[Max] Bug Reporting / Re: Scene Color Selector Bug

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 »

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.

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 »

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!

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?

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!

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!

Still on Corona 8 as I need a stable release for production - 2023.2.2 did not fix the render setup crash here.

Is this in the viewport or render? I had the same problem (in 3ds max viewport) and what helped was to plug the same map using a regular bitmap and then change back to corona bitmap. No idea if that will help you, but thought I'd mention it.

Very nice, materials look really good. Did you have any specific workflow here?

[Scatter] Feature Requests / Re: Chaos Scatter feedback

Thanks for the scene, my last question for the time being. What is the specification of your computer?



Hi, these are my specs. Let me know if you need anything else.

Intel Xeon W-1290P CPU @ 3.70GHz
NVIDIA GeForce RTX 2080 Ti
128 GB RAM

[Scatter] Feature Requests / Re: Chaos Scatter feedback
« on: 2022-08-05, 12:42:03 »
I'm using Chaos Scatter to distribute trees on a 1800x1800m terrain surface. I have two scatter types, one for deciduous trees and one for pine trees. The two types are scattered on the same terrain, but driven by a black/white map that defines where the trees should grow according to how high up they are. I also have multiple splines set up to exclude scattering in some places.

My problem is that the scene has become incredibly slow, selecting the terrain or scatter objects and making adjustments takes so long that it's impossible to work with. Finding it hard to work if I have to disable the scatters every time I need to make a change, and simply selecting them and disabling takes a long time. Also, I'm planning on scattering other vegetation like shrubs and grass on the same terrain, but it looks like this isn't going to be possible using this technique.

I think the mask is slowing things down a bit, but the spline excludes slows even more.

Disabling the spline excludes in the list doesn't help the performance, but deleting them eliminates the issue.

Is this to be expected using spline include/exclude, or is this a bug?

I'd like to investigate this issue, it sounds like something isn't quite right there. Would you be able to share your scene with us?

If so I'll PM you a link to upload a file



Sure, I made a copy of my scene and I can upload it. Thanks :)

@Bjoershol, you could try to disable automatic update in the scatter's display settings and see if that helps.

Thank you romullus, that makes it easier to work with. Hitting the update button takes about 8-10 seconds, but at least the wait is confined to pushing that one button. :)
