@flying_bulletzzz One more thing; there's a weird checker pattern on the piece of clothing when I select a specific accessory. With lighter and darker tiles.

@death7991 Thanks anyways for the help.

@death7991 Nvm it worked. But how can I ,,embed'' the ped_default shader ? Because when I look at the default GTA clothes, they don't have a second ID under editable mesh in the dropdown menu.

@death7991 Ok, so I painted the vertices in 3DS Max. The model is orange in the OpenIV viewport, which I suppose is the correct color, but the gloss is still there.

@death7991 How does it work in zmodeler ? I tried it once but the piece of clothing gets the same shader assigned like 100 times and the skeleton doesn't work anymore.

So I have this problem for months now; everytime I convert a piece of clothing with 3DS Max and use it in-game, it becomes glossy after a while. I already tried to move the specular intensity slider all the way to 0, assigning and removing the specular map and so on. I paint the vertices the right color, and still, nothing works. I also don't know how to keep the ped_default shader, since it disappears after I export and import the model into 3DS.

@Warlock2011 Are you also using Open All Interiors with the ,,Enable MP map'' setting enabled ?

@Lil_Shrimp Import into 3DSMax.

@Lil_Shrimp Get Crowbar and Blender source tools, covert the .mdl files to .smd or/and .qc with Crowbar, import them into blender, export them as .obj and import them in 3DSMax or ZModeler3.
