rendering in 16 bit or even float does not increase rendertimes at all, only amount of disk space the images take. rendering happens in floating point, and when the image is written out it is converted to 8bit, 16bit or 32bit according to the image format.

Is rendering it in 16bits a big hit on the rendering time? I am going to test it now.

Hi, We are a little perplexed why we are getting this dithering in the dark areas using final gathering on some machines and not other on a small rendering farm. We are using XSI 7.01, Mental Ray and Royal Render. I have attached the comparison Any help will be appreciated. Thanks, Leoung -- Brandt Animation www.brandtanim.co.uk 020 7734 0196
