When i want to export a xml file, it can't find the texture that i linked in blender, even though, it is in the textures folder. Can someone please help?
Where is your blend file saved? I usually save the blend file in the same directory that I want the IGS (source folder) There are also some settings for texture path in IGS options, check the manual.
As a side note, afaik BPE/ConvertToTG now only accepts uncompressed 32bit ARGB textures (no more DXT1, 3 and 5).
