Cloud solutions

[Alyosha]

Hello,

 

I've tried different solutions to create clouds and atmospherics, but each one of them has increased the rendering time at least by 100%. I've tried out dreamscape, vue and vray environment fog and they all chew resources like crazy.

 

Is this a normal thing to occur or am doing something terribly wrong? It doesnt seem logical to me that a couple of, albeit volumetric, clouds would increase render time 2-3 times, but that seems to be the case.

 

I expected at least vray volumetrics to perform better but they even increased it.

 

Has anyone had any experience with above mentioned? Particulary dreamscape?

You can try VRayComp Tex to create nice clouds.

just use cloud background images or comp them in post. if you want a more 'interactive' atmos, render a couple of zdepth masks and layer it on in post.

Yeah i'll probably do it standard way with tex, but i was just wondering about the 3d options, i'm really enthusiastic about building whole scene completely 3d, thats why i've been looking into this lately

 

but every atmospheric i try just creates crazy render times, does anyone know why? I mean for example vray alrdy does the environment and sun interaction, why adding a couple of volum clouds adds at least 2x render time???
