Shadow details

[zooropa]

Somebody can tell me why my pre pass shadows are more detailed than my final render?

Thanks

Re: Shadow details

... because your final pass is brighter and hide the shadow.

Re: Shadow details

I would set a lower GI environment intensity - it's a question of the adjustment of the lights, the ratio between soft and hard lighting.

Re: Shadow details

Provided that you are not clamping your output (and even if you are really), you should get in the habit of making sure you're lighting intensity is not overly bright and balanced. V-Ray takes much longer to calculate very bright areas, so managing brightness is a means to keep rendertimes down. I personally don't advocate clamping scenes, but there are cases where that just may need to happen. If you're not clampping, then you should really try to get backgrounds at just at white or just over white. Its very possible to have values that are much beyond white (@ 1.5 or even greater) and having many of those values in a render are going to make it slow down.

Re: Shadow details

Here is my final work, i still want to retouch this because i think it might useful for future experiences.
Thanks Micha and Dalomar, Dalomar, can you explain me what is "clamping" or where i can find this concept.
Thanks!

Re: Shadow details

V-Ray can calculate values that are brighter than white, so all that clamping means is that there is no information calculated that is beyond white.

Thanks Dalomar, do you know where can i read more about clamping?
