VRay's ppt rocks!

[studioDIM]

I'm probably raving, here, but i kept thinking about what Vlado said about "Distributed" ppt.

Maybe i missed he implied that the sampling level for each image has to be exactly identical for them to merge properly...

Or not?

help...

Ideally the images should have similar noise levels, yes. Otherwise, you have to weigh them appropriately based on the noise levels (e.g. more noisy images should have lower weight). But it's easier if all images are similar (e.g. with the same number of light cache subdivs).

Thanks Vlado, it's a nice clarification...

There's a usability problem there though: i'd have to know what number of subdivs is good enough before rendering the final frame, rather than doing like i am doing now, cranking subdivs to 65k and stopping at leisure when the results have converged enough.

EDIT: The problem seemd to be in the fact that using Max's own VFB (and interrupting the render) would save images as clamped, while using VRay's HDRIs are saved properly.
So there is no usability problem, as long as the speed of the network PCs is the same, and the renders are started at (roughly) the same time.

I'd try the weighing, knowing which is the procedure...

Well, instead of setting high subdivs and stopping the render, you'd have relatively low subdivs, but render lots of frames... in this case, you can also at any moment grab the rendered frames and do the final image.

Here is a link to the image blending proggy: http://www.spot3d.com/vray/help/VRay...s/blendimg.rar

If you start it at the command line without arguments, it will print a short usage notice. Currently supported formats for both reading and writing are .png, .hdr, .bmp, .jpg, .tga
