About Lunarcell,.. I don't know if this quick sample of saving 'layers' is what you mean by 'saving textures' but here goes..
Step 1: Create a planet in Lunarcell
Step 2: Launch Lunarcell again and without changing any settings click on the export PS layers button.
Step 3: Load the .psp image that lunarcell just created to see the results.
Cheers!
