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
