.roq videos as textures

[pollo]

Hi all

Would it be possible to use .roq videos as Radiant textures? Kind of like the water texture, but instead of deforming the texture, somehow play a video on it. I've been searching and apparently it's possible in some Q3-based games like Star Wars: Jedi Knight, but I'm not so sure about cod2 (although it's based in q3). As I read it has something to do with shaders, is it possible to implement such custom shaders like this I post below in cod2? If so, know any good resources I can take a look on how to do it? Would appreciate it

P.d. I saw there are shaders in the materials folder, but how did they make the actual material file that is used in radiant and is "linked" to the shader which animates it? I see no option in asset manager for that (I mean, I can make the texture but how to link a custom, or even a stock shader?)

Thanks in advance

    }
    {
        videoMap video/openinglogos
        alphagen const 0.25
        blendFunc GL_SRC_ALPHA GL_ONE
        glow
    }
}

You can play .roq files, like the CoD2 intro sequence when you first start the game, but only fullscreen.

You can use atlas-textures to play 'videos' or more gifs.
However you have to export every frame of the video into such an atlas texture.
I've done it with something like 144p resolution or even smaller, as these textures grow really big really fast.

It its possible - yes, but not really practical.

Yeah, I know it is possible to play a full-screen .roq video and back in time I used a similar technique of playing gifs, exporting every frame and playing with hide() show() in script (maybe you mean the same with the aliax? ).

The idea is to play a .roq looping on a surface, eg. make a case texture similar to the water one, and somehow with asset manager, link it with the shader above that plays the .roq video in-game. Because as you rightly say using a lot of images is unpractical and makes the map fat.

Thanks for the reply

I think I kind of remember now.
It was done as an effect, not as a texture, so placing and scaling can be abit tricky.
Lookup how smoke or fire effects are done, they use an 'atlas'-texture, something like this:

You basically have to export your video clip into this format and fiddle around in the EffectsEditor to display every frame.

Ty for the clarification I will try doing that. Any other knowledge about this is welcome

Any quick n dirty "howto" on these atlas textures?

Sorry, my first reply was misleading.
I have done it using an effect and placing this in the world, not a rela texture.

I've played with CoD2 shaders several years ago, the only thing I managed to get to work was changing the speed of the scroll-texture on xmodels, as far as I can remember. Not even the yellow-pulsating glow on objective-textures changed colors. I gave shaders a couple of hours/days to try to modify them and getting the CoD engine to accept them, but I did not 'understand' them well.

CoD4 got those TV's that display a short video, I remember recreating these without much success.

add a anglestoup(origin1.angles) at the end of your playloopedfx:

		playLoopedFx(level._effect["dog"], delay, origin1.origin, dist, anglesToForward(origin1.angles), anglesToUp(origin1.angles)); 
	

That should fix the upside down stuff.

[pollo]

yea I tried it too but still the same :/

[IzNoGoD]

What about using this instead:

		playLoopedFx(level._effect["dog"], delay, origin1.origin, dist, anglesToForward(origin1.angles), (0, 0, 1));
