[Max] Bug Reporting / Re: CoronaMultiMap seed changes with animated camera

« Last post by dzintas on Yesterday at 13:59:43 »

Hi,

I have checked the scene and unfortunately this is expected given how the VRay proxy is animated.
The number of faces (and effectively their indices) changes, and so does the randomization.

I think the workaround is to have different IDs for the roofs and randomize by Material ID instead of Mesh Element.

Hope this helps.

I'll try it out if encounter this bug again. At the moment just smoothed over the flicker in post and work on it is finished for now. Unless we get some revisions.
About the process, for example my roof material. I need to create multiple material id's for same roof material just to have some randomization to happen?
Kind of complicates the process a bit.
Other thing, would this happen if I use point cache or corona proxy instead of vray proxy?

Work in Progress/Tests / Re: Juraj's Renderings thread

In the workflow I tested, I was using upscaling inside ComfyUI (so, Stable Diffusion run locally). I did indeed crop the whole person (and some surrounding area as it was a crude rectangle mask, which I would mask out when overlaying into the image, so I drew the more detailed mask at the end as it happens :) ), as I wanted to improve the skin and clothing overall as well as the all-important face. Hope this helps!

I will leave Juraj to comment on his workflow :) I have tested something similar this last week though, using ComfyUI, and I can say that trying to do "face improvement" at 512x512 does not work, it just uglifies things :) For me I had to take a crop of my test image which ended up being 374 x 669, upscale it through a 4x upscaler to 1496x2672, then pass that through the Realistic model with 0.49 denoising, and then it improved clothes and faces. Trying to do that on the original crop with no upscaling just made things worse - so in the way I had things set up, a) you are not limited to 512 at all and b) 512 makes things worse.

This may be dependent on GPU memory though.

For interest, this was on a 4080 laptop GPU with 12GB memory, with similar performance seen on a 3070 Ti desktop. It was about 60 seconds to process the crop (that is to upscale it with a face sensitive upscaler, and then feed it through the model, combined in that time)

Also Tom (sorry to hijack the thread a bit here feel free to move into a new thread), i'm assuming here that your crop was of the whole person, so in effect the face was much much smaller than 374 x 669 crop.  The upscale then allowed the 'face' to fill the 512 marquee better in the resulting 1496x2672 image giving more starting fidelity for SD to work with?

@maru Do you have 3990x and 3970x machine on latest build Win 11 and latest bios/chipset drivers etc..to test these files?

I can't share the files due to NDA. So I will have to create a test file to upload..

Hey Tom, are you referring to an  external upscaler like Topaz here or an AI upscaler inside Stable Diffusion, just wrapping my head around all this stuff

You would need to plug supplied opacity texture in the material's opacity slot. It also could be a good idea to plug that material into Corona rayswitch material and populate all its slots except GI, so that your floating decals won't cast the shadows.
