then u make texture for a model
what color is transtarent ?

I cant believe no one answered this....

The transparent texture used in mapping is blue, you can find it in lots of the wads.

Or some of the new models use that orange. Im pretty sure when i say this, that any single solid color would work, you just must make it transparent through its properties.

The transparency can be any color as long as it is the last color in the palette.

can u use 3dsmax to make models ??
and what compiler shall i use ??
