Notes About Reducing Render Time Out of 3D software

To Reduce Render Time One Can:
   - Reduce poly Count
   - Bake Light And Ambient Occlusion for non moving Objects
   - use Light Linking
   - looking into Shadow Size
   - using image plane where possible
   - Rendering In layer
       no need to render a BG for 300F when the camera, light and the object not moving ONLY the characters are. Just render one frame then comp it later.
   - Consider Compositing in the workflow

there are many other little settings in the render option or in the shader option could help to reduce the render time.
