Q.&A. Thread

[Theftbot]

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)?

[obsidian]

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?

[obsidian]

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

[Theftbot]

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?

[cityy]

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

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

[obsidian]

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...

[fKd]

this is like a new tv show, q&a with your friend obsidian. todays guests include, theftbot, cityy and eraser.

[GONNAFISTYA]

And the show will segway into commercials showing all the times I ruthlessly tk'd obsidian in ETQW.

I started playing ETQW again, I'm still pretty awesome.

[fKd]

loved the beta, but for some reason over here the retail version never picked up. sucks, but shit. the w:et server still cranks.

[obsidian]

That's because GONNAFISTYA made them all ragequit.
