Starfield

How do you make a starfield in xsi 2.0.1?

This shader renders starfields and it's very fast.

thanks! I made a sphere and the starfield shader, but I see these rays/lines emit from the sphere. What's this about?

The Legacy shaders don't work well with other objects in the scene. Just render the starfield alone, then composite it in with the rest of your scene.

Ed,

think you could give a step-by-step instruct for us newbies on how to composite a sphere and the legacy night shader?

[richard-sher]

Render your starfield animation alone. (Objects hidden)
Render your objects with the starfield turned off.
Load both image sequences into the FXtree.
Use an over node to connect them together.
Use an ouput node to save the results.

Or skip all of that and apply the legacynight shader to a sphere that surrounds the entire scene. (It's slower, but you won't have any artifacts.)
