[Max] I need help! / Re: Scene parsing issues
« on: Yesterday at 17:42:02 »
We have this issue as well. 3DS Max 2022 service pack 3, Corona 8 Hotfix 1

Are your scene and assets stored on a local drive (e.g. C: on the computer where you are rendering) or in a network location (e.g. Z: network drive) or on a Google Drive, Dropbox, etc?

Also please feel free to contact us about this here if you haven't yet: https://support.chaos.com/hc/en-us/requests/new

some further experiment showing the "depth" it can create

So, here is the deal:

You can use the Corona Volume Material to create an object filled with heterogeneous medium.
Homogeneous = e.g. milk, where the volumetric effects are the same across the whole volume
Heterogeneous = e.g. clouds, where there is some "pattern" of things which have different density inside.
To do it, create a Corona Volume Mtl, enable the "inside volume" mode in it, and use a texture to control absorption (what is the density of the medium) and/or scattering (what color the medium has). Procedural textures will work great here as they will create 3D patterns. You can use 2D textures too, but they will not work that well as they are just... well 2D.

What I have never thought about was that you can plug the Volume Mtl as the base layer of a Corona Layered Mtl, and then you can add other layers, such as glass or metal on top. So you can create, for example, an object which is made of clear glass (or rough glass!) with a heterogeneous inside.

Here are some quick, simple examples.

The first one is "just" a Corona Volume Mtl + clear glass on top.
The second one is the same but with some roughness added to the glass, and then clearcoat on top.

I hope this can help and gives you some nice results.
The definite drawback is that this can render very slowly... to improve render times, consider the following options:
- in the Corona Volume Material - increase "step size" to get faster rendering and lower quality
- in the Corona Volume Material - enable "single bounce only" to get faster rendering and darker result with no internal light bounces

P.S. Please note that I used Corona 8 HF1 to create this scene, but I would highly suggest installing Corona 8 HF2 - which was literally released while I was typing this post. :)

You just made me realize something I haven't thought about before.
Nice pics + scenes incoming...

Great to hear that it's working fine for you now!

+1 I noticed Vray 6 was giving me better results with Normal maps than Corona.

Are you sure this is related to Mikk T support?
Could you share some examples of this? (renders, and scenes if possible)

Hi Marcin, i have an object which shows ugly artefacts in Corona no matter what normal map i use (i tried both 3ds Max and MikkT normal maps). I can provide the scene and textures privately. Curious to see how it renders in V-Ray, or other modern off-line renderer.

Hi, please send it here, we will check it: https://support.chaos.com/hc/en-us/requests/new

You can track our roadmaps under the links below. If GPU / hybrid rendering will be ever planned, you will find it there.

The solution is to sign into the Chaos License Server first, and only then start 3ds Max and set Corona as your active renderer.
Here is how to do it:
- Close 3ds Max
- Open this link in your internet browser http://localhost:30304/
- Sign in with your Chaos account
- You should see a "successful activation" message
- After completing the above steps, start 3ds Max and set Corona as your renderer

For full activation instructions, see: https://support.chaos.com/hc/en-us/articles/4642369149585

Sorry for the inconvenience. We are currently working on fixing this crash with highest priority.

As Frood mentioned, if you haven't done it yet, please contact us about your issue with the captured minidump at https://support.chaos.com/hc/en-us/requests/new

Thanks in advance.

Please try solution 4 from here: https://support.chaos.com/hc/en-us/articles/5147044693393-Corona-8-Chaos-License-Server-Basic-Troubleshooting-Steps

It looks like you are experiencing more than one issue at a time. :/

Could you please contact us here and include the information if you are using Corona 8 or Corona 8 Hotfix 1?

Thanks for checking this!

The Corona Renderer team could study what might be causing this.

Yes, definitely, but for this to happen:

Would you be able to share this scene with me? You can send a private message if you are not willing to share the scene publicly.

I think I have found the models that you used and they are loading fine here.
Are you able to consistently reproduce the issue?

Bump :)

We are definitely interested in looking into this.

This is indeed weird. Would you be able to share this scene with me? You can send a private message if you are not willing to share the scene publicly.

Have you tried using the excludes option in the Corona Decals so that ONLY the objects which the decals are projected onto are included, and the rest of the scene is excluded?
Maybe the decals are somehow projected onto a Corona Light and this is causing some issues.
