so i have been playing around with the worldspawn settings in my map and there happen to be weird spots of light (didnt put any light in radiant there :O) and also the normal maps are alot more intense.
please help i cant se myself fixing that :O

Use some stock worldspawn settings from another map if you've messed up the lighting in your own, then just make minor tweaks here and there to change the appearance. The weird lighting "spotlight" effects are usually caused by a lack of ambient lighting and/or direct sunlight so try adjusting those values a bit until the lights go away. Also ensure your lightgrid is properly set up as well as reflection probes in all the right places.

ty well the lack of lighting should be the problem but that would make it nearly impossible to create a entirely dark map wouldnt it?
also whats causing the textures to go all that weird?

the wordspawn didnt seem to change them

reset the worldspawn settings and in map.gsc add setdvar("r_contrast","yourvalue"); and setdvar("r_brightness","yourvalue"); to adjust the lightning in your map

Don't use any textures that end with the suffix _wet in Radiant. They appear splotchy in-game.

ok i managed to fix it by changing deffusefraction to 0.2 instead of 1 i dont even know why i did it that way 
btw another question is, if it is possible to have bright light outside but everything inside being really dark. the way i tried it (turning up the sunlight) just made everything bright

Youll probably want to set higher contrast. That helps a lot if you want your map to be bright outside and dark inside.
Add setdvar("r_contrast","yourvalue"); to your level gsc file and lemme know if it worked (1 is normal contrast and max value is 4) I would prefer setting it to 1.2 or 1.3
EDIT: Or make a custom vision file using the tutorial on the wiki. The only value to set will be r_filmContrast or something like that and it probably behaves the same way as it does as a console command
