MR intro, Dynamics, D.Instancing

Maya Optimization: I watched this tutorial. However, I couldn't render it and make it, because Maya couldn't  find and then couldn't render textures normally. I tried to reload them and still nothing. To be honest, the whole project file didn't work normally. Anyway tutorial is clear and I have the idea.

MR Shadows: This time I managed to reload all textures and Maya allowed me to make render. Only once :(

Dynamics. 

Couldn't batch render first 2, because of this: Don't know how to fix it. I'll try reinstall Maya, but only by the end of this week.

Instancing. V.helpful tutorials.
