[Max] Feature Requests / Re: Rendering Corona Volume Grid in Render Elements

Yup. Another must have would also be the ability to add VDB objects to the 'CShading_Mask' render element.

I think it would be great to also have the following if possible:
- base colour
- raw lighting (similar to the geo version, where the VDB is shaded grey, hough I'm not sure what other tech settings would need to make this happen, as I have never seen this in another renderer before).

Thanks Fluss :D

Next up, another close up teaser image focusing on the skin texturing and shading. This is one of the main characters, Captain Corliss "The Red Snake" Vail.

Also, can we please have VDB's appear in more AOV's, like normal and depth, much like how other renderers can like Arnold.

I may be responding to this thread in bits and pieces to try and keep information as bite-sized as possible.

By having the VDB invisible in some AOV's, is the renderer wasting time sampling pixels behind the VDB, even though they are never visible in the beauty pass? That seems inefficient.

I guess what I am saying is that the VDB should be visible in all AOV's for maximum render efficiency.

[Max] Bug Reporting / VDB "Visible to Camera" attribute not working as expected...

« on: 2020-03-18, 04:24:53 »

I have come across another issue with VDB's, where the "Visible to Camera" attribute doesn't seem to be respected. In the attached image, quality issues aside, on the left the rocket smoke VDB "Visible to Camera" attribute is turned off, and on the right it is turned on.

Regardless if the attribute is turned off or on, I would expect the VDB to cast shadows on to the surfaces, but it seems that with the attribute off, the VDB seems to not even cast secondary rays as well as primary rays. More specifically, I would expect the surface area 'A' to have a similar amount of shadow from the VDB as surface area 'B'.

Hey maru, yup, both points are correct.

Also your twist on carving out a fake hold out by using a pure black colour is a good idea for the time being. Thanks!

artofcharly: thanks again for your support :D

mferster: I intend to write up a number of making of articles after/around the release of the film. Stay tuned!

The next update involves showcasing an asset from the film: Captain Corliss 'The Red Snake' Vail's trusty side arm, 'Skysong'. Thanks for viewing!

What makes it even more tricky/annoying is that because of the bug where if you have a visible VDB grid in the scene when 'Render selected' is set to 'Include/exclude list' then the list is completely ignored. I can't generate an alpha of the VDB grid with all of the scene lighting and materials affecting it in the RGB channels at the same time, and have the scene objects hold it out (objects can be in front, behind and inside the VDB grid at the same time).

I currently have to render a second pass where I apply a black material to all scene objects and make the VDB grid render with a constant white colour, then shuffle that into the alpha channel of the VDB beauty render in comp.

Am I missing something here, or is what you are describing simply turning off 'Visible to Camera' in the object properties?

[Max] Resolved Feature Requests / VDB's not holding out in some AOV's

« on: 2020-03-10, 04:33:21 »

It seems that some AOV's can not be used properly when a VDB grid object is in the scene. If there is pixel coverage of a VDB object, I would expect that coverage to hold out what ever data is behind it. As it is currently, I can not use a number of AOV's in comp because it is not being evaluated in those AOV's.

For example, I can't use an RGB mask to isolate other objects behind the VDB grid. Other AOV's I would expect the VDB grid to hold out is in source elements and texmap elements. There are more as well, though I'm not sure how they would be rendered correctly (zdepth, UVW, position, etc.).

In the attached example, there is a VDB grid of rocket smoke in the middle of the image in the beauty pass, but there is no evidence of it in the attached AOV's.

Thanks for the kind comments :D

A new image posted on the 'socials':

So much work has gone into Cyan Eyed to date, and a lot of detail can be missed. While not from any shot in the film, this teaser image is to show off the work done on the cloth materials.

Work on Cyan Eyed has continued on at a steady pace since my last post. 70% of all shot tasks (camera, animation, FX, cloth, hair, lighting, environment and comp) is done. Shots are now starting to get approved with final comps. I'm now going to be posting more images on various social media to help build more awareness up to the release of the film. I would be grateful if as many of you could like/share/follow/retweet/react to as many of these as possible.

Thanks!

[Edit] I think this image could technically be considered a 'finished' piece of artwork, but since it's related to the film which isn't done yet, I posted it here instead.

[Max] Daily Builds / Re: Adaptive enviro sampler playground!

« on: 2020-02-22, 10:14:47 »

Yeah, I'm now finding that my earlier excitement is probably overstated too much. I mean, I think it is an improvement, just not to the extent I was reacting to before.

In the images below, the first image is a previous frame I rendered on one of my Threadrippers. I then rendered the same frame on my workstation (my render boxes are tied up currently). I still see a fair amount of noise in the new adaptive sampler. Is noise being calculated differently now?

I should have put this info in the images:
01 - v5
02 and 03 - v6 daily

[Max] Daily Builds / Re: Adaptive enviro sampler playground!

« on: 2020-02-22, 06:07:46 »

Holy crap, this new adaptive sample is blowing the previous one out of the water. I have only done one test on a small image for now, but the results are night and day. In the example 10 minute render below, v5 got to 8.46% noise level. the v6 daily got down to 0.43% noise level! FYI, the black areas are a hold out I setup to speed up rendering.

Also not to mention the speed ups in the geometry stage. This is insane, my renders are going to be so much damn faster. I am very impressed.

FYI, Darktable is the open source equivalent to Lightroom, and it can read exr's. No need to screw around Lightroom's limitations with file formats and Adobe's predatory tactics in general.
