Hello Everyone!
My question to you today, is:
How do you make an object (Plane)
transparent? I am having a tough time
trying to do so, and it’s a very big deal.
Thanks! 
Make sure you’re in textured mode. In materials change transparency to whatever value you like, .5?
If you are using GLSL, then just apply a material to the object, enable transparency on the material, select z-transparency then adjust the alpha value.
If you are not using GLSL, then I’m not sure how the engine handles transparency.
Hey, thanks man! 
I never noticed the transparency tool there before!
By the way, I used this to make a fog effect. I just put it in front of the camera
and it looks foggy.
