Invisible skins

[fringe egret]

my shaders are correct but nothing

I think the problem is here with the things undefined

Because my whole scene is on blender 4.5 and I can only export in blender 5.0+

so when I try to import models from blender 5.0 texture doesn't work anymore

I think it's because separate bundle doesn't exist in blender 4.5 so is there another solution ?
