Quake [Glass]

[Max_Salivan]

hello all)

how to make glass in quake?

if not difficult, give me instructions please :3

[Nahuel]

what engine are you using?

[Baker]

For an entity, like a door or lift or monster, add "alpha" "0.4" to it (you can do this in the map editor or in QuakeC).

With FitzQuake 0.85 and similar engines, the effect with take place automatically without QuakeC if using the default protocol 666.

For engines like DarkPlaces, I think you have to add a .alpha field in the QuakeC (defs) AND set the entity alpha like above. Transparency is not a feature of stock Quake, but it is supported in a number of engines.

[If this is what you are referring to ...]

PSP Kurok Engine or i can use Pro Quake,but sounds on this engine in 11 khz...(kurok 22khz)

The above answer doesn't apply to any of the PSP engines.

None of the engines have entity alpha coded into the rendering, so it really can't be done.

(Mostly because about the only mainstream mod to ever use "glass" was Nehahra until somewhat recently.)


A way to maybe fake it in a PSP engine would be to use a texture like with the name starting with *water and then setting r_wateralpha 0.5, since the PSP engines do support water translucency. The texture would need to be a single color, otherwise Quake's water warping would be noticeable. Only 64x64 texture sizes would work for such a texture.

oy yes,fake)
but what about this?

If you just want to be able to break a window (and don't care if it is see-through), that QuakeC you have there will do the trick.

I do not need to break the glass)

i need a glass)

and i dont know how to do it((

[Max_Salivan]

r_wateralpha 0.1 give nice fake glass)
but it is moving:D (waaateer)

Knowing you would ask that question, I time travelled to the past and told you how to avoid that a few posts ago

But alas, I failed proving once again you can't change the future. For reference, what I think you might have missing was ...

The texture would need to be a single color, otherwise Quake's water warping would be noticeable. Only 64x64 texture sizes would work for such a texture.

[Blackstar1000]

Hey guys. I figured out how to do this about a year ago and have since forgot. I'm using Clean QuakeC. And am using the quake modified worldcraft. I did it originally using qc I think.

Could you point me at the exact file that holds these material properties? I remember it being a pain to find the first time?

I guess what I'm asking is to please be more specific.

[r00k]

What Baker is saying is that, in your map editor, create a brush, select it then create a func_wall, func_illusionary, or func_whatever, fromt hat brush, then depending on the editor, (i use BSP), change the parameters for that brush to include
keyword alpha, value 0.5. This will make that entire brush transparent in FitzQuake, (hmm note to self fix this in Qrack). No QuakeC required. I just double checked and in FitzQuake 0.85 it worked.

[Nahuel]

In darkplaces you can get nice effects for glasses with simple shaders

The above answer doesn't apply to any of the PSP engines.

None of the engines have entity alpha coded into the rendering, so it really can't be done.

I'm almost certain i remember seeing transparent, breakable glass in default Kurok PSP. I'm sure it was done with a combination of engine and QC, but none the less, i think the PSP can do it.

[frag.machine]

Poor man's fake glass: use a oriented sprite. Will work even in software DOSQuake.
