i downloaded the pythonscript to export my blenderanim to renderman. copied the scripts as told to blender and pressd alt-p as the additional help file told me to do.
and nothing happend … mhm.
i tried this with blender creator 2.23
Look at the terminal window to see what error messages you’re getting from blender/python. In windows a dos box/terminal opens when you start blender, blender prints error messages there. On linux/unix systems you have to start blender from terminal window command line to see the error messages.
A couple of questions: Do you have python installed? Do you have the python path set in blender?
i set the path typing “import sys” + “print sys.path” and then the path appeared in dos shell
then i executed with alt-p and it workd, but the rendered pict is black but in blender i can see it rendering with F12.
another blend file i tried i got following script errors:
traceback (most recent call last):
file “renderman.py”, line 57, in ?
file “renderman.py”, line 14, in writeCamera
AttributeError: ‘none’ object has no attribute ‘lens’
Ok you imported sys then it worked. Did you set the path to python in Blender, in the top header, right above the AutoTempSave button? You can see it render with f-12, is that the render that is black, or when you save it? It seems the most common cause of a black render is not having a light on the scene.
