[Max] Resolved Bugs / LUT error when opening Corona 8 scenes

« on: 2022-04-17, 16:09:25 »

With Corona 8, I get an error message every time I open my scenes. It says that Corona couldn't load my custom LUT. No matter how many times I reload the LUT and save the changes, the error will show up when I open the scene again.
This never happened in previous version.

[Max] I need help! / [Solved] Increasing "Render multiplier scale" in planes makes huge in viewport

« on: 2022-04-12, 17:35:04 »

It only happens while rendering, doesn't matter if it is with IR or production. Once you stop rendering, the plane goes back to normal size.

This is kind of awkward since the "Render multipliers" properties are meant to affect how the plane looks on the rendering not on the viewport. As I've mentioned in other posts (https://forum.corona-renderer.com/index.php?topic=36097.msg197203#msg197203), having a huge plane on the viewport creates some annoying issues when you need to zoom extend/out and navigate, specially when the main object of the scene is very small compared to the big plane.

[Max] I need help! / How to create an "infinite" desert like this?

« on: 2022-04-11, 18:05:12 »

How would you approach the creation of an "infinite" surface like a desert with no visible mountains on the background?

This a situation where having a tool like the Vray infinite plane that could be mapped with some displacement map would be of great help. Since we don't have anything like this, I'd love to hear how you would achieve this effect.

By the way, I've tried using a really big plane in the past for this kind of scenarios. However, this creates some annoying issues when you need to zoom extend/out, specially when the main object of the scene is very small compared to the big desert plane.

[Max] Feature Requests / Improve the way we save images in the VFB

« on: 2022-02-18, 15:53:34 »

Any plan to improve the way we save images in the VFB?
We're really missing some basic features that would make our life easier such as the ability to store rendered images by project with all their post rendering corrections. Stored images should also remain after a new Max session, which is not happening right now.

My client sent me some pantone color references to be used in our project. What's the best way to get accurate representations of this colors in render?

Hardware / Is there something better than the 3990x coming out next year?

« on: 2021-12-21, 02:20:14 »

With new CPUs to be released next year, I wonder if getting a 3990x right now is still the best choice.
Is there something better on the horizon?

[Max] Bug Reporting / HDRIs connected via Corona Select map are not previewed correctly in viewport

« on: 2021-12-19, 18:29:47 »

I've been trying to use a Corona Select map to quickly switch between HDRIs, as mentioned in the helpdesk:
https://coronarenderer.freshdesk.com/support/solutions/articles/12000057928-corona-select-material-and-map

However, once connected to a Corona Select map, the HDRIs are no longer previewed correctly in the viewport.

[Max] I need help! / How to create one-way mirror

« on: 2021-12-07, 22:03:42 »

Hi everybody!

How can I make a 1/4" one-way mirror? As you know this type of mirror has a highly reflective coating on applied on one side. How can I do this in Corona? SubObject material?

By the way, the goal here is to create an infinity mirror by placing some lights between a mirror and a one-way mirror.

[Max] Resolved Feature Requests / New triplanar option: Align maps parallel to longest axis

« on: 2021-09-07, 20:35:08 »

Dear Corona team,

I wish there was an option in triplanar map to automatically align maps parallel to the longest axis of objects.
This little option would save us so much time and effort.

[Max] I need help! / Clear coat absorption as "stain" parameter for wood materials

« on: 2021-09-04, 20:58:26 »

From what I got on the last Corona 7 webinar at 10:58, clear coat absorption could also be used as a "stain" parameter to completely alter the color of wood materials without having to use new textures or color correction node.

So I could start with a basic natural wood texture and then play with the absorption parameter to find the right stain color. Is that one of the intended used for this parameter?

General CG Discussion / Using Adobe Camera Raw to post-process EXR renders

« on: 2021-04-10, 04:42:17 »

I've been trying to use Photoshop to post-process my EXR renders just like I'd do with DNG files. You know better than me the difficulties of this, since Adobe Camera Raw does not support 32 EXR files. My current workaround is to check the "Use adobe Camera Raw to convert documents from 32 bit to 16/8 bit" option in Photoshop preferences. This way, every time I load a 32 bit EXR render in Photoshop and change from 32 bit to 8 bit, Photoshop will launch ACR in order to tonemap the image. 

However, after messing around with this method for a while, I've started to question myself wheatear this is really working or not since it doesn't really feel like editing a real RAW image. I mean, am I really being able to access the whole dynamic range of the EXR using this workaround? If you have already tried this method, I'd love to hear your thoughts about it.
