I noticed there are textures in Unity for AE2 but since the latest AE2 for 1.10 switches to lowercase names, its textures in Unity don't work.

While I'm not certain I managed to change every single texture's name over to the new format, this is what I've been using myself. Might have missed a few items and blocks, also didn't bother with any of the parts, and particles and such since it seemed that Unity's were the same as default textures.

I'm assuming I'm allowed to upload this? Here it is: appliedenergistics2.zip

Closing, duplicate of #110. Will be fixed soon.
