Problem Sun

[vinny2000000]

Hi, guys! I think I found a bug: when I am flying to the sun to do a fly-by with the sun the sun never got any bigger. The sun as seen in this photo is about 1,000,000 kilometers away, the sun at the distance of about 1,000,000 kilometers away in orbiter 2024 look the same at about 1 AU or about 150,000,000 kilometers away. Thanks!

Cheers,
Vincent

IIRC the sun is not a real body in the game, just a texture at the center of the game world

That is disappointing. I would prefer spaceflight simulators that is realistic as possible like the sun is a real body.

Get on the repository and start working. Please include a proper MHD simulation so we have nice CMEs when you are done.

Yeah. Sun should be sphere like planets, not billboard. There is procedural star rendering. Google it.

If realism is your goal, there really is no better option than Orbiter..

Thats at least a good option for Orbiter for permitting generic star systems - of course for the sun, I would prefer setting more parameters to reproduce our star as we know it. Maybe there can be a good solution for all main sequence stars.

surely there must be a mod for the sun??

You can just swap the texture. A physics representation of the sun or a 3D visual of the sun is not yet possible, but since Orbiter is open-source now, it could be a valid feature for the future. And yes, modding support is important, I would even suggest taking the chance and permit proper multi-star system support... but developing the idea and requirements (or user stories) even just HOW this should be done will take time and discussions to get to a solution that either pleases everyone or that everybody hates equally.
