Cloud engine

[tom schuelke]

Hi Vlado,

Well, dramscape does make clouds, but the athmospheric effects are rather poor, compared for example with vue6.

what i would like to see most, was an implementation, where the real energy throug clouds could be used.

meaning floatingpoint, to get realistic shadows and so on.

i just tried to get this with vue, exporting skys to vray, but i only can get usual images.

What do you mean by "use the real energy through" the clouds...like a HDR with proper propagation of light that travelled through the clouds ?

From what you tried it sounds like Vue is not able to output proper float HDRs ?

Did you try TG2 Preview ? it is supposed to create proper EXRs tho i didnt test that.

the atmosphere looks pretty nice in TG2

Another possibility to spice up DS skies is using Afterburn together with DS. DS for high and not so dense clouds and AB to create cloud towers specifically where they are wanted. Can get tough to get it right the more far you get away towards the horizon (as max doesnt really offer a curved planetary groundplane :P)

Hi Thorsten,

well thats exactly what i ment.

I am able to output an hdr, but i cant get the floatingpoint to work, what i would expect.

in vue i can adjust this after an image gets rendered, but i am just new to vue x-stream, so maybe its only my problem here.

well what i would wish,

is that vue just would make vray a native renderengine...

vlado .. just couldnt you call them and tell them, mentalray is old ugly, unnessesary, ....

they have to use vray ?

Ah,

well , i just have taken a look to terragen.

It seems to be on the same level as vue...

impressive immages.. What i love in both of them of course is the ability to get very detailed athmosperic images.

if on could just implement this in a seamless slick interface to max-vray...

Another option might be the new major release of DS. They claimed some pretty nice stuff to be coming....They claimed it would come this year....but i got no idea if it will. As they got VrayGI to work with Fume i guess DS support for VRay should be better too in case of a new major release.

ah,

that would be great. lets hope for the best

here is a terragen to max importer: http://guruware.at/main/terImp/index.html
haven't tried it yet..

What about a connection between Vray and Ozone?

Ozone is just the atmosphere part of vue but inside MAX, as a plugin. Connecting ozone atmospheres with vray sun and sky system would be unbeatable

ozone, just like xStream is written as mental ray shaders, so that would be a re-write not an adaption or a compatibility thing. From a quick try it also looks as if it wouldnt calc with real world values, so basically you're stuck with max value of 1 wich is not really what was asked for.
