Black Hole project revisited

I actually don't know if the movement of a pop area will make instances locate at different locations (not relative to that movement I mean). I once noticed that a small movement just shifted them, and that would then work.

Unfortunately I don't know enough facts about relativistic effects around a blackhole.
I was impressed that the behavior of the "frozen" objects like the astronaut look correct. I could only imagine, that usualy from the perspective of the beholder we should be overtaken by debris... but they would slow down - or stuck in time too... theoretically...

Weird physics!

But just as interesting and nice looking effect without physical correctness you could let some debris rotate with the forground part of the accretion disk and some debris let overtake us... ? Just an idea... :o :)
Hi DocCharly65 (can i call you only Doc?) ;D

In the scale of the scene, the black hole have only 100 km of diameter, so is not so bigger. but if we traduce this to real scales, just the fact that you can see almost all the accretion disc, it means that this "little" black hole is so far from you, as we are from Mars. So yeah, we dont need to worry about the relativistic effects at this distances. a planetoid is also visible in the animation moving fast near the accretion disc, so, that should give you an idea about how far we are of the black hole. ;)
Hmmm, what version of Terragen does God use?

Real scale rendering is in fact not easy ... I tried it some years ago and almost killed the whole scene (usually Terragen also crashed after some frames rendering) when I tried to render a 1:1 earth with an Enterprise in a correct orbit with the correct speed... all values about some thousand kms and kms/h -- that was really too much for Terragen (3.3 as I remember) Not any GI interpolation and nothing else helped against flickering and the camera path began to be a chaotic fractal itself when I tried to change to slow or stopping scenes...  ;D ;D ;D

by the time we get older, more patient and a little bit more experienced ;)

Not the first time I read the short form "Doc" -- that's ok :)

I liked that line ;) 
About the rest, i not tried animations at real scale/velocities yet, but for eg, another users like Hannes haved some successful in this...

The debris looks better now, and it seems that everything is ready for another (final?) animation, BUT, before that, one last still image...

Looks really nice. I have to say the HDRish tones on my main Samsung HD monitor dont look to good. They cause colour burning on the monitor (tones become flat and disconnected from gradient flows) but on my phone which is HDR they look amazing. My GPU isn't even outputting HDR on my PC so confused why it looks off.

That's because this last image and animation, are not HDR enhanced :P
Check my 2nd older image and animation...

Your HDR marked images aren't HDR? I thought I could read. I wasn't referring to the last image, I was specifically talking about the HDR ones and their effects across my monitors.

Latest image is nice but lackluster imo without HDR (maybe needs more colour variation). But HDR on my non-HDR monitor is a mess of burned colours and not cross compatible is what I'm saying (like other HDR images seem to be)

Oh okey. relax, you definitely can read, is just that i thought that you was referring to that last images. sorry.
i have just one HDR TV monitor, but i not always test all my images in my TV. i gonna do it again for the final animation for sure.

I was being more sarcastic lol

I'm curious though how HDR images are done when it comes to non HDR displays. Not very familiar with it. I

Trust me, when analize in PS, you can notice the difference...
