Adding Layers to a MultipassBitmap
-
Sorry folks, I keep spamming my topic! I've realised there's another issue. AddLayer() returns NULL, and from a topic I made previously (some time a go now) it was reported as a bug, but it's never been fixed by the looks of it.
How can I add layers to a MultipassBitmap!? How does the command Render to Picture Viewer do it?

Hi,
If you want the layer and folder to be displayed in the picture viewer you need to define the parameterMPBTYPE_SAVE
to True.
MPBTYPE_SHOW
is defined by default to true when you add a layer.
This parameter will just disable the layer as seen below. (the red eye)
This example will create a folder with a layer in it and another layer below the folder.
If it is working with pyhton, it should work with c++, you can share a bit of your code so we can reproduce it.
from typing import Optional import c4d doc: c4d.documents.BaseDocument # The active document op: Optional[c4d.BaseObject] # The active object, None if unselected def main() -> None: mpb = c4d.bitmaps.MultipassBitmap(640, 480, c4d.COLORMODE_ARGB) folder1 = mpb.AddFolder(None) folder1.SetParameter(c4d.MPBTYPE_NAME, "folder") folder1.SetParameter(c4d.MPBTYPE_SAVE, True) layer1 = folder1.AddLayer(None, c4d.COLORMODE_ARGB) layer1.SetParameter(c4d.MPBTYPE_NAME, "layer1") layer1.SetParameter(c4d.MPBTYPE_SAVE, True) layer2 = mpb.AddLayer(folder1, c4d.COLORMODE_ARGB) layer2.SetParameter(c4d.MPBTYPE_NAME, "layer2") layer2.SetParameter(c4d.MPBTYPE_SAVE, True) c4d.bitmaps.ShowBitmap(mpb) if __name__ == '__main__': main()
