ramp_rgb Katana

Hi There

it seems that the node ramp_rgb attributes changed in the latest KtoA versions

before we could access the ramp thru position and color

node = NodegraphAPI.GetNode('ramp_ rgb')

positions = node.getParameter('parameters. position.value')

colors = node.getParameter('parameters. color.value')


now its ramp_Knots and ramp_Colors

node = NodegraphAPI.GetNode('ramp_ rgb')

positions = node.getParameter('parameters.ramp_Knots.value')

colors = node.getParameter('parameters.ramp_Colors.value')


Could you confirm that not an issue and that was the intention

Thx in advance

We got this issue too

Message 3 of 4

This is not an issue and was changed in KtoA 3.2.0.0

due to multiple ramp node not being able to be exposed in NetworkMaterial without this change
