Hey guys! This is a funny one!

I’m trying to type uv in the input, but the v is not getting there! Then I tried to write a v in the comments and it is working. After that I try to type v again in the Name input. Not working. After a few g-s it accepts the v. What the hell? 
CTRL+V lock maybe?
Thank you!

uv might be on the reserve name list but let me check.
Yep “uv” on the reserved name list. What does that mean you ask? There a list of names what we do not allow you to name your nodes because they are reserved words. Other words include “normal” “position”. The full list can be found inside nodeMaterialBlock.ts inside the validateBlockName function.
Now what is interesting to me, is there used to be a pop up that would display if you tried to use one of these reserved names, instead of just cancelling the input. Not sure if this got changed in recent months?
Hello @msDestiny14!
Thanks for clarifying!
Just as a status update I fixed the line that should make the pop appear again so there wont be any confusion.
