What does the scale slider do in the Canvases tab?

I often render with Canvases and I noticed there is a new slider option in the new DS called "Scale", it's default is set to 1. Am I correct in assuming it's scaling the canvases in size? And if so, what would be the use of it. I am struggling to think of an application for this, but I am curious what it could do for users.

    This is in the nVidia docs, I am told:

    https://raytracing-docs.nvidia.com/iray/manual/index.html#reference#render-target-canvases

    PARAM_SCALE : Controls upscaling. A value of 1 indicates regular rendering, while a value of 2 will cause the rendered image to be scaled to double its original resolution in width and height. Upscaling is handled by the Deep Learning-based Denoiser, which must be made available for this option to be accepted. While the denoiser must be available, it does not need to be globally active, i.e. upscaling implies denoising for upscaled canvases without mandating denoising of other canvases.

    This sounds very interesting, I have seen upscaling used in video games as a demo in order to make games play smoother or while rendering at lower resolutions but displaying higher resolutions. Does this mean we will get an AI upscaler in Daz improving render times??

    I want to try it out, but I think I would need a card with tenser cores which are only currently available in industrial level graphic cards for data-centres I think.

    Interesting bit of info nonetheless, also the link to the Iray manual is very much appreciated. Thanks Richard !!! (Oh man, you are going to hit 100k posts today!!! I hope there is a celebration!!)

    All RTX cards have Tensor cores, as far as I know

    For those who are interested: I tried it, and the scaling slider currently doesn't do anything at the moment unfortunately. The rendered canvases are the same size regardless of the setting on the scaling slider.

    was the AI Denoiser enabled? That is a requirement for the resizer to work.

    No I used the regular Denoiser after having a second look, I went through the tabs of the render options but could not find the AI Denoiser. Is that something I can toggle in the current verion of DS or is it buried somewhere else?

    Which version of DS is this (number, channel, bit width)?

  • BlueFingersBlueFingers Posts: 895

    It's the most recent DS (4.23.0.1) , 64 bit, not sure what channel. It's the regular DS that I got through the DIM so not a Beta or anything if that is what you mean?

    Yes. Post Denoiser Available is the one that is wanted.

    Oh, than I did do it correctly. Just tried again to make sure, canvases do not scale and keep the original defined format. Should I put in a ticket? I think it's likely just not implemented yet or something, I mean,...this would be news right if DS was able to do this? Or am I missing something...

    I don't know why it isn't working fot you, but it is there and working. Of coruse if the GPU runs out of memory and drops to CPU any GPU-depenent features like this will fail.
