I'm having a problem allocating the multipass layers on the server side in NetFrameInit(). I want to add
a grayscale layer (for a Z-Depth multipass), but that doesn't work as I expect it to. The z-depth layer on
the client-side has a colors-per-pixel value of 1 (as I expect it to). These are allocated in
VideoPostData::AllocateBuffers() (i think?).
Now, NetFrameInit() seems to be handled pretty differently and I have to go over the procedure of
allocating the multipass layers once again with a different interface (the MultipassBitmap ). Unfortunately,
the Z-depth layer that I allocate always has a colors-per-pixel value of 3.?? This is the output that I get:
@ Client Layers
Z-Depth CPP: 1
GI CPP: 3
Normals CPP: 3
CPP: 4
@ Server Layers
Z-Depth CPP: 3
GI CPP: 3
Normals CPP: 3
Background CPP: 4

Any hints are highly appreciated. Thanks,

Thanks again Andreas! I now use VPBUFFER_POSTEFFECT for normal
