Interactive rendering at a lower resolution & 2x upscaled.

[OccultMonk]

I would like to render interactively at for example at 1/2 the resolution but 2x upscaled. That would mean effectively 1/4 of the number of pixels that need to be rendered by corona. Since the size of the IR VFB floating window remains the same in that case. I have a 4K display so renders tend to become small.

At this moment I can zoom in to effectively render at a reduced resolution but then I can only see part of the image since the floating IR window size remains the same.

Not sure if this is what you'll looking for... But under the "Common" tab under 3ds Max render settings there is a dropdown menu called "Area to Render". There you can use options like blow up and such... It works with the IPR too.

Again though, not sure thats what you are looking for :)

[OccultMonk]

Thanks, I will try that. But I would also like to be able to render with 1/2 the resolution and 2x upscaled (effectively the same size viewport but 1/4 the pixels) in the floating IR VFB viewport.

You can just zoom in, in the VFB. It won't do any upscale pixel smoothing, but you can render at a small resolution and zoom in.

He writes that :- ) But then he doesn't see the full result.

It's a valid concern but not good solution. Imho we should get the nVidia instant denoiser on GPU. Interactive sorely needs it.

So basically there is no way to render IR at 1/2 - 1/4 of the resolution upscaled to full size? With some proper advanced filtering, this would indeed work even better. I am already happy if I can just render at lower res but fully scaled like Adobe After Effects. This works great for IR, because you do not need quality as much as speed, and for 4K displays, things get tiny fast. (I hate upscaling windows, I am happy with 100% at 32") But for IR VFB it is a bit small.

Windows magnifier? ;]

[OccultMonk]

That would be a horrible solution :-). Any form of native Windows scaling solution does not work for this. Very cumbersome.

Please just add a selection box with render at 50%, 25% like Adobe AE.

[OccultMonk]

Also, that suggestion about Nvidia filters would be great. Some sort of AI denoising function afterward :-) But just lower res rendering + simple upsampling is good enough for now.

100% at 32"

Wow, you have good eye-sight :- ). I run 125 at 32"/4k but only because I like real-estate, 150" would feel nicer :- (.

Check the nVidia denoiser, it's seriously instant, your interactive viewport quickly renders 5-10 passed and then it gives you denoised result but keeps improving that same denoised result as more passes comes in.
It's absolutely genial. It makes interactive rendering to be actually interactive.

Vray already has it. Now we need it too.

Yes (Render at 50% 25% resolution + good upscale algorithm + NVidia denoiser. = far better/faster Interactive rendering.

Please also look at Octane 4, has an AI denoiser that works amazingly. I know Octane render is a GPU renderer, but the denoising pass is in post.
