I've looked, cannot find any reference to this exact issue anywhere. It's not the usual RTFM, as far as I can tell.
Background:
MC 1.4.7 on a custom modpack server outside my control (thus not upgraded to newest forge)
I have a custom arrow that works great. All the usual issues have been dealt with. It's fired from a custom bow.
In Eclipse the mod works as expected.
The arrow texture resides in a /gfx/ folder in my mod along with the other textures my mod uses (blocks/machines, items, etc...).
After recompiling and reobfuscating the mod, I copied the gfx folder to the reob'ed directory and put everything in a zip.
I deployed the mod to a tekkit-lite instance for testing.
Now the problem:
All my textures are working EXCEPT the arrow texture for the EntityArrow. It is located in the same folder as the items spritesheet, and other textures. I get the "Texture Missing" texture on the arrow in-flight instead of the custom texture. Again, the textures work fine in Eclipse, but not in the deployed mod.
I've checked that the folder is in the same location inside the zip as it sits in the eclipse src folder
I've checked that the image is not corrupted
Ideas? I'm lost at this point.
