icons

Ok thought this was done, but can't find it right now (heading out the door) importing custom icons
would it be make icon->convert to blp->upload to root in war3patch.mpq->change interface icon path on custom unit to icon-name.blp or?

1) Check the size of your icon. It must be 64x64.
2) Try to add it without compression.
3) Use the ReplaceableTextures\CommandButtons folder for enabled things and the ReplaceableTextures\CommandButtonsDisabled folder for disabled things (greyed). All the folders should be inside the MPQ. For enabled buttons, which should go into ReplaceableTextures\CommandButtons, use BTN<somewhat>.blp (<somewhat> replaces your filename). For disabled buttons, which should go into ReplaceableTextures\CommandButtonsDisabled in order that they work, use DISBTN<somewhat>.blp.
