Thanks John. I am using the ssc file that comes with the clouds addon. The problem is that the base texture of Jupiter already has a red spot on it. The solarsys.ssc file names that texture. When the semi-transparent cloud addon is added in the extras folder, it does not modify the base texture to remove it. Rather, it overlays the base texture with the 10 layer cloud texture, so there are actually two red spots visible ... one on the base texture and one on the cloud addon. here is a screenshot (notice the 2nd red spot under and just to the left of the cloud red spot. As the planet rotates, the cloud red spot moves past the base red spot, and both becomes visible.
What the cloud addon needs to do is first modify Jupiter to remove its base texture, as the 1st line.
(Modify "Sol/Jupiter"
{
Texture "empty.*"Or ... the speed and position of the red spot on the cloud texture needs to be adjusted to permanently overlay the base red spot. Am I still missing something?. Help!
