Should I report this as a bug? Or Am I missing something?

Hi,

I made this very very simple graph :

4485175--412963--Graph.PNG
4485175--412963--Graph.PNG1085×657 25.4 KB

Everything looks fine, but if you actually pick the colors of the 3 grey square, you don’t get 0.5 grey as you should, in fact, you dont even get the same values???

  • You get 0.73 grey (188, 188, 188) on the right box, I don’t know why it’s not 0.5, but if picked with an hdr color picker, it does show (128, 128, 128) but is nowhere near a true 0.5 grey color… Why?
  • Second, the bottom box shows (200, 200, 200) in non-hdr, and (138, 138, 138) in hdr, how does this make any sense?

I’m going crazy trying to understand what’s wrong with some more complexe graph, but I can’t even understand this, please help :frowning:

Okay the values not being the same seems to be a bug in the 5.2.3 version only (i’m using 2019.2.0a13) but in the lastest shadergraph version, in 2019.1, it’s fixed.

I still have no idea why 0.5 as a color does not translate to exact 0.5 RGB values though.

Not at all related to your issue, but just a reaction to the screenshot. What’s the story with the top inputs into the multiply nodes? You’ve connected another node to those inputs, but it’s still showing the input fields to manually enter a value? Is this some 2019.1 bug? Is does it mean something special for those both to be shown together?
