Okay, this code works:

import c4d

def main():

    neon = op.GetObject()
    UD = neon.GetUserDataContainer()

    g_dirty_glass_presets = neon[c4d.ID_USERDATA,185]
    g_smudges = neon[c4d.ID_USERDATA,183]
    g_dirt = neon[c4d.ID_USERDATA,192]
    g_scratches = neon[c4d.ID_USERDATA,189]
    g_scale = neon[c4d.ID_USERDATA,193]

    g_ext = neon[c4d.ID_USERDATA,25]

    reset = neon[c4d.ID_USERDATA,229]

    if neon[c4d.ID_USERDATA,185] == 0:
        neon[c4d.ID_USERDATA,189] = 5

I have set neon[c4d.ID_USERDATA,189] to a float. How would I set it to a gradient? How would I set it to a 2D vector? Thanks.

This is from another scene I made. It resets User Data by inserting values when a button is clicked on. The button then resets. This code works. Why is the other code I posted not working?

Hi, I am trying to use values from a preset to update/change a User Data field. The console prints out the correct value but the User Data field remains unchanged. Can you tell me what I am missing? Thanks.

import c4d

def main():

    neon = op.GetObject()
    UD = neon.GetUserDataContainer()

    g_dirty_glass_presets = neon[c4d.ID_USERDATA,185]
    g_smudges = neon[c4d.ID_USERDATA,183]
    g_dirt = neon[c4d.ID_USERDATA,192]
    g_scratches = neon[c4d.ID_USERDATA,189]
    g_scale = neon[c4d.ID_USERDATA,193]

    if g_dirty_glass_presets == 0:
        g_scratches = 5.0
        print g_scratches

Thanks, PluginStudent!

I figured out a way to get this to work. They key is separating the User Data out of the RS XPresso node but still maintaining a connection to this node through a regular XPresso node. Cinema won't let me drag Redshift nodes from the RS XPresso window to the C4D XPresso window. Nor can I drag them from the AM.

The solution is to delete the User Data from the RS XPresso window, paste it into a new C4D Xpresso window, then use Set Driven (Absolute) on the RS nodes I need what is essentially double access to. Cinema then automatically creates a new XPresso node, which I then cut the contents from and paste them into my UD Xpresso node.

My only question is what is the difference between Set Driven (Absolute) and Set Driven (Relative)? Does it make a difference? Thanks.

I tried inputting the User Data directly into a RS port using Python and this code:

import c4d

def main():

    obj = op.GetObject()
    neon_col_INPUT = obj[c4d.ID_USERDATA,834]

    # List: Spline, Colour, Power, Gas, Blend.
    spline_UD = {1: 618}

    for item in spline_UD:
        rs_mat = doc.SearchObject ("S" + str (item) + " Gas")
        rs_tag = rs_mat.GetTag(c4d.Ttexture)
        rs_mat = rs_tag.GetMaterial()
        outputNode = rs_mat[c4d.REDSHIFT_GRAPH_NODES]
        gvMaster = outputNode.GetNodeMaster()
        gvRoot = gvMaster.GetRoot()

        colour = obj[c4d.ID_USERDATA,spline_UD[item]]
        print colour

        power = obj[c4d.ID_USERDATA,619]
        gas = obj[c4d.ID_USERDATA,65]
        blend = obj[c4d.ID_USERDATA,66]

        currentNode = gvRoot.GetDown()
        while currentNode is not None:
            if currentNode.GetName() == "RS Material":
                RSMaterial[c4d.REDSHIFT_SHADER_MATERIAL_EMISSION_COLOR] = colour
                break

Now my code causes C4D to hang. Can you help?

Cool. I will try a different approach. Thanks for all your help on this, zipit.

The original code yields image 1:

m, u yields image 2:

s, u yields image 3:

It doesn't look like any of the actual User Data Values (3 of which are colour) are coming through. Here are images of the node and the UD:


Neither m,u or s,u causes the actual User Data to transfer to the nodes before the User Data node gets deleted. Is there something I am missing?

Because data is coming from User Data, do I need additional info as per this post?

Hmmm. I tried to implement the code (fixed indent errors in the first def) and the print out looks like it is catching what it should but the User Data is not being copied over to the inputs before it gets deleted. Any idea what I am doing wrong?

    def get_port_descid(node, port):
        m, s, u = port.GetMainID(), port.GetSubID(), port.GetUserID()
        if u > 0:
            try:
                node[(m, s, u)]
                return (m, s, u)
            except AttributeError as e:
                pass
            try:
                node[(m, s)]
                return (m, s)
            except AttributeError as e:
                pass
            try:
                node[s]
                return s
            except AttributeError as e:
                pass

        return None

    for item in spline_id:
        rs_mat = doc.SearchObject ("S" + str (item) + " Gas " + str (bake_name))
        rs_tag = rs_mat.GetTag(c4d.Ttexture)
        rs_mat = rs_tag.GetMaterial()
        outputNode = rs_mat[c4d.REDSHIFT_GRAPH_NODES]
        gvMaster = outputNode.GetNodeMaster()
        gvRoot = gvMaster.GetRoot()

        currentNode = gvRoot.GetDown()
        while currentNode is not None:
            if currentNode.GetName() == "Neon Redshift":
                for out_port in currentNode.GetOutPorts():

                    connected_ports = out_port.GetDestination()
                    out_port.Remove()

                    c4d.EventAdd()

                    out_did = get_port_descid(currentNode, out_port)
                    print out_did
                    if out_did is None:
                        continue

                    for in_port in connected_ports:
                        in_node = in_port.GetNode()
                        in_did = (in_port.GetMainID(), in_port.GetSubID())
                        in_did = get_port_descid(in_node, in_port)
                        if in_did is not None:
                            in_node[in_did] = currentNode[out_did]

                currentNode.Remove()
                break

            currentNode = currentNode.GetNext()
