Here is the background stars project for you to use in your project. Comes with a switcher group for enviro light and background object (for daytime, though you could also just animate/increase horizon fade. Default camera, and a exposed camera to compliment the exposed enviro light.

Project is setup for speed in mind, so some fidelity over previous versions may be lost.

Thanks for sharing this, WAS. But why is google requesting access permission? Isn't there a simpler way to share?

Btw. I found out why you may have had faster renders than I had initially; depends on the size of the stars. Yesterday I enlarged them to 50.000k (from 100m), and rendertime dropped dramatically.

Hmm I guess that may sorta make sense. The sampler maybe spending more time trying to figure out what's a star?

I have been using Google request system because I had found some of my work on Warez-BB being shipped with illegal Terragen, and was not happy. My cement shaders and other specifically "licensed" stuff with no license. So figured I'd use the request feature for shares moving forward. I can see who wants download files. I often get 10+ requests a day on various files here I moved to requests. With this I have a paper trail like receipts of I need to contact anyone. I was going to setup a website and shopping system but figured all the fields would be even worse.

As a note, one thing I know probably won't translate well to any sort of animation is probably the galaxy noise multiplication. I made it fairly big hoping it would, but my hopes aren't high. I suppose I could test... Not sure why I don't.

Dune

I understand, and it seems a wise decision to do so. I wonder how many requests you'll get.... nice way to test the involvement with TG of (unknown) visitors.

Animating certainly has it's problem as Dorian and I found out; stars flickering like fireworks. So eventually a separately rendered still background will be comped in the animation.

Seems 18 people so far. I recognized few emails as members, and a couple seemed like spam so didn't send it. Can't imagine numbers and random letters is a valid persons working email. I wouldn't be able to remember that. 

You're probably right, and that is probably a far better method to get it in a animation.

Dune

There should be a way to distinguish spam from real, but not this way, I guess. Like people having to write something real.
18 is quite much, given the dead silence here. Too bad these people just grab and never show and contribute.

WAS

Probably a spam database I can refer to. See if the email has been reported for spam/phishing or anything.

And yeah I have thought that a lot. I routinely get requests from a lot of people new people. Still curious how mine renders. The dimensions are quite large on stuff so most stars are actual circles (at proper resolution)

WAS

So I did a animation at 1/4 Sampling level, and 0.005 pixel threshold, with AA on Cubic B-Spline, which I read is good for particles that "stutter". It honestly doesn't look half bad, but is much to fast to really tell much, and the motion blur was left on. So doing another 30 frame render instead of 10.  May need to up the resolution though, we'll see if 720p isn't working.

The mp4 is from ffmpeg and will likely only play on VLC/MPC or if you have K-Lite video codec pack installed for native windows. Slowing it down as far as I can go I notice a few streeks coming in and out but they seem to be following correct path, and the brighter stars seem to be holding position.

Dune

Had a drink too much when operating that cam? :P

WAS

Spin, twirl, and zoom. Stars look pretty much fine at 720p. :) Minimal twinkle, and only coming from the small fainter stars so looks natural imo. They would be twinkling. Galaxy noise should probably be disabled or enlarged for animation. Doesn't look the best.

I do believe Cubic B-Spline really healps. Doing reading last night, the edge correction of default, or even sharp AA, will cause shape deformation and hard edges to create a lot of change in light. Cubic B-Spline softens the edges and helps mask that effect.

Dune

Yes, this convinces me! The problem with the (my) stars Dorian used, was probably because some noise had 4D noise checked.

Indeed, I do think we would probably be best compositing the sky still though. Higher MPD and AA settings will only help, and I imagine Cubic B-Spline on terrain may be a little too muddled, especially vegetation.

Request waits

Sorry if it takes me a few hours to get to your requests. I'll have to note this in the future. It seems in an effort to get you to use Google One (or some other account subscription) google is no longer sending request emails live, but all at once at 5:00AM, when I'm asleep for another hour or two. It took me a couple days to catch on to why I wasn't getting barraged with tons of emails at once waking up. Ironically after cancelling Google One before Christmas.

Great results here! I am quite convinced by the animation tests, this looks really clean. How many AA were this rendered at? And how fast was it?
