Thanks for your support! As for now I hope this thread can attract other people that are figuring out the editor. 

As for the questions, I do have some:

1) When you create a box mesh, how do you separate it's surfaces so they are not connected to the rest of the other surfaces (if you want to subdived/split quads but you don't want the rest of the box to be affected by it)

2) What are the best shortcuts to make spheres, cylinder and round shapes?

3) How do you set scripts for moving meshes like doors, moving platforms or pistons?

4) How do you expand the grid subdivision to not being limited when you make? Right now it is stuck at 64x64 and it's a bit limiting.

looks great 👍 and exporting and lights seems to work too, nice👍 

these look really good 👍

I'm interested in anything that can crash the editor (it shouldn't happen - and by the screenshots it seems you didn't go over any limits either) 🤔
(if you got any map that can crash it please upload it somewhere or just send them to me: mutantleg(at)gmail.com )

I'm afraid that is beyond the engines capabilites 😔

you can make prefabs though:
- select a bunch of entities
- enter console command: SP  [prefab name]
- now in menu option 3 (props)
- you can add them in with a little menu (hold Q or E) 

prefabs are just little maps (.xtmap) themselves so you can edit them or add maps manually to the    quadmacro    folder

I wanted big levels too - the prison was planned to be a giant complex taking place in more than one levels
(it still is but .. well mostly in my imagination) and I was worried that E1M1 was too small and in general people will
just whizz through the game and going to be made fun of for it ..
but turns out  for most people even this little first map was an incomprehensible maze 🤔

for the next engine evolution I want it to have better optimization for multi-story levels (e.g. right now the occlusion culling is 2D only)
I guess that also means larger levels 🤔 but I don't have hubs planned (mostly because I don't want mandatory backtracking like the Q2 hunt for the powercubes crap - and I just don't have the resources to make a bigger game)

1)  flares

create a regular light
select it
use the console command: FR 64
(FR stands for flare radius and the number you write will be its size)
you can change the sprite with the command: MT  f5
where f5 is the sprite name  (possible sprites are in the  Zortch\editor\spr9   folder)

2) key behind glass

 this is an engine limitation - it only checks if you hid the key behind energy doors
only possible solution right now is to make the container bigger so you cannot touch the keys radius
sorry about that 😔

3) green reactors
you actually found a hidden cut feature
(it was another sort of reactor for a different room)
the green reactors you can find within the actors:

wgen is the wall generator
xgen is the large green generator

4) skybox

if you are using preview map (with play command) these await a patch for to be tested
if you using already the custom maps let me know (it might be an error if they don't work)

5)  sparks and smoke

these are also actors
you can find them in this row:

they meant to look like little arrows to show the effects direction

let me know if you need more help with any of these
for the skybox I  possibly still need to make a patch

sure thing:

(first of all, for anyone else who is interested or don't know how to place actors yet:
- press 1 to enter actor mode
- hold Q to show the list of actors (click on an icon to select one)
- hold E to place actors  (click on the world to place one)

you can find the lights in two places in the actors list:
from bottom the second row in the all tab

but I recommend switching to their light tab, where you can select radius and color:

after placing one you can change its radius with the R console (~) command: e.g R 3000

to change their color use menu mode 4
(works same way as placing actors, hold Q to select and E to assign)

to make an ambient sound:
- press V and draw a zone
- enter mode 6 (properties) and select ambientsound
- use the console command NAME to set the name for the sound

names of the ambient sound can be found in: data3.dat\data3\sound_dyn\
(data3.dat is just a renamed zip file)
some examples:

ambcave
ambcomp
ambgas
ambhum
engineamb
escamb
fanloop
spooky1
spooky3
turnamb
waterfall

1) cylinder pipes
there are two ways
one is to extrude one end and scale it down and extrude again
you can extrude selected quads by pressing K or L
to scale use the console command: S
e.g. S 0.5
is scale by 50 percent

another method that is easier but results in messy geometry is using csg:
this also uses  console commands:
- make two cylinders (make sure one is in the another and they overlap)
- select the first and use the command:  OP1
- deselect it
- now select the second and use the command:  OP2
- deselect it
- use the command: SUB
now there should be a hole in the first in the shape of the second

there are also other operatiors that work the same way: SUB ADD INT
SUB  is for subtract
ADD  merges two entities
INT  is for intersect (if you make two rooms or hollow meshes you can contact them with this)
(also you can make meshes hollow with the command FLIP  )

2)  joining meshes:

- select one mesh
- press J
- click on the other mesh

3) doors:

in properties (6)
select 'usedoor' or 'keepdoor'
for triggerable either use 'trigdoor_stay' or 'pathvator_togg'

4)  fog:
one fog is the dark prisonfog
for this you need to place the actor 'spec_darkfog'
it's in the top row above the brainsucker statue
and looks like a little monitor

another fog is the sprite fog:
- make a zone with V
- in properties (6) select 'smokebox'

5) scaling:
you can use the console command S 
e.g. S 0.5
"scale" also works: e.g. SCALE  0.5
this is uniform scale, if you want to scale on an axis,
you need to give 3 parameters e.g.:
SCALE  1   0.1   1
they are in the order of X  Y  Z
and Y is up

6) snow:
there used to be a snow effect in the game
but I need to check if it's still in  🤔 (possibly reimplement it )
I'll try to get it in by next update

if you need help or more details with any of these let me know!

1) hiding movers
I ended up using vertex colors myself
there are two ways:
- either set them manually in quad edit mode (they can be assigned in mode 1 vertex move)
- or select the mesh (make sure it's unique wiht Ctrl-U) and press Ctrl-B  (this should auto calculate them based on surrounding lights)

2) destructable walls
in properties select deco
(deco, decorock, decowood or decotri - they differ by what debris will look)
or explowall   (conveniently hidden under teleplay_silent)
they all refer to the same mover but explowall is preset for only explosion damage
by default a deco gets destroyed in a few shots or melee attacks
for a regular deco you can play around with the following console commands:
HP 100
sets the healthpoints to 100 in this case
ARM 100

by default a deco has 50 hp and 0 armor
an explowall is the equivalent of a decorock with 1hp and 90 armor

a bullet is about 20 dmg for mach and 10 for the shotgun - but can change if you got the powerup(8x) or play on easy(1.25x)

3) disappearing surfaces
this can happen by either the occlusion culling rejecting them
or they might be get optimised out by the editor
you can turn off optimisation for an entity:
in properties (6) in the Flags tab turn on the  noopt flag
or press ]  }      (or it's equivalent on your keyboard)

4) geometry staying
after unbsp-ing something rebuild the bsp
either use the console command: BSP
or press 0   
(if its still staying after this send me over the map because it's a bug)

if you need help with any of these let me know!
