Hi 凯 胡 CCash_Hoo ,
We had the same question before, but I cannot find it anymore and I also don't remember what was causing this (although I know, it was something really simple).
If you don't mind uploading your .blend file, we can have a look and see that we get this fixed.
(And yes, the Image button is missing in the first post, directly under a Lesson...it's a known bug at the moment...)
Without seeing more of the shader I can't give an exact answer.
But I'm guessing, looking at your neat network of noodles, there is one that stands out to me and probably the culprit.
If that noodle is plugged into the output node, then all you are seeing is the random color plugged into the HSV node through the output.
Hi,Martin Bergwerf
Thank you very much for your answer. Can I send my .blend file to your email?
Hii CCash_Hoo ,
Having a look at your .blend would be better; I, for one, cannot read the Nodes and I have a suspicion, that the mistake is not in the Node tree itself...
Oh, it seems so. Since the gradient repair class was a bit difficult, I skipped it directly.
Man this makes me want to make my Cubicity city, I think those buildings with all those colors look cool. I can imagine a rainbow Cubicity City. Skittles advertisements all over, Unicorns and an actual rainbow in the sky. Dangs I wish I had more time in the day. In my Cubicity City, a day will last 72 hours.
