Texture Problem on Multi-prim object

I created an object with several different sized spheres. Some of them have different textures I uploaded from Photoshop. My problem is that in viewing the object from different angles, parts where different prims intersect become transparent or ojects seem to disappear. How do I get rid of this effect and make it look like a more solid object?

Sounds like alpha sorting to me. Can't be overcome, unfortunately. You can't have textures with alpha channels overlaps each other. See the sticky on alpha channels, etc. at the top of this forum.

You will need to re-save your textures as 24-bit tga format, and import them back into SL. Some of the textures (possibly all) have been saved as 32-bit TGA, which acts as a transparent texture (and is affected by the alpha sort glitch) even if there are no visibly transparent places there. For example, there were a few marble and granite textures in the Library section of inventory that look solid, but are 32-bit and suffer the alpha glitch.
