[Max] Daily Builds / Corona Curvature Map playground!
« on: 2022-01-27, 14:13:18 »
We have the long-awaited Corona Curvature Map in our newest daily build!
You can check the full changelog and grab the installer here: https://forum.corona-renderer.com/index.php?topic=33839.msg194357#msg194357



This is an early implementation and it may still change based on your feedback, so please let us know what you think about it, what is great, and what isn't.
We are also very interested in the differences you notice between the Corona AO and Curvature, and when exactly you would choose to use which.

Basic usage:
Create a new Corona Curvature Map in the material editor.
Plug it into any material property you wish, or use it as a mask to mix various properties/materials.

An example where AO and Curvature produce a similar result:
https://corona-renderer.com/comparer/ZYyww6

An example where AO and Curvature produce a visibly different result:

One of the major features of the upcoming Corona Renderer 7 is the new Corona Physical Material. With the introduction of this new material, we also had to update our Corona Converter script.
This thread is intended for collecting feedback on everything related to the new Converter script (its functionality, features, issues, what you like about it and what you don't like).

More about the Corona Physical Material:
https://blog.corona-renderer.com/behind-the-scenes-the-physical-material/
https://forum.corona-renderer.com/index.php?topic=31802

What you need:
- Corona Renderer 6 (to see what the render looked like before the conversion) - https://corona-renderer.com/download
- Newest Corona Renderer 7 daily build (to convert the scene and check the conversion results) - the link to download the newest version is at the top of the newest post at https://forum.corona-renderer.com/index.php?topic=30876.0
- If you just install Corona 7, the converter script will be available under the right-click quad menu as usual. If you are using some alternative installation method (i.e. you do not copy any files into your 3ds Max installation directory), then you can find the new converter script in \Corona Renderer\Autodesk\3ds Max 202X\scripts\CoronaRenderer.
- Before testing, make sure that you are using the converter script version 1.51 or newer! (it is printed in the title bar of the converter window)
NOTE: When using daily builds, the usual precautions apply! Backup your scenes!


What we are especially interested in:
Corona Legacy Material to Corona Physical Material conversion. This is the most important thing for us.
- How similar are the conversion results?
- How complex are the resulting shading networks in the material editor?
The easiest way to test both those things is opening a scene created in Corona 6 in Corona 7, converting it, and rerendering it.

What else is important:
- We improved the conversion of VRay2SidedMtl to CoronaPhysicalMtl. If you have a scene where you used the VRay2SidedMtl, please test this, and let us know if anything does not look or work as expected.
- Please check that all buttons in the "Tools" section of the Corona Converter work as expected. While this may sound like something our internal tests should take care of, there are always some edge cases which we might have missed, so we appreciate testing even very basic features like this.

Known issues and limitations:
- We know that the shading networks created by the Corona Converter might be quite complex in some cases (especially when many texture maps are used). If you have some ideas how to simplify such cases once you encounter them, please let us know.
- The newly created CoronaPhysicalMtl will only use those parameters, which were also available in the original material - i.e. if the original material did not feature sheen or clearcoat (which is the case for CoronaLegacyMtl), the converted CoronaPhysicalMtl will not use neither sheen nor clearcoat parameters (you can, of course, enable these parameters manually).
- It is possible that we changed some MAXScript function names which our users may want to use (i.e. broke the MAXScript API described here: https://www.racoon-artworks.de/CoronaConverter/mxsDocumentation.html ). The reason for this is that we used our coding conventions during the last rewrites of Corona Converter and therefore we changed some function names which weren't conforming to these conventions / weren't descriptive enough. If this proves to be a significant and commonly encountered problem,  we may revert some of these changes.
- We are planning to remove some legacy options / buttons from the Converter. If you rely on the removed functionality, we will consider reverting some of these changes.
- We do not support conversion to CoronaLegacyMtl anymore. The materials are always converted to CoronaPhysicalMtl.

Additional notes:
- Vray Mtl to Corona Physical Mtl conversion may currently not be working perfectly, but big improvements are coming!
- Specular to IOR conversion is a work in progress


If you have any other notes / remarks / complains - please do let us know.
Thank you in advance for your feedback!

DISCLAIMER:
I wrote this script as an exercise, as a private person, it is completely independent from the works of the Corona Team. This is a private, for fun, after-hours project. It is absolutely unofficial, provided as-is, and does not come with any kind of warranty or support.

What is it?
It is a floating window with a collection of various tools / settings which you hopefully may find useful when using Corona's IR.

How to use it?
Step 1: Back up your whole scene, or at least render settings. I mean it. I don't take any responsibility in case your scene gets broken (e.g. your current render settings, including camera settings, disappear).
Step 2: Click buttons.

How does it work?
It modifies some render settings and 3ds Max Environment settings. It does not modify any magical settings which are normally hidden from the user.

[Max] Daily Builds / Improved Sun & Sky model playground!
« on: 2020-04-29, 15:15:30 »
From the Corona Renderer 6 Daily Builds Changelog:

  • Implemented new and improved Sun & Sky model
    • Supports sun below horizon
    • Current version does not support turbidity, but it will be added in next iteration of this model
    • Can be selected by using "Improved" sky model in CoronaSky map (this is now the default)
    • Can be selected by unchecking the "Use legacy color" checkbox in CoronaSun (legacy mode is available only in old scenes)
Give it a try and share your results!

Disclaimer: it looks crazy good. Keep that in mind!

The newest daily build of Corona Renderer supports Phoenix FD foam and splashes!


Quick how to:
- Get the newest Corona Renderer daily build (16.04 or newer) - https://coronarenderer.freshdesk.com/support/solutions/articles/5000570015
- Get the newest nightly build of Phoenix FD (6.4.2020 or newer)* - https://forums.chaosgroup.com/forum/phoenix-fd/phoenix-fd-general/956950-how-to-get-nightly-builds
*Older versions of Phoenix FD are supported too, but may not work correctly with Corona's interactive rendering (glitches, freezing, crashes), and may not contain some other bugfixes.
- Load an existing Phoenix FD simulation or create a new one - https://docs.chaosgroup.com/display/PHX4MAX/Example+Scenes
- Make sure that Foam and Splashes are enabled in the Phoenix FD object and start the simulation (or resimulation) - https://docs.chaosgroup.com/display/PHX4MAX/Liquid+Foam
- Apply any material to your liquid mesh (preferably some kind of liquid ;) )
- Optionally: adjust the settings of your Foam and Splashes particle shader objects
- Optionally: enable motion blur in your Corona Camera - it's supported for both the liquid mesh and foam/splashes!
- Optionally: enable caustics to become the cool kid - https://coronarenderer.freshdesk.com/support/solutions/articles/12000056738
- Render!

I would like to start a quick discussion about how Corona Volume Grids are expected to be handled by different render elements. Please express your opinion how it should be working with each render element, and provide example workflows if possible (e.g. "I would like to render fire in front of a character and then be able to adjust the color of both the fire and the character behind it in post using masks").

---> Here is a simple scene to experiment with, saved in Max 2018 format: [link]
