Title: Volumetric Light isn't working
Post by: Lorenz5 on 2018-03-26, 21:30:30
Hi i'm doing a scene that requires a volumetric light, however the volumetric light effect isn't showing?  I have made the scene to a realistic scale and the box that the material is applied to is not in the way of the camera I have done many adjustments but nothing seems to work. Below are images of the scene and the settings for the material. sorry if this is a noobie question, but I am a student and this is for an assignment.

Is the Absorption pure white? If it's 255,255,255 then no effect will show up - anything other than pure white will show an effect though.

I changed the absorption so that it wasn't pure white, but then the render went black?

That's because you set absorption distance to very small value. Increase it and you should start to see volumetric effect.

As he says :) With 10mm as the distance you are basically saying "You can only see 10mm into the scene" - this is where the use of real world scale in setting up your scene comes in handy :)
