I’m just experimenting with the new Atmosphere addon announced for Babylon.js 9.0.0. I’ve been trying, unsuccessfully so far, to get a visible sun disc and/or greater sun glow and longer duration (higher sun altitude) sunrise/sunset effect similar to what is possible with SkyMaterial.
OK bumping up atmosphere.physicalProperties.peakMieScattering solves the greater sun glow and sunsets/sunrises, but I’m still missing a nice defined sun disc. Of course I can make and position a sphere for the sun disc, but it’d be handy I think to have it as an option in the addon i.e. showSunDisc and sunDiscSize etc.
Actually now that I’ve gotten used to it, I think Atmosphere is better off without a sun disc. This way the content author can implement it the way they like.
