Texel Density Tool

Doesn't seem to work with 3dsmax 2024.2. If anyone could update this would be much appreciated.

Please when you do posts like these - describe what's the actuall issue. "Doesn't seem to work" can have millions of meanings.

I tested it on 2024.2.1
It works perfectly fine.

Please describe what is the issue and what you were expecting.

When I run the texel set function my UVs don't shrink cleanly. They all end up overlapped over each other. Is this a new bug? I'm using Max 2020.

I tried doing a Reset XForm and it didn't help. I hit it multiple times and it wasn't shrinking more so it's not that issue.

Hey guys there can be a problem if you change your second or third monitor. The problem is - script remember the position of the window.

But it not takes in a consideration that this space can no longer exist, because it remember the coordinates.

And those coordinates can be too big for your current hardware setup (if you change it for example because of the Work from home thing).

Solution is simple. Every time script closing, it saying where it saving all the stuff in listener. Like this:

Open this directory. Close max. And delete ini file. Then start max again. 

2020.3 here, works perfectly thanks

After i updated max to the 2020.3 update, it doesn't run the script anymore.

Thanks. I'll check it.

Also. Could you tell me what exactly happening when you trying to launch it?

Checked on my side on 2020.3 everything works as it should do.

Could you please describe your problem?

I was working with a spline to create a piece for a trim texture. However when I converted the spline to an editable poly the get and set were not working properly. In example I used a 4 meter piece and it would continue scaling the piece down to an incorrect size. (See attached image for comparison to a 4x4 meter plane)

I was however able to find a work-around by converting the editable poly spline into a editable mesh and unwrapping that.

Can you send me this?
Also which max u're using?

Here I did it on my side:

Also sometimes there is a problem with UV's. It is some kind of 3ds max bug, when default UV's are bad for some reason (I think it can't figure area correctly for that shell and I don't know how to fix that yet. I might need to make my own algorithm to calculate area).

Here's how you can understand that UV's have some sort of a problem - If you select and press "set" button multiple times and every time you press the button your shell become smaller and smaller - that's mean that this shell is "broken". You need to redo it, for example apply "Flatten Mapping". After you do it - it should solve the problem.

Guys pay attention. There are still some bugs.
I know about at least 3 of them:

1) Script doesn't work properly with instanced Unwrap UVW modifier. Please combine objects before adding modifier;
2) Script can give you wrong results if you didn't killed object's scale transformation (you can apply 'Reset X-Form' before using it);
3) For some objects sometimes it can't figure Texel Density, this bug seems like related to 3ds max it self. Because other instruments like "Relax" for those objects doesn't work as well. And Im not sure what causing this problems, it seems like max can't figure square adequately for some objects.

Two of this bugs I will fix in some near future, can't say exactly when, but I remember about it. Im just too lazy for the moment to do it. If you don't want to wait, I deliberately left the script open and wrote comments to each line of code, so you could fix everything you don't like by your self. About third bug as I said I have no clue how to fix it. May be I will write my own algorithm for calculating square and see whether it help or not.

Also some people was asking me to add non-square texture support. So I will add this later as well with some other small improvements.

If you found any other bugs or something doesn't work as you expected for example - please don't shy and report it.

Thanks.
