For Maya software renderer only.
The
Render Diagnostics tool lets you monitor how well you optimize the scene for rendering and watch for limitations and potential problems that may occur. For example, surfaces that are far away or blurred may not require the same level of visual accuracy or photo realism as surfaces close to the camera. You can speed render times and reduce memory usage if you know what the renderer is doing.
Run
Render Diagnostics after you adjust objects and before you render to obtain valuable information about how you can improve performance and avoid limitations. You can run the diagnostics while experimenting with rendering settings, or before you start the final rendering.
To run render diagnostics
- Do either of the following:
- From the main Maya window, select
Render > Run Render Diagnostics.
- From the
Render View window, select
File > Render Diagnostics.
Maya opens the Script Editor and displays a list of potential problems in the scene.
Sample diagnostic messages
The following are some of the diagnostic messages Maya software rendering displays:
- Motion blur and raytracing are both turned on. (Reflections, refractions and shadows are not motion blurred.)
- You have motion blur turned on. Be aware that particles, lights and shadows do not motion blur. As well, motion blurred shadows may produce artifacts.
- You have specified output to the Quantel format. In previous versions of Maya, this format only outputs to NTSC/PAL/HDTV resolutions, and does not output to fields. If the above restrictions are not met, rendering defaults to PNG image output.
- You have specified output to the Cineon format. This format does not render out a mask channel.
- You have specified a fractional animation by-frame step. This results in images over-writing each other for fractional frame counts. Remember to turn on the modify-extension.
- Near/far clipping values are too far apart. You may encounter numerical imprecision resulting in incorrect renders.
- There are no renderable cameras in the scene.
