@Dunhou
Thank you for your help, but after I run the following code, the Redshift Settings have not changed
By the way I am a python novice and the above code is written by GPT
I just want to use the script to change the Settings of the image below

I want to write a script to set the Settings of Redshift Matpreview
But

import c4d
import c4d.documents
import redshift
import os


def FindVideoPost(renderData, pluginId):
    vp = renderData.GetFirstVideoPost()
    while vp is not None:
        if vp.IsInstanceOf(pluginId):
            return vp
        vp = vp.GetNext()
    return None

def FindAddVideoPost(renderData, vpPluginID):
    vp = FindVideoPost(renderData, vpPluginID)
    if vp is None:
        vp = c4d.documents.BaseVideoPost(vpPluginID)
        if vp is not None:
            renderData.InsertVideoPost(vp)
    return vp

def main():
    doc = c4d.documents.GetActiveDocument()
    renderdata = doc.GetActiveRenderData()

    vprs = FindAddVideoPost(renderdata, redshift.VPrsrenderer)
    if vprs is None:
        return

    # Switch renderer
    renderdata[c4d.RDATA_RENDERENGINE] = redshift.VPrsrenderer

    # Set Redshift render parameters
    vprs[c4d.PREFS_REDSHIFT_MATPREVIEW_MODE] = 1

    # Refresh UI
    c4d.EventAdd()
    # print("Render settings updated to 4K and frame range set to All Frames.")

# Execute the main function
if __name__=='__main__':
    main()

vprs[c4d.PREFS_REDSHIFT_MATPREVIEW_MODE] = 1
This code doesn't seem to have any effect

Then I changed the method and set the code in C4D

import c4d
from c4d import gui

def set_amlimit_preference():
    # 获取全局设置容器
    bc = c4d.GetWorldContainerInstance()

    # 设置新的值为 666
    bc[c4d.PREFS_REDSHIFT_MATPREVIEW_MODE] = 1
    
    # 应用修改后的设置
    c4d.SetWorldContainer(bc)

    # 保存设置到磁盘
    c4d.SaveWorldPreferences()

    # 尝试刷新界面
    c4d.EventAdd()


# 运行函数
if __name__ == '__main__':
    set_amlimit_preference()

Can someone help me
