Hi,
I wanted to ask, is there a way for this to be compatible with deformers or similar, I realized that the tag is not capable of drawing the location of the centers of each polygons altered by deformers, it is curious and I wonder if there is a way to solve it.
Cheers

Hi @i_mazlov ,
This solves my problem, for now I don't think I have another question, and I could consider my problem solved, thanks.

Hola @i_mazlov ,
Yes, it is true, DESCFLAGS_SET_USERINTERACTION does not work with layers, any other contribution to the problem is appreciated, from this I have no other doubt related to this topic, I leave the file here as an example.

Currently my problem would only be the issue of the lack of updating, because now I know that I can change the boolean of the layer with LAYER_S_PARAM_ALL_ACTIVE , but the lack of updating persists, I really don't know what could be causing it is causing.
code example, using the booleans of the layer:

import c4d
def main():
    doc = c4d.documents.GetActiveDocument()
    obj = op.GetObject()
    F = obj[c4d.ID_USERDATA,1]
    FM = doc.GetFirstMaterial()
    shd = FM.GetFirstShader()
    layer = shd.GetFirstLayer()
    i = 0
    while True:
        if layer:
            if i == F:
                #layer.SetParameter(c4d.LAYER_S_PARAM_SHADER_BLEND,True)
                layer.SetParameter(c4d.LAYER_S_PARAM_ALL_ACTIVE,True)
            else:
                #layer.SetParameter(c4d.LAYER_S_PARAM_SHADER_BLEND,False)
                layer.SetParameter(c4d.LAYER_S_PARAM_ALL_ACTIVE,False)
            layer = layer.GetNext()
        elif layer == None:
            break
        i = i+1
    c4d.EventAdd()

Hi @i_mazlov ,
I have another question and I want to take advantage of this situation to consult, I really also want to be able to change the float that measures the mixing force, (I also wanted to know how to access the rounding) and I could, but now my problem is that it really takes too long, because not to say that it does not react until I manually move this float.
Here is an example:

here the code (python tag)

import c4d
def main():
    doc = c4d.documents.GetActiveDocument()
    obj = op.GetObject()
    F = obj[c4d.ID_USERDATA,1]
    FM = doc.GetFirstMaterial()
    shd = FM.GetFirstShader()
    layer = shd.GetFirstLayer()
    i = 0
    while True:
        if layer:
            if i == F:
                layer.SetParameter(c4d.LAYER_S_PARAM_SHADER_BLEND,1)
            else:
                layer.SetParameter(c4d.LAYER_S_PARAM_SHADER_BLEND,0)
            layer = layer.GetNext()
        elif layer == None:
            break
        i = i+1
    c4d.EventAdd()

cheers,

Hi @i_mazlov ,
Excuse me for the lack of research, if I usually check if there were similar cases but I don't think I was able to understand it well, thank you very much for showing me these examples, they were really helpful.
the code you wanted:

import c4d

def ChangeTexturePathOfLayer(layer = c4d.LayerShaderLayer, Vector = c4d.Vector()):
    bmpShader = layer.GetParameter(c4d.LAYER_S_PARAM_SHADER_LINK)
    bmpShader[c4d.COLORSHADER_COLOR] = Vector
def main():
    mat = doc.GetFirstMaterial()
    if not mat:
        return
    shd = mat.GetFirstShader()
    if shd.CheckType(c4d.Xlayer):
        ChangeTexturePathOfLayer(shd.GetFirstLayer(), c4d.Vector(0.458823, 0.278431, 0.164705))
        c4d.EventAdd()    
if __name__ == '__main__':
    main()

I still don't know what c4d.LAYER_S_PARAM_SHADER_LINK does specifically
Well, within the documentation it is only mentioned that int is allowed as a parameter.

Hi,
Today I was trying to link or access the color within a sahder layer only with python, I know I can get it and change its parameter in the same sahder layer, but my question is more about how I can enter one of these and change its data , as in this case the color, or also the direction of a bitmap.

Hello @jferdinand,
Apologies for the delay, I examined your example some time ago and I suspect that it does not solve my problem, activating "frame-dependent" causes the update to stop, and it is present in animation again, my intention is to completely remove that delay, both in editor and in animation.

Any kind of help is appreciated.

I apologize, the translator does not help much, as I said, I created a spline chain, where the depth of its handles depends on the length of the spline, my problem was that when I did it with only xpresso, it showed errors when rotating, because it took time update.

thinking that the error was either hierarchy, the spline node, or how to order the xpresso I did the same thing but with a python tag, despite this the same problem was present.

import c4d
#Welcome to the world of Python
def main():
     spline = op[c4d.ID_USERDATA,2] # spline object
     length = c4d.utils.SplineLengthData(spline)
     length.Init(spline)
     Long = length.GetLength()
     op[c4d.ID_USERDATA,1][10004] = Long /3.783
     #[10004] = control depth 1 iKsplinetag
     op[c4d.ID_USERDATA,1][10014] = Long /3.783
     #[10014] = control depth 2 iKsplinetag
     length.Free()
     c4d.EventAdd()

And speaking of the number "3,783" I used it only for my purpose as it corrected the strength of the depth of the controls
