Hello guys,

Do you have any idea how to set the air absorption coefficient. Is it safe to set 0 for a typical case? Also in my case, the air pressure is very low and temperature is high. Is it still safe to set 0?

Thanks a lot!
Eric

Hi, I have exactly the same question if I set the absorption coefficient 0,2, it affected the temperatures quite strongly, so this value seems to be quite important...

hi guys,
I want to know how variation of ambient pressure will affect absorption and scattering coeffiecients of air.....please reply as soon as possible
