Chaos Corona 10 for 3ds Max Daily Builds Discussion

You can grab the latest build from: [Daily Builds Changelog](https://forum.corona-renderer.com/ Chaos Corona 10 for 3ds Max - Daily Builds Changelog )

Note that as usual, we are waiting with next version daily builds until we release a hotfix for version 9 (containing only 3 minor fixes).

Meanwhile we have a changelog with 29 changes so far for the first daily build, so stay tuned :wink:

Woooo! Exciting.

By the way, not sure if it’s something you’d want to change for 10 DBs or even Corona 9 Hotfix 1, but when we install Corona 9 in our studio as an update it does not effectively check to see if a newer version of Max is installed. So we recently installed 2023 and had to go to ‘advanced’ in the install when we upgraded from Corona 9 latest DB to Corona 9 official. Not a big deal, but might make life a little simpler for people. FYI.

Hi danio1011,

I understand the problem here, however the installer can’t detect whether the version was newly installed or simply unselected by the user.

Sorry for not being able to provide a better solution here.

Cheers,

Rowan

“Corona now correctly resolves in which volume the camera lies. The camera can also be given a non-zero physical size, in which case the camera might lie only partially in one volume (e.g. camera half-submerged in water)”

Will this have any influence on how vol obj and VDBs behave regarding if the camera is in this object? I.e. so we can actually have the camera inside said volumes?

  • I noticed the vol material itself has the option to “mix vol objects” so they can intersect when using the vol material, can this function be added to Corona Vol objects so we can mix VDBs?
6

Yeah, this is how it works

VDBs are already always mixed mixed together :smiley:

Cheers!

Hi guys, what is this element in the new release:

  • Added tonemap control viewport shader (as no-op)

Can’t find where and what it is…

Thanks!

8

Hey,

Sorry for the confusing changelog entry, it just displays the map plugged into the shader in the viewport. Previously it displayed black in the viewport.

Cheers!

Thanks! Was easy at the end! :smiley:

hey guys - what does this mean exactly?
Corona now correctly resolves in which volume the camera lies. The camera can also be given a non-zero physical size, in which case the camera might lie only partially in one volume (e.g. camera half-submerged in water)

11

Hi,

I guess we need to work on making the changelog more human readable :smiley:

It means you can now have a camera within a volume and the volume will render correctly. The example above would mean a camera inside the pool water for example. It can also be half in/out of the pool water and it will render correctly: Camera inside volume | Corona Renderer

Cheers!

12

Camera inside volumes → thanks a lot for this. We had to wait for a while but it was worth it :smiley:

13

Hmm, this isn’t what I have experienced over the past couple of projects. I see a clear outline of the “box” container where two or more corona vol object containers (loaded cloud VDBs) intersect. Will do a ticket and include sample scene soon :wink:

14

Another one where some clarification would be nice :wink:
“User can now set how volume (volume material, sky volume effect and volume grid) interact with alpha channel. + Semi-transparent volumetric effects now also contribute to alpha channel for rays not hitting anything”

Does this mean we can get something similar to the Vray environment Fog effect / Aerial Fog effect while still being able to use an HDRI?

Right now we are loving the corona sky fog option, but it’s very frustrating and limiting not being able to use it with an HDRI. This is probably the only thing I really miss from vray.

15

Hi,

That behaviour didn’t change, right now the volume effect is only compatible with the CoronaSky.

Cheers,

Rowan

16

That behaviour didn’t change, right now the volume effect is only compatible with the CoronaSky

Yeah, but any plans to change that? It really would be good. (just picture me saying it’s something we need, in your next daily, Rowan :wink: )

17

Are there any plans to make the clouds work with the volume effect? Seems a bit weird right now when two brand new options on the CoronaSky isn’t compatible

18

Hi,

Volume effect does indeed need some work, and we have these issues logged.. but I don’t have any timescale for when we’ll get to them. The info I have is that it is not simple at all to fix..

I’m sorry not to provide better news on this.

Thanks for understanding guys

I’ve been getting significantly more crashes with IR running and the latest Corona 10 daily (11-25.) Grabbed a dump and posted it with ticket #70823. It will occur randomly but most predictably when I hit ‘Stop’ in the VFB when IR is running.

Thanks,
Daniel

EDIT: Actually it seems that the crash results from having two copies of the same PhoenixFD fire in the same scene with IR running and me hitting ‘Stop’. And the crash occurs with Corona 9 stable, too. Hopefully this post and my ticket are still relevant and solvable.

Would be great if this release could FINALLY stop the IR window from resizing when you click it.
