Thanks for looking at this. Does this main that it is at least on the "to do" list again?
Does it still work in c++

Dear community,

is it possible that the method c4d.modules.mograph.FieldInfo.Create() is (currently) bugged ie from 2024 onwards?

As an example:
I took this script from

import c4d
from c4d.modules.mograph import FieldInput, FieldInfo, FieldOutput

def fieldlist_sampling(op, doc, poslist, fields):

    pCount = len(poslist)
    sample_flags = c4d.FIELDSAMPLE_FLAG_VALUE | c4d.FIELDSAMPLE_FLAG_COLOR

    fieldInput = FieldInput(poslist, allocatedCount=pCount)
    fieldInfo = FieldInfo.Create(sample_flags, None, doc, 0, 1, fieldInput, op)
    fieldOutput = FieldOutput.Create(pCount, sample_flags)

    fields.DirectInitSampling(fieldInfo)
    samplingSuccess = fields.DirectSample(fieldInput, fieldOutput.GetBlock(), fieldInfo)
    fields.DirectFreeSampling(fieldInfo)

    return fieldOutput



def main():

    count =5                                        
    distance = 225    
    fields = op[c4d.ID_USERDATA,1]

    null = c4d.BaseObject(c4d.Onull)

    if not count:
        return null

    div = ((count-1)/2)*distance
    poslist = [c4d.Vector((distance*c)-div,0,0) for c in range(0,count)]
    samp_list = fieldlist_sampling(op, doc, poslist, fields)
    # samp_list._value


    for n,p in enumerate(poslist):
        cube = c4d.BaseObject(c4d.Ocube)
        cube.SetRelPos(p)
        value = c4d.utils.RangeMap(value=samp_list._value[n], mininput=0, maxinput=1, minoutput=20, maxoutput=150, clampval=False)
        cube[c4d.PRIM_CUBE_LEN] = c4d.Vector(value)
        cube[c4d.ID_BASEOBJECT_USECOLOR] = 2
        cube[c4d.ID_BASEOBJECT_COLOR] = samp_list._color[n]

        cube.InsertUnder(null)

    return null

It is for a python generator with a field list in user data (id=1), field list contains a linear field.
When the field is moved the cubes change size and colour, the script is not perfect, it's just to demonstrate.

The generator works on 2023 and below but not in 2024 and above
This it the running in 2023:

and this is 2025
