[Max] Feature Requests / Faster volume effect/ aerial perspective

« on: 2023-11-25, 19:16:12 »

Hi all,

As far as I can see in my tests, volume effect makes renderings take twice the time, making it unusable in my workflow.

With Unreal engine and other render engines having real time atmospheric effects, I wonder if it would be possible to have a much cheaper option to adding depth.

Thank you.

[Max] I need help! / Reflections override: Strange behavior - Bitmap on screen mode

« on: 2023-10-04, 18:44:35 »

Hi,

Please, take a look at the videos below.

On the first video:
When I isolate the object the reflection looks as expected: screen mode.
When I exit isolation mode it becomes stretched. Why?

The object is a box with a reflective material.

On the second video:
An empty scene with a box with reflection and a bitmap on reflections override.
It doesn't look stretched, but there's a second image being reflected.
Is this normal?


I'm working with Max 2023 and Corona 9, windows 11.

Thank you.

Hi Corona team.

Is there a way to exclude xref scenes from the caustics calculations?

Thanks.

[Max] Feature Requests / "Open" button in VFB to be able to open an existing CXR

« on: 2023-05-12, 15:42:15 »

What I want to do is, after the vfb was cleared for whatever reason, I want to be able to use the region tool knowing what I'm "regionining", and on an already rendered image and not on a black or extremely noisy background.
It's not fun to wait for parsing, or a frozen UI.


Please, refer to this topic for more info:

[Max] I need help! / Fireflies more frequently with V9

« on: 2023-04-10, 23:54:06 »

Is it a known issue that V9 may render fireflies more often?
That's what's happening to me in at least 2 or 3 scenes now.

[Max] I need help! / Corona Select in Background slot displaying incorrectly on viewport

« on: 2023-04-05, 16:22:52 »

It seems that corona select isn't displayed correctly in the viewport.
I have several background images on screen mode, but with corona select they are displayed as spherical, seemingly.

Attached a screenshot.

Hardware / SSD vs HDD in terms of rendering performance

« on: 2023-02-09, 17:14:26 »

Hi all,

I have an HDD with my library for textures and models.
I've had it for almost 10 years now.

I was wondering if anyone knows if it's worth it to switch it by an SSD in terms of performance for everyday workflow and rendering.
Anyone with that experience?

[Max] I need help! / [solved] Corona pattern. Automatic height

« on: 2023-01-25, 16:51:25 »

Hi,

Shouldn't "automatic height" keep the height proportionally correct regardless of mapping or tiling?
In this video I used a small cylinder as the node. But when on the pattern, it gets distorted in height.

[Max] Resolved Bugs / Slicer doesn't seem to work like in version 8

Hi there,
Please, see video below. Am I missing something? Or the slicer is broken?

[Max] I need help! / Corona Sky still too blown out and faded

« on: 2022-12-13, 18:00:38 »

I know that the sky had a lot of development in the last couple of years, but I still feel it has the same problem as usual: It completely goes to white on a huge area around the sun location. It just doesn't look realistic anymore now that cell phone cameras got so much better.
Below I have a very simple scene with a sun/sky at defaults, and some geometry blocking the sun. As you can see the grey of the walls (default corona physical material grey) looks ok, but then the sky looks completely white, and the areas that do have some color look very desaturated.

Is there any way to reduce the glare of the sun to just the circle of it and leave the rest as blue sky like in the photo on the top right?

Thanks.

[Max] Feature Requests / Camera motion blur - edit shutter to higher than 1

« on: 2022-12-12, 23:59:29 »

As I understand, the 'edit' pop up window in the 'shutter curve' within the motion blur rollout allows you to set the motion blur from 0 to 1, which would be the equivalent of fully closed and fully open.
What if...we can set that value to 5 for example, to allow for a very exaggerated motion blur, while keeping DOF at a normal level?

[Max] Feature Requests / Thumbnails for CXR files

« on: 2022-12-11, 19:37:05 »

When going through my CXR files it's often very hard to know which image it is.
It would be very helpful to have thumbnails on windows explorer.

Thanks.

[Max] Resolved Bugs / IR doesn't refresh when numerical transform on editable mesh subobject

« on: 2022-11-07, 17:35:16 »

Please, see the video below.
It seems that when I do a numerical transformation on at a subobject level, IR doesn't update. This doesn't happen with edit poly.

This was a new scene.

[Max] Feature Requests / Tone mapping - Shadows and blacks

« on: 2022-10-12, 19:58:34 »

Hi,

I find it very hard to bring shadows up without flattening the image. The options, new and old, on the tone mapping area all seem to give a Reinhard effect.
It would be great to have the attached controls to level the contrast better than the tools already in place.
The attached was taken from the Photoshop camera raw.
