Using shaders on the dome

Gee I hope I describe this right I want to use a star field shader to the dome for a night time scene and still use the light preset I'm using. Is there away to apply a shader to the dome?

Thanks!

    No. The "dome" is an HDRI, (at least for Iray). There are several night / starfield HDRIs available.

    Render it with the dome not being rendered, so it is a transparent ALPHA-MASK in the final image.

    Now, just insert your own starfield image as the background with any external program.

    That will retain the light from the HDRI dome. Honestly, if they are stars, you don't want to attempt to place them in a 3D scene, they are too distant and essentially just a static image/vision. However, it you wanted to also simulate "horizon fog", I could understand the importance of needing them in the rendering, as an image.

    Plus, Daz will try to compress your sky/star image, and destroy the high-detailed stars, when it "renders them". (The advanced settings for medium-threshold and high-threshold.)
