Creating a working mirror

[Vartex]

Hello there JKHub.

 

I recently ran into a problem when I was working on my map. I tried to create a mirror using "system/mirror1" and "misc_portal_surface" entity placed few grids away from the mirror plane. But when I try to try the map in game, I get a missing texture at the place where I put the mirror.

I would be really grateful for any kind of help.

 

This is how the mirror looks in GTK

 

 

 

And this is what I get IG

Not sure how old this engine is but maybe you need to build cubemaps?  I dunno xD

I am absolutely happy. Finally I got my mirror working. I don't know what I did wrong, but I got an answer from Raven and I just set the mirror up as written in the mail and it works.

Reading that some other ppl are having problems to get their mirrors working I'll just paste the mail:

 

-------------------

Set up the mirror just as you normally would in Q3...

 

1. Make sure the mirrored surface has a qer_mirror (or portal) surface

property (we had one in the game called mirror_floor2 in our

textures...)

 

2. Put a misc_portal_surface entity above the surface (around 16-32

units away is fine)

 

3. Make sure the surface is the only mirror the entity can see (it

doesn't like seeing more than one mirror at a time)

 

4. Make sure the surface to be a mirror is made of only one brush for

best results...

 

(our mirror texture has the following setup in the shader: 

 

textures/tests/mirror_floor2

{

qer_editorimage textures/tests/qer_mirror.tga

surfaceparm forcefield

portal

q3map_nolightmap

{

map textures/tests/qer_mirror2b

blendFunc GL_ONE GL_ONE_MINUS_SRC_ALPHA

depthWrite

}

{

map textures/tests/floor02_alphab

blendFunc GL_DST_COLOR GL_SRC_COLOR

}

{

map textures/kejim/env_newfloor_kej

blendFunc GL_ONE GL_ONE

rgbGen const ( 0.200000 0.200000 0.200000 )

tcGen environment

}

}

 

The forcefield parameter makes shots bounce off of it

 

The portal parameter makes it show a reflection

 

the other texture (tests/floor02_alphab) used on it gives it a texture to

show (with an alpha value), just remove this if you want a true mirror...

 

and the last texture in the setup gave it a shiny environment map like a

piece of glass...

-------------------

 

As already written, I don't know what was wrong with my first setupsd, but I think it was the wrong mirror shader. Now it works just fine.

That post is in the JO section and if I remember right the mirror shader doesn't work quite right in JA, if you play the JO demo the final duel areas entire floor is a mirror.

 

Gonna have to call in the big timers, @@Szico VII

Oh well, I tried...

Do you have the shader in a PK3? If not, do you have sv_pure set to 0 - the game won't try to load your shader otherwise.

I found myself similar tutorial, but it was no help with the JKA's mirror1 shader. Is it possible that came with base JKA is broken? And I have to download a new one?

I had the shader in pk3 when I was making this thread. Although when I tried putting it out from the pk3 and setting sv_pure to 0 it was no help as I got the same result

Shader:

 

 

 

textures/mapname/cameraportal
{
	qer_editorimage	textures/mapname/cameraportal
	surfaceparm	nonsolid
	surfaceparm	playerclip
	portal
	q3map_nolightmap
    {
        map textures/mapname/cameraportal
        blendFunc GL_ONE GL_ONE_MINUS_SRC_ALPHA
        depthWrite
        alphaGen portal 2048
    }
}

Great finally! I spent ages trying to get this thing to work!

Thanks a lot Boothand.

Is it possible to use this on playermodel textures?
