Acid Rain, please do not post the same (or close enough to be practically the same, as it is in this case) as is written in Section III of the forum rules.
You can edit posts you made with the pencil icon in the far upper right of the post.
Also, please post suggestions here.

I think so ;)

Acid Rain,there are plans to improve everything.  Star Citizen has an entire team of people working on it and has raised nearly $150,000,000, SpaceEngine has a programming team of 1 and has raised a little over $52,000.   SE will implement most of that stuff, but probably not soon.

Out of curiosity: I'm translating SE for the Dutch, but I have yet to see any sign of any translation group anywhere. Will this eventually happen again? I've seen this being asked before, but it's been a while and since progress on the game continues, I'm guessing there's translating to do as well.

So uh, could I just get some more of those sexy nebulae pics to drool over?

Duke's nebula update. Still a lot of work, integration into engine, correct blending with stars...

Something looks like spiral galaxy (or protoplanetary disk?):

That is the feature I'm mostly looking forward to in next release!

Work progress - 0.9.8.1

Recently I have working on a proper HDR with autoexposure, and adding a new shiny bloom effect. In process, improved quality of MSAA, and many other things. Now, finally, SE is able to display very large difference of brightmess, and true relative brightness of objects.

Earth and Moon. Relative brightness must be adjusted for all Solar system bodies. More precisely, scripts will have a physical-based parameters for textures calibration. Something like MinPixelBright and MaxPixelBright in some physical units like luxes.

scr00323.jpg


Saturn and Titan. No stars visible!

scr00325.jpg


Pluto and Charon. Stars are visible (although their brightness is still not calibrated, so this may be wrong).

scr00324.jpg


Saturn and Mimas with shiny glow.

scr00296.jpg


scr00295.jpg


Earth's night side. Atmosphere is glowing not in red color, as expected... I have to tweak the atmospheric scattering code. There is a tail of the comet Encke visible in top left (comets brightness is not calibrated yet).

scr00329.jpg


ISS over night side of the Earth. Starry sky, city lights, aurora, clouds and ISS are illuminated with a moonshine. I can use real photos from ISS to calibrate such scene.

scr00297.jpg


When ISS enters sunlight, it looks almost like explosion, until virtual "eye" adapts to a high brightness.

scr00298.jpg


Ship's light in the "night". Looks too shiny? Radiator's glow is too bright and too hot, it must be separated in its own texture, controlled by the graphics engine.

scr00330.jpg


Engine exhaust looks extremely bright, because its brightness is calibrated for the the next picture.

scr00331.jpg


In the "day", engine exhaust is barely visible. This is why its brighness was so extreme. Radiators glow and lights are completely invisible.

scr00332.jpg


Molten planets looks interesting in the Solar system browser.

scr00327.jpg


Glowing lava now looks really "glowing" (that is a planet in the sky, but it is so bright compared to the night moon's surface, so it is being overexposed).

scr00328.jpg


"Interstellar-style" black hole looks much better with a new bloom.

scr00294.jpg


With HDR, it is now easy to explore extremely bright object such as stars and accretion disks. Autoexposure speed is a bit too slow in this case (and adaptation back to starry sky), I have to derive a better formula.

Wow! Just when I thought this update couldn't get any better... The wait is killing me! At least it'll be worth it :D

The graphical improvements in the next version are amazing, especially those nebulae - the second picture looks like something straight from Hubble.

(Sorry for the double post)

Also, do stars inside the nebula illuminate it?

SpaceEngineer, these nebulae look really great but will they have textures in the future, so we can have real nebulae? these are probably diffuse nebulae, did you already do any planetary?
What do nebulae look like with this new hdr and bloom?

No, and it is very complex question, how to integrate stars into nebula. You have to convert them to a sdf somehow (signed distance function).

This is very complex too. First, how will you generate a 3-dimensional shape using only a photo? Second, how will you convert it to sdf?
