Title: How to cut out clouds properly to a layer?
Post by: KirillK on April 20, 2012, 03:01:57 PM
Is it still necessary to render clouds two times: with the atmosphere and without, to cut out clouds properly onto a layer  or maybe there is some other trick ?

There are a few different ways you could approach this, but they all involve at least 2 renders at the moment. I'm going to try to figure something out for v2.5.

Hello again,

I haven't been one to release too much teaser info, but I just want to follow up and say that I've got this working for Terragen 2.5. You'll be able to output separate cloud and atmosphere elements from a single render, with only a small increase in render time. This is part of the Render Elements system for Terragen 2.5. Actually we currently have a total of 23 different render elements that can be saved from a single render! This allows incredible flexibility for relighting and compositing after the render.

We don't have a release date for v2.5 yet, but it will certainly be this year.

23?? Wow, considering the amount us testers already have now that's quite an increase :) Great to hear, bravo!

Yes very nice news indeed  :)

Is this what is called a z-pass? From what I understand, this sounds better than a z-pass. If not, can terragen do a z-pass (perhaps by another name?)

I am asking because I want to try some more complex compositing with my renders.

z-pass is usually analogous to a depth map, which TG2 will output in version 2.5, along with a ton of other types of render elements.

TY Oshyan, sounds good. Hopefully I'll be ready to go by release time!

Hi Matt/ Planetside,

If you've got 23 (!) different render layers/ render elements coming out in v2.5, will any of them have the ability to output different populations to different layers for later post-processing?

For example, there's a population of tree species A with red autumn leaves and tree species B also with red leaves in the same image. It would be wonderful if we could separate out tree population A so that in post, if we wanted, we could grab tree population A and color correct its red leaves to yellow.

This could really be as simple as a user-defined (population or object) black-and-white matte layer.

We will hopefully have the ability to limit render elements to a particular group (or to exclude a group). I think that would cover your need.
