When starting a fresh new project, there are a number of steps you need to do to get up and running rendering with ACES within RenderMan.

...

• When starting a new project, you'll need to select the ACES1.2 config from the OpenColorIO parameter in the Features tab within the Render Settings.  
  
  
• If RenderMan's Image Tool is already open from a previous Linear project, you will now have to close and re-open IT, to ensure you are now rendering within the new ACES color space.  
  If you are rendering within Maya's Viewportviewport, you will simply need to restart your interactive render session.
  
  
• When working with textures, RenderMan will now handle all the conversion needed to get your textures into the ACES color space.
   
  For instance, if you insert a Diffuse or Albedo color linear sRGB map into the Diffuse parameter of a PxrSurface, the Texture Manager will not only convert it to RenderMan's preferred file format (.tex) but will also automatically handle the color conversion to the ACES color space at the same time. 
  
  
• This is also the same for when you insert an HDRI map into the PxrDomeLight or when working with Normal or Bump maps.  Based on the rules defined, the Texture Manager handles all the conversions for you.
  
  
• You will are now also be working with ACES calibrated light temperatures and intensities., so feel free to increase the values higher to see one of the main visual benefits of ACES
  
  
• Whether you render within IT, Maya's viewport, or Maya's RenderView, you will are now be rendering within the ACES color space.
