Add Fog raylight Alpha Background + clouds ( update 20.06)

[visuall]

final + post prod phtoshop

added fog for raylight effect

just added fog for raylight effet

I do not know if this is a good solution, but it's the only one I have found to overcome the lack of management background on octane without the need to render two images (hdri + sun)

Good thinking there Visual!! The lack of HDRI + sun in Octane is a great limitation for me and many have been asking for it for a long time. So my guess is that the Otoy boys and girls have it HIGH UP on their AGENDA (ahem).

I'd love to know if you come up with a clever way to include clouds in the deal.

Your work is inspiring.

thank you seeker,
uses the same technique, a plan with an alpha texture cloud;)

Hi there

not sure what you're doing here - is it an hdri mapped on to some geometry with an emitter added?

Hi,
No, si a plane with alpha matérial for cloud and background , sun/sky emiter only

I go with a fully 3D approach on this kind of scenes.
So some bushes and trees in the background and a simple image in post to replace the alpha.
Most of my scenes are made this way. It is fast, renders are not throttled down because of alphamap rendering and I can replace quickly if needed.

If I have an open scene where I need reflections I scatter more 3D and maybe some building around the scene and get a nice bounce of light.

But what i definitly would like is to use a HDRI as a reflection slot. Like Maxwell Render uses it.

Great! Thanks Visuall. I'll play with that a bit.

Mbetke,
I don't get it. You're not bringing an alpha image INTO Octane - I get that. But don't get how you place a 'simple image in post to replace the alpha'. Perhaps I'm missing something regarding Octane's output ability but, depending on the image complexity of course, inserting a background image in post can be extremely tedious (unless you have the simplest of large openings in a space). And so I think Enrico's approach to render twice (one with HDRI and one with sun) and simply merge in post is a much simpler and less time consuming approach. And Visuall's approach seems a good alternative to avoid that. What are you doing that is different to a normal post process?

In your shot your trees are 2D planes with an alpha. Also The cloud.
I use real geometry there and no clouds.
All I meant is I render my image with "alphachannel" and put an image behind the scene. Sometimes some 2D trees too.
In your case I would just place the ground with the slide (maybe a line of bushes) and all behind it would be black on my output.

Like this image:

Behind the tree and white fences is just a landscape image.

Its the most easiest way to have a small scene which renders quickly and pasting a background image doesnt even take a minute.
If you put your background into the rendering you have to setup your 2D trees, the cloud image or even re-render if client wants suddenl pine trees and no apple trees (just as an example).

Ah,
So you just render with black background to make it easier to replace in post. Thanks for sharing Mbetke.

PS: that's not my image - at this point I can only aspire to the standard of work that Mr Visuall produces. But I'll get there eventually.
