[Max] I need help! / Re: Node to rotate a texture?

« on: 2024-04-13, 05:58:14 »

Ideally, you would use the OSL UVW Transform map and it should be enough, but it simply multiples the input values, does not transform.

While this:

OSL might do what you're after, maybe?

works exactly as you would expect. So give it a go.

P.S. it actually works for CoronaBitmap too (instead of OSL file name map), it is just 3ds Max that does not show the node connection lines, but it is there.

Hi,

I am not sure I exactly got what you wanted to have (a screenshot or image would help here) but from what you have described, I am sure that it is well possible to do with Corona decal.

If you want, share an image of what you want to get and the sample file, and I will help you out.

[Max] I need help! / Re: Caustics and Texture baking in Corona 11

« on: 2024-04-04, 04:33:43 »

Generally, I would not have high expectations with texture baking, but it seems that the available render elements for baking in Corona give mostly the beauty (whole lighting information, including caustics), for the selected objects with the specified UV map, which I think can be used, at least to some degree, for baking.

I would go with the trial and error approach.
You can have a look at the screenshot and scene attached.

[Max] I need help! / Re: Render output looks completely different from the file saved yesterday.

« on: 2024-04-04, 04:10:15 »

Random though: maybe you have changed the system units (by opening another scene or simply changing them) and when opening this scene back again, you did not adopt this scene's units? This can cause misinterpretation of lighting objects size (including lightmtl objects) which can affect their lighting too.

But from the first glance, it seems a tone mapping/color management issue.
Please check if you have Gamma workflow or OCIO in 3ds Max color management.
If you have OCIO, then the result in Corona VFB is linear (not like what you would see with Gamma workflow, even with tone mapping). If you have gamma workflow, then it should work fine.

In any case, try changing the Color management settings just to see if you are able to get any of the results (original or the modified one) with any of the color management settings.
If you are able to consistently get them, then we will be sure that this was from sudden change of color management settings.

I want to have composition and resolution lock in vray camera

Hi,

Do you mean per-camera resolution (composition) lock (and other options I suppose) for CoronaCamera?

[Max] I need help! / Re: Ctrl+Z (Undo) Crashing Max

« on: 2024-03-28, 10:41:17 »

Not quite, as it is a separate plugin which also received updates. I am not sure how the installation was done on your side though.

Just search in Add or Remove programs (installed apps on windows 11) for 3ds Max Scene Security tools.
If it appears, you have them, if it doesn't, you don't.

[Max] I need help! / Re: Ctrl+Z (Undo) Crashing Max

« on: 2024-03-28, 09:03:04 »

Has anyone experienced Ctrl+Z or Undo in general consistenly crashing their scenes?  I'm in Max 2024 and Corona 11 - pretty sure it's a Max issue though.

But I'll start a new scene and everything works fine for a while.  Then (randomly) Ctrl+Z will crash Max, and from this point, any instance of Ctrl+Z in that scene results in a crash.  The rest of the scene works fine but once I've had that initial crash - Ctrl+Z becomes a no go zone.  It's driving me insane.

Hi,

This seems to be the known behavior of the malware found in the scene.
Press H and check if there are any objects (they are usually empty) with strange names (the ones I am aware of were Chinese).
If you found any, deleting them will not work - you will need you download and install [urlhttps://apps.autodesk.com/3DSMAX/en/Detail/Index?id=7342616782204846316&appLang=en&os=Win64]Scene Security tools[/url], then reopen the scene.
It will automatically detect the malware and delete it. Afterwards, you can locate and delete the objects with strange names.

[Max] General Discussion / Re: Chaos scatter randomization

« on: 2024-03-27, 14:07:45 »

Hi,

This is expected and that is how randomization algorithm works, there is not much you can do about it.

But you can do a simple trick - for the base color slot of all the vehicles, plug an extra CoronaMultiMap with, say, 3-4 different colors, randomized by instance. This way, even if the same model appears twice in a place, there is a much higher chance that the other instance will have a different color, thus making the randomization seem more random.

[Max] Feature Requests / Re: tile map on decals?

« on: 2024-03-21, 18:23:50 »

Probably a use case will be to change the UVW Xform/tiling for many decals with one modifier? This can be done by instancing the decals (knowing/planning before), or wiring parameters, which is indeed cumbersome.

I think UVW Xform modifier support for decals is a good idea.

It would be nice to have a simple notation added that could be used to increment the offset for each subsequent row, so like in this example you would have just have something like 0.14* 1 1
instead of 0.14 1 1| 0.28 1 1| 0.42 1 1| .....


Is that something that can be added? I can put in a feature request in a forum post if needed.

I believe it is simpler to do the math and input/type the values only, than to type the math operations in the input field. And what if the offset is not constantly incremented over the rows?
The input of "a b c | a b c " is not ideal, but it works in a straightforward way.

This is very interesting and atmospheric work, to the point. And not an ordinary use case of Corona :)
Great job!

Hi,

Please find the attached scene.
It is absolutely possible to do this with Corona Tile map but you need to math a bit and type patterns to get it. I have done it for you for these specific tiles.
For detailed explanation on how the custom pattern works check this:

https://docs.chaos.com/display/CRMAX/Corona+Tile+Map

under "Click here to see custom pattern usage illustration".

Hope this helps.
