Okay, it's working as long as I keep the resolution within 512 - 2048!

The AI enhancing icon is greyed out in the VFB, even after adding the render element. Anything else we need to do in order to use it?

Yes, please, if possible.

You can simply open the original (or modified) scene with Corona 10 HF3.

Can confirm that the issue doesn't appear with Corona 10 HF3!

I have the same issue with Corona 11, 3Ds Max 2024.2

Loading hangs up when "loading corona assets" at 100% for a few minutes.

Hi,

We already have a "long scene loading and viewport lag afterwards" fix internally, and it was related to Scatter.
To check if this is your case, you can:
• Try installing Corona 10 HF3 and opening the scene with it.
• Try saving the scene without scatter objects, then opening it.

If in any of the cases the scene loads faster, then we will be sure that it is already fixed.
This and other NaN related issues will probably make to a hotfix.

Thank you, I tried deleting all scatters and saving - still hangs for about 7 minutes after reaching 100% before the viewport appears, then another 30 seconds until it finishes loading.

Should I still try it in Corona 10 HF3?

Oh! Yeah that solves my problem and works a lot better. Didn't know you had to manually switch to use it, thank you!

Thanks for the quick reply! I guess that's what it's called, wasn't sure because it just says "scene color selector".

Will attach a recording here.

[Max] Bug Reporting / Scene Color Selector Bug

« on: 2023-08-25, 10:02:52 »

Hi,

I've had some problems setting colours in my materials lately. Not sure when the problem started occurring.

Basically, when I try to adjust the colour in a material, it kind of locks in place or will adjust the hue as I'm changing the saturation.
As an example if I try to increase the saturation the hue will change from red to more orange as I go higher.

I've tried switching between Scene and Display Referred thinking it might have something to do with it, but doesn't make a difference.

« on: 2023-06-29, 12:36:46 »

Thanks so much Maru! I have a lot of RAM, so I might try this and see if it works. If it's too much I might try dj_buckley's suggestion and convert it to geometry! Thanks both :)

I actually didn't realise Scatter can be used in grid/running grid distribution, and it follows the curvature of the surface which is perfect. Learned something else today!

I used ScatterSurfaceColor and mixed it in with the material on top, that way I can drive it using a bitmap which I can take straight from the landscape plan. Should be a fast way of doing it if my computer holds up :D

[Max] I need help! / CoronaPattern path / color variation

« on: 2023-06-28, 16:05:09 »

Hi,

I am trying to find a way to create a brick pavement using CoronaPattern, but I'm finding myself stuck. Have managed to make the pattern with some basic color and texture variation (using CoronaMix and Randomizer), but I'm struggling to find a way to create a distinct color pattern on top of that. The pavement is suppoosed to have a defined path using only colors, while the tiles themselves stay the same shape, etc. It's kind of hard to explain, but have attached an image of what I'm thinking of.

Does anyone have a method for making something like this? I know I could use decals or a distance map, but I don't think I'll be able to line up the colors with the tiles that way.

I'm not sure if this has been mentioned already - but I'm pretty sure the cloud shadows change or move somehow when rendering compared to how it looks in interactive rendering.

Trying to render some buildings where the sun is just hitting them and keeping the surroundings in shadow - but can't get it to match with what I'm seeing when testing in interactive.

Thank you for the recommendation! I should look into it.

I found that the problem is actually one of the objects I've put into the scene, which for some reason crashing the program.

I opened it separately and converted from Physical materials, and it looks like it worked!

Hi,

I'm trying to render a scene that I have worked on previously, that was pretty slow but rendered with no problems.

All of a sudden today I am getting this error - I have a lot of scatter objects and such, but disabling them isn't helping.
128GB RAM should be more than enough, anyone have any idea what's going on?

In task manager, Memory at 99% or 100%.

Also feature request - i would love to have an option for partial cloud coverage. No need for something fancy like painting maps for explicit control, a simple spinner "horizon bias" would be already great - quite often IRL you can see beautiful clouds over horizon, while sky overhead is completely clear, it would be nice to be able to replicate this in Corona.

Clouds look great, can't wait to try this out!

[Max] Resolved Bugs / Re: max 2023.2 crashing when closing render setup dialog

« on: 2022-09-30, 09:27:09 »

last few weeks were rough, yesterday this issue also prevented me from sending jobs to the render farm. I was up till 2:00 AM uninstalling and reinstalling max didn't help. I have to finish 3 projects by mid next week. why is this happening? so no fix to 8.2? why?

I don't know if it will help you, but someone said that assigning a different renderer in Render Setup and then switching back to Corona will avoid the crash. Need to do it every time you restart Max, or assign a different default renderer. Hope that can help!
