[Max] Daily Builds / Normal Map + Triplanar Bug?

« on: 2021-07-13, 11:54:25 »

Hi all,

I am seeing some weird results while combining a normal map made with Adobe Substance Alchemist and the Triplanar utility.
As you can see from the image, on the left I use no triplanar, only the normal map and the result is clean and correct. On the right, once I apply a Triplanar at 0.30m I get some pixelated blocks.

I am providing the scene and assets here.

Thanks,

[Max] Resolved Bugs / Nvidia Denoiser BUG

« on: 2021-07-08, 00:24:37 »

Hi!

Unfortunately I found out right now a problem with Nvidia Denoiser in RC5.
Once the image is rendered and saved in CXR format, once opened with the Corona Image Editor the Nvidia denoiser gives me very bad and strange results!
I attached a screenshot to see.

It happens with all the CXR files I have, older ones and new ones.
The latest Nvidia driver is installed and I use a 3080 RTX.

I didn't mentioned this problem in 3ds Max, when I render in the application the denoiser seems to work well, probably there is a problem withe Corona Image Editor.

Let me know if you confirm the issue.

Thanks,

[Max] Resolved Bugs / Corona 7 Displacement - Not solved completely yet?

« on: 2021-02-22, 22:11:46 »

Hi,

well, I think the Displacement issues are not 100% resolved.
This is what I've noticed till now:

1. On heavy scenes, it happened twice, the render started relatively fast (no parsing issues) but all the objects that have a displacement map were disappeared from the render.
I attached an image where this happened for the second time. No road, some trees are missing, no walls, ecc.

2. Sometimes parsing times are ok, but not always. This behavior is not constant.

Thanks and have a nice evening!

[Max] Resolved Bugs / New Physical Material Shader and Shadows bug

« on: 2021-02-10, 20:20:06 »

Hi,

I discover something weird a while ago.
I have a scene all made with the new Physical Material shader and when for an object which I need to use as a backplate in my scene I turn off "Produce and Receive shadows" from it's properties menu some weird shadows effect occur! Look at my example I post here. The shadows are produced (which they shouldn't) and part of them are missing.

Make a plane and apply the new Physical shader.
Make a box on it, you can also leave it without material.
Open it's properties and turn off Produce and Receive Shadows.
Put a Sun or HDR and render...

Any thoughts?

Thanks,

[Max] Resolved Bugs / Forest Pro + Corona Displacement = BUG parsing time?

« on: 2021-02-09, 13:00:05 »

Hi all,

I am getting crazy the last 2 days with Forest Pro and the latest 08/01/2021 daily build.
Basically I found out the problem now and I don't know if you are aware of this. Now I understood why my parsing times are huge and slow!!!

- This is what happens, you create a plane, you distribute on it hundreds of objects, more you have, worst the situation.
- Apply a material on the DISTRIBUTED OBJECTS (no displacement for now), render and the process starts almost immediately.
- Now put a displacement map on the DISTRIBUTED OBJECTS and the parsing time gets hugely high!!!

Is this related to the 2.5D mode which is the default one in the new daily build?

Thanks and let me know.

Dionysios !

[Max] General Discussion / Lights - How many we can use today?

« on: 2021-01-19, 18:34:56 »

Hi all,

I know in the past we had a limit with the number of lights we could use in a scene. Was group of 256.
Is this changed today or the limit is the same? I have a project with thousands of them and everything got so slooooooow....

Just to know before I start doing some editing and figure out other options.

Thanks in advance,

[Max] Resolved Bugs / Corona + Substance Crashes

« on: 2021-01-06, 00:21:09 »

Happy New Year to everyone and I hope you all are fine and safe.

Some releases ago, Substance materials were producing crashes when Corona was in Interactive rendering mode.
Is this still the case? I started to using it in 3ds Max 2021 and I get crashes all the time. Corona is updated to the last build by the way.

Thanks in advance and take care these days!

[Max] Resolved Bugs / 32bit EXR clamped in CoronaColorCorrect

« on: 2020-03-07, 10:37:24 »

Hi all,

I am working on a very complicated project and this morning I noticed something strange when I use a Quixel 32bit EXR Displacement map (loaded via CoronaBitmap) + CoronaColorCorrect.

1. When the CoronaBitmap is loaded by itself in the Displacement slot, everything works fine.
2. When I apply a CoronaColorCorrect on the above Displacement slot, the result is wrong it seems that a lot of the EXR information are clamped.

I attached a fast preview image, on the left the correct result with the Displacement 32bit map alone, on the right the fault result by using CoronaColorCorrect on it.

Thanks,

[Max] Resolved Feature Requests / Corona Layered Material + Multiple Displacement

« on: 2020-02-25, 11:09:56 »

Hi guys and excuse me for bringing up this issue here.

Do you plan to fix the limitation of using Corona Layered Mtl and multiple displacement maps in this cycle?
I am using multiple mix maps now (only evident solution) but things are a bit complicated as I have at least 6 different materials with different displacements and I need to apply all of them on a single terrain object by using multiple masks.

Thanks in advance,

[Max] I need help! / Produce a detailed Height Map

« on: 2020-02-19, 10:57:42 »

Hi all,

I was wondering if there is a method other than Render to Texture (the classic 3ds Max one) to produce detail height maps from a geometry by using Corona.
I have a terrain model which I would like to import as height map in World Creator to add details and then bring it map in Corona for the final render.

Thanks,

[Max] Resolved Bugs / Corona Internal Error

Hi,

we continuously getting this error during the rendering process.
The error occurs always but the rendering goes on without issues.

3ds Max 2019,
Corona 6 latest daily build.

Do you have an idea what it could be?

Thanks,

[Max] Resolved Bugs / Error Loading Settings in CIE

« on: 2019-07-16, 12:13:51 »

Hi all,

lately I am getting an error each time I try to load some previous saved settings in CIE.
This happens only if I save the settings after the usage of Nvidia and/or Intel denoise and then I try to load these settings in a second moment.

If I save the settings without having done any denoise, loading gives me no issues.

Any clues?

Thanks,

[Max] Resolved Bugs / CoronaColorCorrect rotated 90° in viewport

« on: 2019-06-04, 12:17:34 »

Hi all,

I just noticed something weird.

- Put an env map HDRI in the scene via CoronaBitmap
- In Viewport Global Settings turn on: Use Environment Background
- Apply in Active view and you'll see naturally the HDRI you use as environment in your viewport
- Now go in the Material Editor and apply on the previous CoronaBitmap a CoronaColorCorrect map
- The HDRI map in the viewport is rotated 90° !

Can you guys check as well?

Thanks,

[Max] I need help! / Displacement Artifacts

« on: 2019-03-11, 10:58:50 »

Hi all,

I am trying to understand why I get each time the vertical artifacts you can see below in my example image.
It happens with any format, 32bit as well. The bitmap is a 8K resolution by the way. Even if I try to use a checker 3ds Max map, on the Z axis I get the same result.
The only workaround I found is to use a Blur offset 0.015 on the displacement map.

The Displ. Screen Size is set to 0.4 which is actually too high quality but doesn't help unfortunately.

I know that the maps should have some blur inside but I thought on pure black and white patterns the result should be much cleaner and high quality.

Any thoughts? Am I doing wrong something?

Thanks in advance,

[Max] Resolved Bugs / Round Edge Values

« on: 2018-11-21, 11:02:46 »

Hi all,

I noticed that every time we open a scene which probably is made with a previous daily build version of Corona the Round Edge values are messed up.
For example, if I put a round edge of 2mm on a material and I open it with a different daily build version, I found the value 10x times bigger. Something like 2 meters...

Thanks,
