The Summer Members of the Season Nominations are here!
I don't have time to make a preset, but I can give you an advice. Open the material file in notepad and add a "scene_blend alpha_blend" above the "texture unit" line (without the quote marks)
material preset_12_eyeMatR{ technique { pass { cull_hardware none cull_software none scene_blend alpha_blend texture_unit { texture preset_12eyer.jpg } } }}
