Problem summary
When adding a material override and attempt to change a color parameter if it was not initially set as a local variable or was disable from a local variable, any attempts to change its color won't cause any update to the color parameter unless it is set to local in which case changing the color will update as normal
Customer reported version
Katana 6.0v1
Customer reported platform
Ubuntu
Steps to reproduce
In a new scene, create a Material node in the Node Graph
Create another Material node and connect it to the output of the first Material node
Set the first material node using any shader for example a dlsurfaceShader dlPrincipled
Change the action of the second Material node to "override materials"
Set the override path as the first Material node and drag a color attribute from Attributes tab in Katana from first material node to the second Material node under attrs
Disable the local variable on the color parameter and then change its color
Expected behaviour
For the local variable to update once the color of the material changes
Actual behaviour
The material doesn't update when changing colors
Workaround
Enable local variable and proceed to change colors
