Hi!
How can I make bright little stars?
My stars are always greyish, and when I increase Luminosity they get bigger and bigger, but I want them to stay small.

What a strange combination of nodes. At first I doubted if any dots would appear as both color adjust shaders are set to black-black, but it did show some pinpricks. Strange.
Here's a background file that's on the forum somewhere as well. I think Dandel0 made it (not sure). That works well as a base, and I don't think the stars are too big. The principle is quite simple actually, kind of the same the file you used.
Thank you for the quick reply and the example file.
Unfortunately, even here the stars are grey and not bright-white.

odd...that .tgc has always worked well for me....
Had a look at the TGD. I think it's going pear-shaped with the merge and subsequent colour adjust. To simplify it you could use an Add scalar (or Add colour, I just like to be minimalistic) to replace Merge Shader 02. And don't forget that antialiasing might be smoothing your really small stars

This is actually a really useful feature for creating binary masks at a specific value.
Can you explain what you just wrote, Ben? How does that work... I mean black is kind of black, isn't it? Though I noticed that with clamping, reversing and such, black is not black at all.... confusing sometimes.
Thank you :)
Now I got bright stars ...

Short answer: Matt told me.
But it does make sense. Numbers between the black and white values are interpolated between 0 and 1, numbers beyond beyond the black and white values are extrapolated (or clamped). If they're both identical, it still holds true that larger values will be white and smaller values will be black.
Still hard to comprehend, but I'll keep that in mind. Might be useful knowledge some day.
