Hey guys,just started learning Python and stumbled on a problem what is apparently a bug. When I render the image with my script and show it in the picture viewer, the resulting image is just black.
Here's the script I use:
import c4d from c4d import bitmaps, documents doc = documents.GetActiveDocument() rd = doc.GetActiveRenderData().GetData() res_x = 512 # image resolution x res_y = 512 # image resolution y bitdepth = 8 # image depth bmp = bitmaps.BaseBitmap() bmp.Init(x=res_x, y=res_y, depth=bitdepth) documents.RenderDocument(doc, rd, bmp, c4d.RENDERFLAGS_EXTERNAL) bitmaps.ShowBitmap(bmp)

Hi pelZ,
The bit depth in your code is not correct.
Cheers, Sebastian
bitdepth = 24 # image depth

Hi Sebastian,
that fixes the problem. Thanks!
But why is it 24 (16 and 32 seem to work as well)?Ciao,

16 bit works fine as well but the image has a lower quality.

When you render an Image "with 8 Bit" it is 8 Bit per Channel, not the overall bitdepth.
There are 3 Channels. (RGB)
3 * 8 = 24With Alpha, there are 4 Channels.
4 * 8 = 32Higher Bitdepths per Channel:
4 * 32 = 128Cheers, nux
