hey guys, more advaned questions now.

Id like to replicate natural skies and lighting, i don't care for clouds, all i want to get is the blue sky and lighting.

Here, look at this, you can see that it looks like the object is outside on a lovely day with the sun shining into the object from the left and casting shadows..

And here, the sun is setting so the sky is a little darker and the shadows more.

Now i think thats really nice.. I really wanna use it, any ideas? He uses maxwell, but im sure this stuff can be done in Vray (Which i have and love)

Here are more images,

yup it can indeed be done with vray...

what you need to do is, create a direct light, and give that light a slight yellow tint on the colour - or a stronger tint if you want more 'sunny' sun you'll need to play around with the lights settings too. change the shadows to VRay shadows and also maybe go into the VRay Shadow rollout and make them an area shadow and smooth them. also click 'overshoot' in the direct light rollout so that the light covers your entire scene.

now in your vray parameters turn on the 'override max environment' box, it should be somewhere down in the environment settings or something i cant remember. keep the same shade of blue.

copy the values of that colour, and then go to the MAX environment panel, and change the background colour to the same shade of blue you have in the VRAY override environment.

now turn on global illumination, and just turn the primary and secondary bounces up or down till you have your scene as bright as you want it.

NOTE: you can adjust the vray override environment colour and direct light colour in order to get whatever effect you want. the above should give you something like http://img128.imageshack.us/img128/2660/gr...emaxwell6gy.jpg

its really nice though isnt it i love using this technique it gives everything such a realistic touch.

anyways with reference to the final image you posted, you cannot use volume light with vray but if you need to use volume light post here and ill write it out for you, im not gonna waste my time writing it all out if you dont need it
