I want to export a scene from Blender in fbx format for use with Unreal game engine. For materials the objects have baked texture maps, which would be presented in Unreal as such. Are texture images packed into a fbx file, or does the file only contain instructions for loading an image file? What is the best procedure for fbx exports of objects with texture images? Should the images be packed into the .blend, and does it matter if the Blender scene is using Cycles or Blender Render Engine when exporting?
The FBX format exported by Blender does not have images included internally, even if you "pack" the images (for including them in the
.blend save file). Your best bet after baking your textures is to save them to real files on disk, so the exported FBX can reference them by name.
