Those Q3 tech effects.

I've been wondering if those kind of effects were done in zDoom, or other modern sourceports. I'd like to make something like that, but i'm not fortunate when it comes to texturing/effects...

Here's a little video I've recorded in Q3 to make it clear: https://www.youtube.com/watch?v=21WmBmS5E9k

I managed to do the light, which "passes" through the texture from one side to another, but it's not perfect yet. What I'm really curious about is the electric effects. I'd like to have effects like those, as I make most of my maps Tech-based.
So the question is: Are there any resources which offer effects like those? I'm not saying that I need the same, but something similar, or anything that's related to tech design. I think they really bring "life" to levels.
If there aren't I think I'll have to learn some graphics...

Animate it onto a texture? You could always just animate the lightning bolt by itself on a transparent background and put it on a line-def behind the grate, using the scroll effect for motion.

Thought about that, I'm still trying to achieve this effect, I just wanted to know if there were any resources which contain something like these, or even a "lightning bolt" texture which I can animate. I still can't make decent art. :/

Well, one potential route is to try to make the desired particle effect in Blender and then make that into a 2D texture.

You should be able to achieve these effects with the hardware shaders in GZDoom. It doesn't seem to be able to pass two textures to a shader, but you can work around that, by putting both your texture and desired overlay effect on the same texture. Of course, you'll have to be a bit careful with the alignment, then.

I made a simple example wad, that should give you an idea on what's possible: http://88.198.197.45/boris/doom/shader.pk3

Was not expecting that haha.

Wow, never seen this feature in GZDoom before. Thanks a lot!

I played around a bit more and came up with a more useful example:

I posted a explanation and the example wad on the ZDoom forum: http://forum.zdoom.org/viewtopic.php?f=3&t=48834

Many thanks boris, I think I can do it now.
