problem with see-through objects

[Sabotuer [Q2C]]

I have this texture that is part pink, which is supposed to make that part invisible but I can't make it invisible, it just becomes black, unless I make it all a trans33 or trans66 but then the parts that aren't supposed to be see-through are!
Help!

sounds like the "pink" might not be the exact right color....
Are you positive that it is the Q2 transparency color or does it just resemble it?

There is no actual way to have a true transparency in the Quake2 - vanilla engine.

It sounds like you are going about the process correctly and the results you are seeing is about as good as it gets.

The "pink" color is texture #255, in Wally that would be the last texture in the palette, bottom right hand corner.

yeah, it's correct. the transparency color in vanilla Quake 2 only works in OpenGL mode, when the brush is set trans66 or 33.

this means that the parts which are supposed to be visible are drawn fullbright and are transparent too.

and still, it is possible to get some nearly convincing results, regardless all these restrictions.



here is what to do:

a)
the transparency of the visible parts is less obvious when you see two sides in a row.
so make the brush for the grate 1 unit thick and set also the mist flag. then both sides are visible. when the brush is solid only one side will be visible, and the whole thing will look much more transparent.

of course you need also a clip brush then to prevent falling through it.

b)
it is still too bright. so you may do some image processing. make the texture a bmp and load it in your preferred graphics editor.
use gamma correction and make the texture A LOT darker, so that it will look halfway right in your map, even if it is shown fullbright.

then convert it to the Q2 palette again and of course don't forget to fill the invisible parts with color 255.

if you do it right, the grate will look nearly as good as in Quake III Arena.
here is an example map:

thanx mates, I'll try that!
And yeah, it's the right colour. I don't think evil does anything wrong in his texturemaking

It sounds like you are trying to make the individual faces of a poly be transparent and others not. Am i right?
If so...you can't do that. Like seeing into a box(poly). Making one facee transparent and then seeing into the poly to the backside of the other faces. It doesn't work that way. You would have to make the poly hollow(therefore making it into more polys for each side) Then make one of the polys that make up a side transparent.
If i am not htting the nail on the head...just ignore what i have written.

yeah I know, I just used the Grieve way
