I have wanted to try this for a while and since I had some down time I finally got around to giving it a whirl.

Obviously a LOOOOONG way to go but the basic concept works and is not too hard to achieve. It should be possible to go through the portals.

Now to work out a more interesting (and longer) camera move and some better moodier environments.

Ooh.. Can you get the bloom/starburst from the setting sun to flash over the foreground world by rendering the sunset world as an EXR and rendering the foreground world with bloom/starburst?
Just because milk is white doesn't mean that clouds are made of milk.

Quite possibly. Experiments continue ...
It would be great to have the post effects as a seperate render element (hint!)
I was wondering about doing a seperate pass with a very thisk atmosphere that could catch some rays eminating from the portal and then multiply that over ... we shall see :)

Really amazing! Looking forward to your next step.

DocCharly65

That's very impressive and looks amazing!

Dune

That's very cool! I think I probably know how you did that. Very intriguing scene, I like that sort of experiments!

j meyer

Yeah, cool stuff. Curious to see where you'll take this.

For some reason I can't watch this. Vimeo just shows a image? Or is this a image?

It should be working, it's a 200 frame low res video.
Try a different browser maybe.

Got it.

Is that done just in Terragen?

That's really cool, love the boundary effect. Some bloom might look cool on it.

A few times now, someone has asked about using bloom and burst as a separate render pass.

These are Blenders's compositor passes using filter streaks and simple star, tolerance 0.01 and 0.5 respectively. mix 0.5

Blender picks up the light in tolerance setting to make the streak or star. I could not get a bright sunburst ray like TG does.

I'm thoroughly confused. 😂🤣

@luvsmuzik
Thank you, that's a cool trick to know. I composited the three scenes in Nuke and I'm sure there is a comparable filter in there.
I would probably just use it on the boundary effect.

@WAS 
Yes this is confusing the hell out of me!
Right now I need to make up about 10 scenes that al work with the same camera path, then decide which will be main scenes that the camera goes "through" and which will just be side shows that the camera just passes by.
It's an immense headache and I expect progress to be s l o w ... .. .

Oh I get how it's working now. That makes sense and pretty clever, if not laborious.
