Does anyone have good textures suited towards red giant and supergiant stars, especially detailed ones (which include convection bubbles, etc.)? Thanks.

I made a texture for every spectral type including M stars. I mostly had main sequence stars in mind but depending on what you're after maybe you might find my texture usefull:

You can download a 3D overlay for Betelgeuse here (addon package 8). I'm not sure how accurate it is.

There isn't a download link for the Betelgeuse addon. It just straight up opens Celestia.

That addon, however, is based on outdated measurements of Betelgeuse's size (905 million km as opposed to 1 billion km), so the convection bubbles do not completely cover the star's surface.

Celestia 1.6.1-ED uses deep red giant textures for Mira, Rasalgethi, Betelgeuse, Mu Cephei, and VY Canis Majoris. There is also an addon on the motherlode that turns Gliese 581 g into Krypton, the home planet of Superman, as well as giving the star a red color.

Maybe have you tried this link which instantly downloads the addon that includes Betelgeuse that SevenSpheres was talking about?
