Starlight for walkthrough

It should be fairly easy to do

here I've just used an image of some stars as a texture on the ceiling and then have made the texture self illuminating

If you want to make it more interesting, I would try transparent illuminated png files which would allow different colors, depth and/or light intensity.

transparent illuminated png files

Pretty sure you cant do transparency and self illumination

Sure you can.

Whoops. Thanks for the correction.

Now if we could just get partial transparency to not be grainy we could actually use this for something useful.

you mean like stars... That have no detail anyway... For a ceiling perhaps? Also, the source picture (me) is low quality and the emissive material is purposelessly blown out to make the point but obviously it works fine when setup up properly just like when using it for phones or TV screens etc... so I don't really get the complaint. It seems a perfectly valid workflow and option.

My complaint is related to partial transparency in general but specific to self illuminated partial transparency we have... fire, backlit transparent film, creative gobo lighting effects, caustic workarounds. etc.... the current implementation works acceptably well for on/off areas of opacity only. I brought it up because the OP request would most likely benefit from the type of subtly that this bug does not currently allow for.
