Well, Now I have Vue's demo, I start can to play... And, like all the vue4 users I think, I start to play with volumetric lights. And then, it looks like the sun light don't project volumetrics beams and, in consequence, volumetric shadows... Is there something I done wrong ?

I think you can only get the beams if the sun is in the camera view. I got good rays when I was using the beta, but only when the sun was in view. :) Laurie

If you want the sun to project volumetric beams, make sure to select the sunlight and turn the 'volumetric light' on. Two notes about doing this : - When the sunlight is volumetric, the light intensity is controlled by the 'intensity' slider in the volumetric panel. - It is best to not mix too many volumetric things together. Do volumetric atmosphere OR sun OR materials... separately. Now... you will have a better control of your scene if, instead of making the sunlight volumetric, you add a volumetric point light to your scene instead.

I did some tests after the last post. - I found it difficult to get volumetric rays from the sunlight. Better to go with a spotlight made volumetric (not a point light) - Turning 'dust in volume' and 'shadow in volume' give a better texture to the result.

Assuming you have all your volumetric settings correct, its still a bit like the real world - how often do you see beams of shadow streaminig off the top of mountains at sunset? I find I have to play with settings a lot in order to get volumetric sunlight shadows - don't expect to see them against a bright sky for instance. Also - size IS important. How muck volumetric shadow you see depends on how much 'dust' in the atmosphere the rays travel through. I did a test where I placed a terrain in position to get shadow rays, but got nothing. I then enlarged the terrain, and moved it away from the camera, so that it looked the same size as in the first test, but in reality there was lots more 'atmosphere' between camera and mountain, and got lovely volumetric shadows. Fiddle about.

Thanks Laurie, I am envious that you are a beta-tester for Vue... it must be really cool ! Have you got some exclusive news on Vue5 ? ;-) Thanks, Agiel, I did what you said and obtained good results by making a plane blocking sunlight and putting a point light... and very funny : I am doing a scene with an 'Angel of Victory' like the one you joined ! And thanks zoon... making some tests show me that large size scenes are better for volumetric sun light. Your gallery is incredible... I can't believe that some of your scenes comes out from Vue2 !

heyas; dont you have to make sure to turn on the volumetric atmosphere to get a volumetric sun light?

You simply can't put volumetric sunlight if volumetric atmospheres is not turn on...

heyas; okay, that's what i thought. then thats not the answer. :) but at least i was right....
