Quote - I'd like to see some pics of yours that show "perturbation" value changes done to lumber

 

like i said, lumber mill is end of the tree, can't have outside values control it, one of the ones i wasnt able to rewrite, hmm wonder if daz will share source code :)

brick is an example that i could do, but leaving for work in 5 minutes, no time to write a formula so i'll try explain quick. brick you can choose many variables, but they can't be controlled by any shader inputs, say i want a circle patio design? that requires the "width" of the brick and mortar to go from wide at one point, to narrow, before you can warp it to a circular pattern, in poser i could simply have V coords effect it, thus adding more bricks to the row as V coords go from 0 to 1

in carrara i'll admit this isnt impossible to do with workarounds, i could make 1 branch for every row of brick, but that can lead to hundreds of branches, so my solution was to rewrite a new brick plugin to use, that allowed its variables to be changed by outputs of whatever i choose

late for work, hope that helps, gotta run -.-
