In my clouds textures of Venus,it appears pixelated and not somewhat transparent,this is,when I turn clouds on in Venus,it appears bleached,spotted.In the case of Uranus,a very artificial appearance with big pink strips and a pixelated appearance,too.Look to my ssc and see what could be wrong :

Daniel,

your ssc code looks reasonable.

I'd guess either there are problems in the image files themselves or in the OpenGL drivers for your graphics card.

How big are the cloud and ring texture image files?
What do they look like when you load them into a paint program?

What graphics card do you have and what is the version number of its drivers?

My cloud textures are all from John?s site and this one is 2048X1024(the same buffer of my video card).The appearance,in a paint program is absollutely normal.My video card is A NVIDIA Geforce 4 MX 440 SE 64 MB and my driver is Nvidia 43.45

Well,in fact,I see more or less the same in my Paint program,but the same texture was more accurate,and in Celestia,this pixels become more exagerated.
