ok mr shonner :) i want lumber shader to have the "perturbation" value change from the output of a color gradient controlled by Z coords, see? can't be done, lumber mill shader is at the end of the branch, same for tile, brick, etc. in poser i could use brick controlled by 100 math nodes (which thankfully carrara has formulas yay) to control design of the bricks, but carrara has brick at end of the branch, as another example.

i recreated many of them to allow me this control back, but i have limits :(
