Sun colour OXP

I would like to have or make an oxp that simply alters the sun colours. Now all stars are white.

I want to see some red giants or blue hot stars.

Having not yet upgraded to 1.72 I'm confused - do you mean all background stars are now white or that all system stars are now white? or both?

Irrespective of that an OXP which alters the size, colour of a star within acceptable scientific/astronomical parameters for the habitable zone of orbitting main planet certainly gets my vote...

I mean the sun not the background stars. There is a startexture.png or something like that in the main texture dir but it doesn't alter the star colour

Oh - ok - I'll miss my colours-by-dulux type stars (bluey-white, reddish-white, greenish-white etc...)

Every star has a deferent corona color that illuminates that to the rest of the system. Is some cases that color is blue in others white etch (a very big verity)

I am not so sure about the size but I think that not all suns have the same

Also i am not so sure that this texture has anything to do with suns

Please let's not confuse things too much.

'Star' in Oolite refers to the background stars. Therefore also the startexture.png has nothing to do at all with the sun, it's the texture for the background stars!

The big white thing in each system is a 'sun'. In 1.72 it just has become its own type of entity--sun entity as opposed to a subform of planet entity, as it was before.

And Ark is right. Suns are not all just white. There are reddish, greenish and blueish variants. But the colour difference is subtle, and has mainly to do with the light the sun emits. So it is visible mainly in the overall impression you get from a system. Some systems look reddish, some others greenish or blueish. And this has always been so (at least since 1.65).

Does that come in corn flower blue?

The actual surface of each sun is in fact coloured.

is it possible to make the color difference less subtle? I see the subtle differences too but it can be a bit more dramatic.

Probably add a color-property to the sun object class?

Here's a screenshot from Galactic Civ II Twilight of Arnor. If Suns in Oolite could look something like this AND in different colours I would be very happy. Even with a low-res texture or something

So a sort of Sun-Redux.oxp.

BTW Galciv II is Excellent now. Tip!

I'd definatley second that! I don't know how do-able it is to allow a sun texture to be added, but even a very simple set of 10 or so (mixed with different colours) would give a huge varitey. The Corona of the sun looks great on 1.72, but the sun itself is just a plain sphere.

This is how it COULD look. Photoshopped it.

Urgh. You people have no taste. :-)

(There’s also a technical issue: the sun really is drawn as a disc, in order to simplify rendering. Texturing would require a sphere, which would increase load on low-end systems.)

An ugly disc. But is it technically possible for higer end systems to do a 3D sun or via an OXP Ahruman?
