Distance Shader.
The “preview text” (the red background) is upside down in the preview window (Distance: no objects) and does not change either once an object is assigned to.
Then there are some IR refresh issues.
Load the scene and run viewport IR. Select Circle.1 and move it along X. No change in the viewport. Disable the Spline Mask. The result in the viewport goes red (which is ok).
Turn the Spline Mask back on, the viewport stays red (which is not ok).
Restart the IR, all is back to normal.
Hmm, I am using the Version: 7.0 daily Jan 22 2021 right here.
Gave it another shot though and I think I wasn’t quite clear enough what I +1 oned. I wanted to let you all know that the IR still doesn’t update on changing the “Circle.1” object which means that the distance shader doesn’t quite update reliably when running it with the IR.
I did mess around with other scenes and it tends to work fine although sometimes you do need to restart the IR for the distance shader to start working.
Still no refresh with the latest V7 daily.
If you switch off the spline mask and switch it back on again, you get a “blank” plane with no refreshing splines either.
