@gtavjamal Just updated Zmodeler to the 3.2.1 version and all features are working. I can say more that the game stopped crashing for me with no reason .

@drlq99 Ok, material names are saved correctly in .z3d file.

But I think i found the reason why the [PAINT:6] suffix is not saved in .yft file.

I use 3.1.2 (build 1123) version of Zmodeler. The highest suffix which can be exported is [PAINT:4]. When you put the [PAINT:5 or 6] the suffix is not saved.
So shitty the re is no any alternative program to edit material names

@gtavjamal If you are not getting any errors while importing the model, then you have all textures the vehicle needs.
But from my experience, if you will missing some of them Zmodeler will not delete them from the materials list anyway, so the car will load the missing textures from in game archives .

The most common missing texture is ofcourse env.dds .

@drlq99 So when I load the z3d file and edit material names in it then export it as .yft file the changes should be saved also right?

@drlq99 Checked all possibilities Nothing work.
I discovered one thing. When you change material name, or simply delete any character, the changes are not saved during exporting. When you import the model all material names are untouched like they are before editing.

I'm wondering how's that possible?

I've added manualy the suffix [PAINT:6] at the end of the material name and this not solved the problem. Should I also include the "" symbols?

Hello!

So the problem is that after you export the car mod via Zmodeler you are unable to change the interior colors in game via trainer. It stays at it's base color. I though that it is related to model editing.
So I imported the model (where the interior color change was working in game) and then saved it again without any editing, loaded the game and the result is the same, interior color does not change at all.

I did not changed any shaders or textures at all in model materials so I'm getting lost tat that point.

What parameters should I change in model settings before exporting it by Zmod to get interior color change later in game?

Best regards.

Probably not all axes are centered in wheel hierarchy. Check every entry if this is a whole car mod or the wheel model itself.
