Thank you for letting me know @m_adam

Thank you so much @m_adam !
I try to texture_baker example just now you mentioned! Adding some options with BaseContainer()

        bakeData[c4d.BAKE_TEX_AMBIENT_OCCLUSION] = True
        bakeData[c4d.BAKE_TEX_AO_VERTEX_MAP] = True

It's working but I want to make a vertex map tag into the selected object like the below image.

It's automatically generated when I click the bake button in the Bake texture tag(blue) with my hand, but I don't know how to do it with python code.

This is code that simplifies and adds options.
Finally, I got the bitmap so Can I use a bitmap to make the Bake texture tag into the object?

import c4d

class TextureBakerThread(c4d.threading.C4DThread):

    def __init__(self, doc, textags, texuvws, destuvws):
        self.doc = doc
        self.textags = textags
        self.texuvws = texuvws
        self.destuvws = destuvws

        self.bakeDoc = None
        self.bakeData = None
        self.bakeBmp = c4d.bitmaps.MultipassBitmap(512, 512, c4d.COLORMODE_RGB)
        self.bakeError = c4d.BAKE_TEX_ERR_NONE

    def Begin(self):

        # Defines baking setting
        bakeData = c4d.BaseContainer()
        bakeData[c4d.BAKE_TEX_WIDTH] = 512
        bakeData[c4d.BAKE_TEX_HEIGHT] = 512
        bakeData[c4d.BAKE_TEX_PIXELBORDER] = 1
        bakeData[c4d.BAKE_TEX_CONTINUE_UV] = False
        bakeData[c4d.BAKE_TEX_SUPERSAMPLING] = 0
        bakeData[c4d.BAKE_TEX_FILL_COLOR] = c4d.Vector(1)
        bakeData[c4d.BAKE_TEX_USE_BUMP] = False
        bakeData[c4d.BAKE_TEX_USE_CAMERA_VECTOR] = False
        bakeData[c4d.BAKE_TEX_AUTO_SIZE] = False
        bakeData[c4d.BAKE_TEX_NO_GI] = False
        bakeData[c4d.BAKE_TEX_GENERATE_UNDO] = False
        bakeData[c4d.BAKE_TEX_PREVIEW] = False
        bakeData[c4d.BAKE_TEX_COLOR] = True
        bakeData[c4d.BAKE_TEX_UV_LEFT] = 0.0
        bakeData[c4d.BAKE_TEX_UV_RIGHT] = 1.0
        bakeData[c4d.BAKE_TEX_UV_TOP] = 0.0
        bakeData[c4d.BAKE_TEX_UV_BOTTOM] = 1.0
        bakeData[c4d.BAKE_TEX_AMBIENT_OCCLUSION] = True # HERE I ADD
        bakeData[c4d.BAKE_TEX_AO_VERTEX_MAP] = True # HERE I ADD
        # bakeData[c4d.BAKE_TEX_OPTIMAL_MAPPING] = c4d.BAKE_TEX_OPTIMAL_MAPPING_CUBIC

        self.bakeData = bakeData

        # Initializes bake process
        bakeInfo = c4d.utils.InitBakeTexture(self.doc, self.textags, self.texuvws, self.destuvws, self.bakeData, self.Get())
        self.bakeDoc = bakeInfo[0]
        self.bakeError = bakeInfo[1]

        if self.bakeError != c4d.BAKE_TEX_ERR_NONE or self.bakeDoc is None:
            return False

        # Starts bake thread
        self.Start(c4d.THREADMODE_ASYNC, c4d.THREADPRIORITY_BELOW)
        return True

    def BakeTextureHook(self, info):
        # Texture Baker hook, currently not used
        # print info
        pass

    def Main(self):
        # Bake Texture Thread Main routine
        self.bakeError = c4d.utils.BakeTexture(self.bakeDoc, self.bakeData, self.bakeBmp, self.Get(), self.BakeTextureHook)


if __name__ == '__main__':
    obj = doc.GetActiveObject()
    uvwTag = obj.GetTag(c4d.Tuvw)
    tags = obj.GetTags()
    textags, texuvws, destuvws = [], [], []
    for tag in tags:
        if tag.CheckType(c4d.Ttexture):
            textags.append(tag)
            texuvws.append(uvwTag)
            destuvws.append(uvwTag)

    textureBakerThread = TextureBakerThread(doc, textags, texuvws, destuvws)
    print textureBakerThread
    print textureBakerThread.Begin()
    bmp = textureBakerThread.bakeBmp
    if bmp is None:
        raise RuntimeError("Failed to retrieve the baked bitmap.")

    # Displays the bitmap
    c4d.bitmaps.ShowBitmap(bmp)

    # Removes the reference to the C4D Thread, so the memory used is free
    textureBakerThread = None

Thank you for your time @m_adam !

Hello, I am a newbie in c4d python programming.
And have tried to bake BakeTextureTag by script.

Like below..

if __name__ == '__main__':
    tags = doc.GetActiveTags()

    for i, tag in enumerate(tags):
        c4d.CallButton(tag, c4d.BAKETEXTURE_BAKE)

The problem is how to know when the baking is done??

I'd like to bake one by one. Because I baked several things at the same time, my computer goes down

I've seen some examples of threads. It's too hard, and it's just showing me the uvw tag bake not BakeTexture Tag.

Please give me some advice.

Thanks.
