You dont need to learn blender, you can just click file>import and then click the UV tab at the top, would be a fast way to just rule it out.

I have exported glb's that use color instead of texture that work just fine but probably not in the same use case as you. The video in my first post on this thread you see me do it with glass and metal objects.

If you want just upload your 2 test glb's I can take a look.

Ah, apologies, perhaps I misrepresented the problem.

Just to confirm; The mesh imports fine, I just can't apply a baked texture map on a BasicMaterial to the model.

Thanks for the offer. I might take you up on it and upload some files shortly.

Did you try import into blender and check the uv's. I see in your second image no id's for texture (since there are none).

Also, what happens when you assign a default gltf material and export (with no textures)?

tbh I'm trying to avoid blender (I don't use it, and don't want to incorporate another software into my process).

But yes, that's what I was trying to show - it exported without UV's. The one without UV's was indeed exported with your script with a default gltf material (with no textures).

I do see that exporting from blender to gltf has the tickbox option to export UV mapping even when exporting with no materials/texturees. I guess we're just missing this from Max...

Hi James, and thanks again.

So I think I have confirmed that it is losing it's UV mapping thanks to gltf.report

Attached are the reports for the export with the texture map applied...


And this is the export without the texture...


I'll keep digging, but I think this is a 3dsmax related issue.

Hi James,

Been using this a lot lately. Can't thank you enough for the script and all your recent help.

A query which I hope you might be able to shed some light on...

I'm building an interactive page for model viewing. My process is to load the model using js model loader and then apply a new material (created in the js file, with a jpg texture map applied to it) to the loaded meshes. I've got it all working fine.

However...

If I export a mesh/model with a gltf material applied WITH a texture in the base color map and load it into my scene, all works well.

If I export a model WITHOUT a texture applied to its material the js material doesn't seem to work properly.

I think the uv mapping is being lost in the export. Is this possible?

From my tests it seems that this is not a result of your script, but a universal particularity of gltf/glb exports.

Is there a way to export a glb/gltf without any material/textures applied but still retain the uv mapping?

Apologies for the highly specific and technical question. But, as you've proven, I'm certain you're the right person to ask :)

The above is definitely a bug, thanks for bringing it up.

I reproduced it and it is reported now.
The solution is to select an object which does not have CoronaPatternMod applied, and then select object with pattern. The select and move will work fine afterwards.

(Report ID=CMAX-1430)

Excellent! Thank you :)

Not sure if this has been discussed, but it'd be really good if the viewport behavior of objects with CoronaPattern applied is different.

If I click on an object with CoronaPattern applied and press Z (or zoom) to zoom on this object I get a zoom to BOTH the object and the pattern object.

Sometimes the pattern object is 1000's of units away from the object it is applied to and I cannot properly zoom. It's very frustrating behavior.

Food for thought. Thanks.

It has been in my mind since the very first implementation of pattern.
Unfortunately it is a 3ds Max limitation (how zoom to selected works) we can do nothing about.

Thanks for the reply.

Unfortunate!

Ok, another one for you; It seems when I have an object with CoronaPattern applied I can't properly do a 'crtl' drag and copy. It makes a dupe, but it doesn't place it where I want and it inactivates the 'Select and Move' tool.

See attached. Any thoughts if this can be fixed to expected behavior?

Thanks.

[Max] I need help! / Re: Very strange result, possible solutions?

« on: 2024-12-06, 13:00:21 »

From a very quick look, it seems like it could be from modelling errors (NaN's?) and/or smoothing group issues?

I'd rebuild those surfaces with the problems and see the result again.

General CG Discussion / Re: Feeling Cheated by Corona Renderer: The Impact of Auto-Renew During Black Friday

« on: 2024-12-03, 15:01:42 »

I'm not defending this, by any means, but I am genuinely curious;

My understanding is that your auto-renew already probably gives you a significant discount? My current subscription is the same price, but if I ever stop or cancel it, I believe it will increase. This is a sort of carrot that was offered to existing yearly subscribers when Chaos increased the Corona prices a year or so ago.

So, I'm wondering if you were to try to take advantage of the black Friday discount, perhaps your subscription price would have increased (by cancelling it) enough anyway that any discount would have been negligable?

Just theorizing, nothing here is researched or accusational :)

So, turns out the answer to my original query was known already.

Thanks to RenderRam for pointing it out in a recent video.

Damn, I either completely forgot this, or have never noticed.

I can only assume it has, indeed, unknowingly caused me issues through the years.

Either way; this should be high on the priority list to fix.

I believe it is the camera tone mapping overrides which need a restart to get updated for IR, just like camera object visibility.
You can try doing batch rendering of few cameras which have different tone mapping. They should all come out with expected tone mapping overrides.

Has that always been the case?

I don't recall such behavior...

Hi,

Currently on daily build 2024-11-04 I'm getting odd behavior with my lighting in IR - essentially the lighting is all wrong between camera switches, a restart is necessary each time. Never seen this before.

I have an env override on and some varied camera tonemapping overrides, but nothing else is special.

Please see video and attachments. Thanks.

General CG Discussion / Re: 3dsmax - add a note to an object?

« on: 2024-11-29, 13:22:37 »

I found this script that adds simple note objects, but unfortunately they have to be linked to the base object.

https://www.scriptspot.com/3ds-max/scripts/note-helper

The simplest would maybe be to just put the note in the name :)

Thanks, will check it out.

I also found this which seems to do a pretty good job from a quick test: https://forums.autodesk.com/t5/3ds-max-programming/textplus-how-to-label-an-object-using-its-object-name/td-p/7014035
