One of my biggest issues with making ship addons is that for some reason no matter what i do, space engine doesn't recognize every material that the model is supposed to have. For instance, with my U.S.S Vengeance model that i ported, its missing its windows, this is because when i try to include it, space engine only puts the models base texture on it instead, and even when i add the material in the sml file, nothing changes. To me the game only seems the notice the materials that it happens to notice, being only up to 3 through testing.

This to me doesn't make sense since i know space engine allows you to use multiple materials on a single ship model, but no matter if i add the materials in the sml file, name the material file pictures names the same as in blender, nothing works, after you refresh the game after loading the game the first time, the materials it recognizes is what you get, and you can;t seem to change it.

I've been stumped for months on this and have found no solution no matter where i looked on the space engine website or on other sites. I can't figure out what i'm doing wrong. Is it how my model is layed out in blender? Are my export settings incorrect? Is there a specific way that i'm supposed to layout the materials in the sml files? Am i not supposed to use blender at all? I'm not sure at the moment.

This issue is the reason why the star trek ships i've added have no windows, decals, and other features that are supposed to go with them, but couldn't add because it seemed like if i wanted to do that, i'd have to somehow combine all the textures into one (which wouldn't be possible without their being either an obvious drop in texture quality or many noticeable inconsistencies).

If anyone knows some information or could perhaps give a detailed guide on how i can fix this, I would greatly appreciated it!
