Okay, so I just hate the burning archer model. I hated it back in Classic when it was a pink skeleton (although there was a neat hidden skeleton archer on fire), and I hate it now when it's a low-poly hd pink skeleton. The silly spikes of the bow, the oversized pauldrons, the 2000x2000 low-res textures, everything. So I decided to make an actual optimised burning archer to replace the original model. (I've also done a similar thing with the wyrm, link below)
I've uploaded two variants:
-to import the standalone version, you just need to import it along the portrait and the diffuse and emmissive textures.
-to import the replaceable version, you need to import the portrait, diffuse and emmissive in the path: C:\Warcraft III\_retail_\units\creeps\burningarcher. The icon should go in C:\Warcraft III\_retail_\replaceabletextures\commandbuttons and the disbtn in C:\Warcraft III\_retail_\replaceabletextures\commandbuttonsdisabled. If you do that correctly, you should stop seeing the shitty pink skeleton in WE.
