[Max] Daily Builds / New bloom and glare playground!
« on: 2020-06-04, 17:20:00 »
In the newest daily build of Corona Renderer 6, we have brand new lens effects!
You can find them in the VFB Post tab, and then tweak your bloom and glare using the built-in aperture editor.

Share your results, ask questions!

[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!

[Max] Daily Builds / Phoenix FD Foam and Splashes playground!
« on: 2020-04-17, 11:26:30 »
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!

[Max] Feature Requests / Rendering Corona Volume Grid in Render Elements
« on: 2020-03-27, 11:52:23 »
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]


Original thread:
https://forum.corona-renderer.com/index.php?topic=28143.0

List of all Corona render elements:

CESSENTIAL_Direct
CESSENTIAL_Emission
CESSENTIAL_Indirect
CESSENTIAL_Reflect
CESSENTIAL_Refract
CESSENTIAL_Translucency

CGeometry_NormalsShading
CGeometry_UvwCoords

[Max] Tutorials & Guides / Why were Dubcat's threads removed!?!!!11

Dubcat's threads were removed per Dubcat's request as they were outdated and doing more harm than good. Stay tuned for the updated versions. :)

[Max] Daily Builds / Adaptive enviro sampler playground!
« on: 2020-02-21, 10:15:06 »


The newest daily build of Corona Renderer (20.02.2020) features a new adaptive environment sampler, which is enabled by default. It greatly improves image quality in areas where direct environment lighting is visible and should remove the need for portals in most scenes:
- The difference is mostly visible when using an HDRI for environment lighting.
- There is also a difference when using Corona Sun+Sky, mostly in cases where the sun is not the main source of scene illumination (if strong sunlight shines into the room through a window, the improvement probably won't be that visible).
- When using a solid color for the environment lighting, there will be no difference.
Generally, this does not improve rendering scenes with Sun+Sky or solid color environment, because those are already greatly optimized.


To compare the new and old enviro sampler:

Method 1 (using two Corona versions):
1. Render your original scene using Corona Renderer 5 - https://corona-renderer.com/download - this will give you an image with the old enviro sampler
2. Install the newest daily build - https://coronarenderer.freshdesk.com/support/solutions/articles/5000570015
3. Render the same scene using this newest daily build - this will give you an image with the new enviro sampler
Do not change any render settings between the two renderings!

Update: the below Method 2 is not valid any more, because in the latest daily builds of Corona Renderer 6, portals are completely ignored by the Corona core.
Method 2 (using a single Corona version):
1. Install the newest daily build - https://coronarenderer.freshdesk.com/support/solutions/articles/5000570015
2. Open your original scene
3. Render - this will give you an image with the new enviro sampler
4. Go to the "Development / Experimental Stuff" rollout - https://coronarenderer.freshdesk.com/support/solutions/articles/12000021288
5. Under "Lights" switch "Enviro sampler" from "Adaptive sampler" to "NormalDep Compensated"
6. Render your image - this will give you an image with the old enviro sampler
Do not change any other render settings between the two renderings!

Note 1: the tests can be repeated with and without portals used in your scene.
Note 2: it makes most sense to compare renderings using the time limit - e.g. rendering the same scene with 10 minutes time limit with the old and new sampler.
Note 3: to quickly switch between two versions of Corona, or even launch two 3ds Max instances running different Corona versions at the same time, you can use this simple trick: https://coronarenderer.freshdesk.com/support/solutions/articles/12000066819

[Max] Daily Builds / Masks in reflection/refraction playgound!
« on: 2020-02-03, 18:04:20 »
As you may have noticed, there is a new feature in Corona Renderer 6 daily builds, which lets you store masks of objects seen through glass and reflected in mirrors:
Quote
Masking render elements can be propagated through refraction/reflection. To propagate them you have to set it in the material (Corona Mtl -> advanced ->propagate masks)
https://coronarenderer.freshdesk.com/support/solutions/articles/12000066916-how-to-use-masks-with-reflection-refraction

Please share your experiments here and point out any possible issues/requests/doubts as we would love to see how exactly you are using this feature, and make sure it works as expected in Corona.
I am also attaching a very simple scene here, which can be used to try it.

[Max] Daily Builds / Caustics playground!
« on: 2019-04-23, 20:27:19 »
Today marks the day when Corona + Caustics became reality!
We hope that you are as excited as we are, and that you will share your experiments in this thread!

The daily build is available to all license holders. Info and download:
https://coronarenderer.freshdesk.com/support/solutions/articles/5000570015

The new caustics can be enabled with a checkbox in the Performance tab.

Any tests are welcome, and we are super interested in your feedback.
