When running the addon, This error has occurred, how do I fix it? I am running it in 3dview, I don't know why the context is incorrect.

  • $\begingroup$ good question, i have tried and couldn't figure it out, there is a solution using the deprecated context object but that does not work for blender 3.2 and above blender.stackexchange.com/questions/95793/… $\endgroup$

  • $\begingroup$ just switched the order of commands, It worked. This means that the command has to be placed before the specific camera is called,A little strange $\endgroup$

  • $\begingroup$ cool you resolved it, so i guess it does not need to be in the VIEW_3D context? $\endgroup$

  • $\begingroup$ Strangely, I think it needs to be in the VIEW_3D context and needs to be in camera perspective, so I put the code for camera perspective at the top c.space_data.region_3d.view_perspective = 'CAMERA' ,then call the specific camera. if this order is wrong, the code will not run. Thank you again for your code. $\endgroup$
