I tried everything what you said but i still have issue. Only one thing i found. It work normal when i changed textures to "alpha test" but that option destroyed the texture quality..
I tried "magic triangle sort" option few times but nothing happen.
Last night i tried few things:
1 - add everyone window as new subobject and add diferent textures for each
2 - add all windows as 1 subobject and diferent textures for each
3 - add all windows as 1 subobject and add one texture only
I got same issue everytime but one thing is strange. Before change anything in cutout everything was fine.
After change coordinates for textures i got that issue.
My mods right now have double windows for outside and inside but this is unuseless when we have double sided option. I will check my mods when im in home about what Scawen said and reply again.
Scawen i found one interesting bug and i have no idea what to do.
The problem is that i tried to use "double sided" option to make my xrt windows visible from both side but here comes the problem.
No matter what i use - different object, different textures or same textures always some of windows are not visible when you look them from outside.
In my case i tried to use only 1 texture for all windows.
In LFS EDITOR seems everything is okey (first pic) but in game i have that issue (second pic).
As you can see on 3th when i look from front win other windows are invisible but if i look them from right side 4th pic for example some are visible some not.
Interesting is whn i check left side there is no problem 5th pic.
It will be better if limit is higher. Some of my old mods from 0.6v have more than 74k triangles and there is no problem with the car in the game. Its possible limit to be higher but dont know exactly whats the reason for that current limit.
I found bug in lfs editor. I tried to change color of the rim bcs i saw it its not 100% whit. But when i save it after changes rim color reset to default. Another problem is i cannot change the color of the ring. https://ibb.co/HYwPxDY
I found that when i set my car view cam and close lfs my settings just gone and need to set them everyone time.. is there someone who have same problem?
Can't install test patch. I tried to my lfs version which is 0.6v3 i tried also to brand new installed 0.6v and i got same error "lfs is not found in that folder"
You got joos/oos error because you use mod who is not compatible with newest version of Live For Speed. This happens when developers changed something on .vob file.
