Rendering with DummyVecEnv

[Marianoetchart]

Hi I would like to render with DummyVecEnv but I get an error back saying it has not been implemented from baselines/common/vec_env/vec_env.py. How would I go about to implement rendering. Here is the traceback, any help would be appreciated:

Traceback (most recent call last):
  File "examples.py", line 473, in <module>

Unfortunately I don't know. I assume it will be easy, you can just delegate the rendering from subprocess to the main process.

Figured it out, thanks for the quick reply!
