heres a basic fire and ice cinematic render (really nice…), and i was wondering, how would i go about getting an effect like this in realtime?
the models arent a problem, just the render is what im talking about. thanks guys!

at 1:00, you get a similar effect here in realtime, how do you make the shadows cold and the light warm???

Looks like what you’re seeing is indirect illumination / radiosity. The warm/cool effect is due to the sunlight being warm and the skylight being cool. The skylight hits everything, but where the sunlight hits, the skylight is totally overwhelmed by the brightness of the sunlight. To get that kind of interaction amongst the colors you’ll need to do an HDR render with tonemapping. Looks like some bloom is also going on in the top one.

could you please describe hdr render and tone mapping?… i know what a skylight is, thats wherever there isnt occlusions, you add cool light, and the direct light is warm, ill just try that and see what i get.

here the skylight is set to green blue, and the direct light is orange, i could play with the colours some more, but what else does it need?

wow, i added coloured materials back and the effect was astonishing!! cool!!
just subtly bluer shadows than direct light really looks good.

edit…

Is it possible for you to share this model Rouncer? :wub: :wub: :wub: :wub:

hey i know its good, but its just the greeble modifier in 3dsmax on some low poly geometry… i *could* make it myself, just the render really makes it sing! :) youd be suprised on what that render could do for my models.

I see that! One thing that catch my eye is the sun is brighter at the far back than in the front! Do you know why?

I would like to have that obj or whatever format it’s in because I’d like to test my lighting on it see how it compare to your screen shot, because your is awesome!

Specular (even “dull” concrete surfaces have some specular) - and in particular the Fresnel effect makes specular a lot brighter at glancing angles, which I think is mainly what’s causing that.

Make sense! Thanks Reed.

Another thing that I don’t understand, why is the blue from the sky showing on the surfaces so much? I don’t think this happens in real life does it?

Sorry Rouncer, it’s off topic and not answering your question :rolleyes:

it does, but the effect is enhanced in renders for because it looks nice. (its the ground reflecting the blue sky, with radiosity)
