make it smaller).

Yes, vray depends on real units with ies lights. If it is too bright then you might have to look at using a physical camera (which you should have when doing this type of lighting in any renderer)

Tnx Hamburger
I am using the physical camera.
So should I change the size of my model, or change the Maya settings?

I think Hamburger is suggesting you can dial in the proper exposure for your image using the iso, aperture, and shutter settings on the camera instead of changing the scale/settings in maya.

Yes, that's correct. Try and leave Maya's scale so that 1cm=1cm. And instead of adjusting lights, adjust the camera's exposure settings or even the V-Ray tonemapper.

This is the usual way but of course you can do whatever works best. As long as you are happy with the final render :)

I would leave the Maya units the same but make your model actual size. SO make your model bigger.
