alpha sphere around an object causing problems?

I’m making a model earth, and when I put a sphere around the world for the atmosphere and make it’s alpha .25, and i render the world doesnt have it’s texture, it’s just a grey sphere.

You may need to either:
a. make the material on the world sphere recieve tranparent shadows (Shading->MaterialButtons->Shaders->TraShadow)
b. make it so the atomosphere does not give shadows (Shading->MaterialButtons->LinksAndPipeline->Traceable AND shadbuf)

Oh! and make sure you select ZTransp as well. (for the atomosphere)

that worked, thanks!
