Question by jussavin · Dec 07, 2011 at 09:55 AM · shader

shader that uses separate diffuse, alpha, normal and spec maps

Hi Unity community,

I'm new to shaders and have been experimenting but can't find or figure out how to create the exact shader i need. I need a shader with seperate diffuse, alpha, normal and spec maps so that i can switch out the main RGB texture without affecting the alpha cutout, bump or spec maps.(having spec maps isn't too important but would be nice). It does need to cast/receive shadows though.

I've used some shaders that have the Main texture use the built in alpha mask, but when i switch out the texture it also switches out the alpha mask (as it should). Would it be possible to add a texture to the main texture without replacing or affecting the alpha channel?

Any help would be greatly appreciated =]
