Here i have a very fast and small atmospheric scattering effect which works in 2d uv space (obviously good for 2d game backgrounds). Its without any media, very customizable and very small in size.
I am thinking of putting it up to assetstore, what would you think the price range should be?

This is always a fundamental question, isn’t it? I would propose to consider the effort (man days) firstly, and maybe a small discount you would feel good with. Later on, you could include more features and increase the price range accordingly.
Are there also night cycles available ? Stars, Moon, Milkyway and so on…
Currently it doesnt use any textures but just maths in a shader.
But I can add those extra features as a layer system such as clouds, stars, moon…etc (You can also add it yourself though)
Right now, its just a 2D and much faster version of my Atmospheric Scattering effect for Planetary Terrain.
ah ok. Thought maybe stars or similar things could be procedural. But i think it can be placed manually as a bitmap, right ?
Often times, its much faster to use textures rather than expensive maths.
I am submitting the package to the assetstore today with the price of 5$ (as compiled shader)
Those who want the source, you can buy directly from me (price is negotiable)
