Hiya.

In Unity theres a lot of shdaers that use the alpha channel, for example, using the alpha channel to define which areas are specular on a diffuse colour. However when we use the same textures in cheetah, any area black in the alpha channel is invisible, and checking /unchecking the use alpha channel box at the bottom of the materials properties window doesnt seem to actually switch any alphas off (on the main colour tex).

the solution is to delete the alpha channel but that damages the Unity side of things. We can make a different set of textures for each environment but that is potentially a bit of a time waster.

What I wish for is for a way to switch off alpha in the main colour tex property.

In this pic, the visible parts are bits where the textures have a specular property. The invisible parts have nospecular property. You can see how it makes it more difficult to work on this in Cheetah, when its invisible.

Thanks
AC

Argh...Just to reiterate, this is killing me today...

Simplified;

we need alpha channels on our colour textures for unity.(sometimes for actual alpha, sometimes for specular highlights)

We need a checkbox in cheetah so we have the option to thoughroughly ignore these and render the texture as if it has no alpha at all. Otherwise it renders as invisible. Pretty please?
