I am currently working on it, but I am not sure if I'll be able to do an HDR version as the program that is commonly used is like 200$...

By now I can tell you I've improved the quality of the sky and made different layers of stars so there is a feeling of depth. I'm also testing some dynamic colour changes with proxies (for stars).

It should be up in a day or two.

Thanks for your feedback ^_-

What do you mean by 200$? All you need is to convert skybox texture to 16Bits/channel mode, and also this

First version of HDR Shop was free, now it is not. I bet there are other ways to do it, but I haven't looked much into it as it wasn't in my priority list.

I'll finish what I'm up with and later I'll investigate this and convert the 2Dskybox to HDR if I have enough free time.

Thanks!

Well, Photoshop have ability to convert textures to 16Bit.
