Renderman Buckets in Maya

 I learned about Renderman in my undergrad when working on Delivery.  It has become one of my favorite renderers to use in Maya because of how it works but also because it's what Pixar uses to render their films.  I'm very inspired by Pixar.  In this post I just wanted to talk about buckets.  You often see buckets when you are rendering an animation and it takes a long time.  They have a big impact on how quickly and the order of where the scene will start to render.  In this post I'm going to talk about how to change the bucket size and how to change the bucket order.  

How to change bucket size:  First you need to know that the bucket size effects the blue boxes on the IPR if you have them visible.

The first step to changing your bucket size is to open your Renderman Settings, this could also be your rendering settings.  In the popup click on the Renderman tab next to the Common Tab.

In the Advanced tab in the Render Options tab you will find Bucket Size. Click the down arrow to select a size.  The reason you want to change the size is because for certain outputs it makes a difference.  It takes longer for a scene that is large with a small bucket size to render.  Changing this also has an effect on Batch Renders and Final Renders.

Since we understand how to change the bucket size when we need to,  how do we change the order?  Changing the order of your rendered scene does not effect your rendering, it's more so for your own preference.  

To start this, you need your Renderman settings open.  If you already have it open, then you're good.  Then in the popup just click Renderman next to the Common tab.  In the Render Options tab you will find Bucket Order.  Click the down arrow and select your preference.
