I am importing a model that consists of multiple individual meshes. Right after import (where everything is selected), I want to rotate the imported selected objects based on a [X, Y, Z] angle parameter. Also I want to run the script as a blender "--background" shell process.
I tried doing something like this but it doesn't seem to work.
bpy.ops.transform.rotate(value=math.radians(param.x), orient_axis='X');
bpy.ops.transform.rotate(value=math.radians(param.y), orient_axis='Y');
bpy.ops.transform.rotate(value=math.radians(param.z), orient_axis='Z');
I get this error:
RuntimeError: Operator bpy.ops.transform.rotate.poll() failed, context is incorrect
I tried searching the internet for solutions but I couldn't understand exactly what is going wrong. Also I think this error doesn't appear because I am running with "--background", but because I am running it as a terminal command.
Thanks in advance! I am using Blender 2.9.
Im running the same issue. I have some scripts that worked so fine in blender 2.83 as module using bpy.ops.transformm.rotate, now this is not working on the new bpy (blender as module) version 2.93.
I realized that bpy.ops.transform.rotate.poll() return false using the module, from python script, while the function bpy.ops.transform.translate.poll() returns true.
However when I run the same function in the scripting console of the blender 2.93 GUI, the function bpy.ops.transform.rotate.poll() returns true.
So I think is a bug in the new version.
However I was able to fix this passing a VIEW_3D context as first argument in the operator:
>>> ov=bpy.context.copy()
>>> ov['area']=[a for a in bpy.context.screen.areas if a.type=="VIEW_3D"][0]
>>> bpy.ops.transform.rotate(ov)
{'FINISHED'}
In your case:
# ... already selected objects, ov is for override, I'm lazy.
>>> ov=bpy.context.copy()
>>> ov['area']=[a for a in bpy.context.screen.areas if a.type=="VIEW_3D"][0]
>>> bpy.ops.transform.rotate(ov, value=math.radians(param.x), orient_axis='X')
{'FINISHED'}
