How to render a 3d object in a texture So I have somewhat of a 3d space inside this texture and I wanted to know if it is possible to draw a 3d sphere inside of

how do I tackle this with nodes if possible at all, should I use a Parametric Sphere Formula?



the end goal a sphere inside a sphere
This isn't perfect as the shading is a bit off. But maybe you can improve on this:

(If you add a vector mapping node to the object texture coordinates you can scale the inner sphere.)


All that is necessary is the dot product into the bump node, but this causes the auto smooth shading to go away. So the color ramp is trying to add smoothing back, but not quite perfectly.
