Hey, as there are really few frame models in Radiant, I'd like to create some by reusing the frames and changing only the picture in the middle.
If I just copy / paste a frame model and change the picture .tiff, it doesn't work and creates errors in ModTools.
I guess I need to use APE but I don't know what to do at all

Is there any way to do a variant or something like that ?

You need to use APE...........

Of course you need to use APE, how else will the game convert the image properly.

Here is a guide on custom textures: https://confluence.ugx-mods.com/display/UGXMODS/BO3+%7C+Adding+custom+materials+and+textures

Did a test and this is what found out. It's  possible to duplicate model. I copied the bin file and renamed it. Opened up ape and searched for renamed model then added new texture. Did it to a brick wall model a broken part model. Thing is texture doesn't match up. Not shure if this can be fixed must do more testing.
