Thanks esrael. I posted a few shots in the terrafusion discord. 

Hello, there are textures with alpha channel on some maps, usually used for cobwebs and grass. How do they do it? 

Textures in a .wad file, whose name begins with { and use the garish pink color(255?) of the Quake palette will, in engines that support the feature, be rendered as "alpha". 

... in my post!

https://quakewiki.org/wiki/Quake_palette 

These are called fence textures. You'll want a texture in your wad that begins with a bracket "{". Here's a wad with a couple of grates:

1. make a brush
2. make that brush a func illusionary
3. apply the skip texture to the whole brush
4. then apply the fence texture to just the faces that the player will see
5. use clip brushes to enable collision on the brush if needed. i.e. walking on a grate you would want this.

My map from jam 9 jam_dumptruck has an example. It's in the map source folder. The grates are near the info_player_start (map requires Quoth to play.)

Good luck! 

Since I'm so full of fail tonight a third, and final(?) post on this!

In editor create a brush, apply a "skip" texture to the whole brush then select a single face and apply your "alpha'd"(cobweb) texture.

Now, turn that brush into a func_detail_fence or a func_detail_illusionary(non-solid) and add a key/value pair of: _mirrorinside "1"

This requires you to use ericw's tools for it to compile correctly.

If you need any more specific help than what I have stated... ask away. 

Thanks to all. It's amazing how helpful this community is.

Does vanila Quake have grates/fences textures? I'm asking, 'cause I don't recall it to, and default wad has none. 

It does not, and vanilla Quake doesn't actually support alpha-masked geometry textures, only 2D elements (HUD and sprites)- one of the few if any objective steps backwards compared to Doom. 

Why they is black? How fixed it?

It's in quakespasm.
In fitzquake normal light, but for this monster only.

I think because they stand on func_train. In the air, far from surfaces, the monsters are also black in both engines. 

They are lit by the point directly under them. Either add a light source on the ground below inside a black func_illusionary brush or possibly add _minlight to them. 

I have a brush of the sky that the floor is made of. I made the bottom surface with a different texture. It returned normal lighting 

About 16 thick and 16 above the floor with a normal texture. 

there is a TF channel https://discord.gg/3zgJQ 

I'm wondering if there is any way to set it so when a level is started, it plays a song from quake, I know there is a property for entities called "music" but i don't know what to use the property on if that is what you use for the music

Also, i have the music files working in the normal game 

Add a sounds key to worldspawn with a number for the track you want.

sounds | 3 

 

I've been working on a death match map that has moving parts, I've noticed that for some reason, things aren't targeting properly. I have 2 moving doors that both use buttons, one of the doors has the targetname da1, with a button targeting it with the target da1, then I have a door with the targetname db2, and a button with the target db2, and what happens is one of the buttons doesn't open a single door, whilst the other button opens both! I need some help. 

This is a very common issue. By default, Quake groups doors which are close by into a single system. If you want to opt-out of this behaviour, you can add the DOOR_DONT_LINK spawnflag (3rd tickbox, numeric value 4) to each of the doors. 

 

I have another question, why do item_blank entities go through the floor sometimes?
