Q.&A. Thread

I thought I would start a q&a thread for those who would like to know more from those who do!

First ?:
How do I set up a terrain texture that uses alpha mod brushes to blend from a fully visible texture to a invisible texture(empty)?

All you need is alphaGen vertex in the texture stage of the shader for the terrain and an alphaMod brush placed over select vertexes of the terrain brush.

Okay I have a question. How does the "move into entity" function work in GtkRadiant 1.4? It sounds like you can use that to add a brush to an entity, but I'm not sure if that's what it does and if it does, how exactly does it work?

You can group a brush to a previously made entity by selecting both and then choosing "move into entity".

Is there a way to use a seperate texture as a alpha channel in a shader w/o the cutout adding brightness to geometry behind?

Should rename the thread to "Ask Obsidian". I like.

@Theftbot, have you read sock's great article about alpha blending?

You can use a texture's alpha channel for depth testing and then make it invisible in a number of ways, alphaGen const 0, for example.

Note: As with every multi-staged shader, each additional stage multiplies an extra rendering pass.

Also, a Q&A thread seems redundant for a forum since just about every single thread is a Q&A... just saying...
