   Panda3D vs Unity Comments

   Positive comment by rdbotic · May 9, 2019

   Panda3D is open-source and has excellent support for scripting in Python, making it a great choice for rapid prototyping.

   Negative comment by Guest · Jun 22, 2019

   The renderer is very bad and outdated. The development of the engine is very low.
