Hi OhiraKyou,
I went through this step by step with our Blender specialist and we did not get to step 10 because at step 9 the plane reimported correctly and the material was applied. For further testing on your end, I’m including the files we generated from Blender.
There are 4 files: 2 exported with the ascii exporter and 2 exported with the standard fbx exporter. Each pair includes “NoUV’s” and “WithUV’s” Please try these and see if you have different results.
