hi doing some basic test…i ran into lighting problem…or perhaps i just dont know whats happening…

so i made a empty room in sketchup… did a livesync. just to test out artificial lightings ie; point light, strip, rec, etc.

so everytime i place 1 light source inside the room the room gets lit - up! which is fine…
but after few seconds it will start to fade out to complete pitch black… as shown in my screencapture…

when i try to edit parameters of this light (rectangular) for this case…it will lit-up again bright then after that will fade out to black no light source again even tho i have the light source…

still in the learning curve so forgive me…

thank u in advance guys.

:pray:

Hi @xrowdac2,

Just to confirm, did you turn on the ‘Auto Exposure’? In closed environments with dim or insufficient light, Auto Exposure will automatically adjust the brightness of the light source.

i left it in AUTO (switch ON) did not touch it…

i also tried other types of lightsource rectangle after placement it lits up…properly then few seconds later it dimmed down to pitch black… again…
:thinking:

Try to put light near to the wall or input bigger value in Attenuation Raduis
