Have a look.
With light sulfury clouds.

Now without.

You can choose to use the cloud texture or not and the same with the nightside lightmap. I will let everyone choose how they want to use it. I wasn't originaly going to release this as a seperate texture but Darkmiss kind of talked me into it. The package contains a combo of .png and .jpg format. The file is about 13.5megs and the textures resolution is at 4096x2048. If you feel the need to ajust its size for you needs be my guest. There will probably be an update to this texture but I am not sure if I will release it seperately from the rest of the HD 28185 system package when its done. Time and nagging will tell. Download it here. http://ennui.celestiaproject.net/~impulse/Volcanic%20Moon.zip
Have fun with it. Now I have to get back to work on the rest of the system.
