Alpha textures on model?

[Princess Luna]

With me being somewhat new to model ripping I have a question as to rather or not these textures shown in the picture below are either Alpha layers (mostly referring to black textures where the fire and wires are located for transparency) or if its just extra texture material. P.S. This model of Rez came from Gex 64: Enter the Gecko USA port for the N64.

file-native opacity settings are rarely supported by 3d modeling programs, so an opacity map is needed. an easy way is to set the texture's brightness to 100% and saturation to 0% (to get a completely white semi-transparent texture) and place it over a black layer. thus, an opacity map is made!

they are actual textures, they just have an alpha channel that isnt supported, making it opaque.

Ah I see, now for this opacity map. Can this technique be achieved in Blender as well or is it just 3DsMax?

It's possible that the game uses a separate texture as the alpha mask instead of the usual alpha channel. Simply look through the textures that were ripped with the scene for a greyscale image that resembles the fire/wires. If you can't find one, it's possible that the images are done using an additive effect.

Thank you, once I get home this weekend from family, I'll search through my VRML folder and upload the texture files here to be sure its the one your specifically talking about before any editing begins.
