Visualize outputs a png with just the background

SOLIDWORKS Rendering - Visualize - Photoview

I am using Visualize Standard 2020 SP5.

I am rendering with a PNG output with a transparent background. Sometimes it works and creates the image. Sometimes it completes without error but the file is empty. There is nothing but the transparent background. What am I doing wrong?

Just is case someone else ever has this problem.

MLC figured it out. I was running with a time limit that was too short to get a first pass in. So the output was a blank file. When I switched to a number of passes there was a rendering in the output file.
