Is it possible to render a region that is not a square. For instance I am trying to render a series of images that are very high resolution with a square aspect ratio. Lets say 3000 by 3000 for each.. However I only need about half of those pixels. Specifically if you draw a triangle with 2 points…

I think he just confused the terms “square” and “rectangle”… as far as I understand, he’s asking for non-rectangular render regions.

only equiangular quadrilateral is possible - no random shapes. I guess it would be useful to have the ability to ‘mask’ areas to render for future release? could be really useful.

Thank you Deflix. That is exactly what I am referring to. Some kind of masking ability (other than a rectangular box) detailing what is being render to limit calculations would a great addition to Vray.

So you would use black&white image to tell V-Ray where to render, is that what you mean? Best regards, Vlado

That would be a very useful feature. For now just create an object and link it to the front of your camera, creating a custom matte box. Apply a black material and make it a vray matte object that ignores lights and GI. Done.

Thanks raven, That’s worth a shot… But will be a bit cumbersome with stereoscopic renders But otherwise great idea. Thanks.

Create the first one, place it where you need it. Then align its pivot point to that cameras pivot. Clone then align clone to the second camera using pivot points. The real trick I guess with stereo (I’ve only toyed with stereo, never done any production), is that it will need to be pretty close …

Sort of like the Priority Map in Brazil R/S: [image] It’s a black and white image, where white is the most prio and black is the least.

But isn’t it a bit cumbersome to switch programs just to choose a render region? How about a normal selection lasso in the VFB? (ideally with “vertices” that can be moved after drawing it, like when you’re scrubbing through the animation and see, that you need to make the mask bigger here and there,…

Imagine a scenario where a small part of your animation needs re-rendering on every frame; being able to keyframe those points throughout the animation… Now that would be something! I guess very hard to implement though.

Which cloud rendering system to use?
