Verbosity Settings - Arnold for Katana

Specifies the verbosity for log messages.

AI_LOG_DEBUG

Show all information. Take care when using this mode as render times may increase.

Disable logging when rendering

Disables logging when rerendering.

max_warnings

Limits the number of repeated warning messages sent to the log.

Render Statistics/Profiling

An extensive set of tools that allow performance issues to be more easily identified and rendering processes optimized. A dditional timing statistics organized by both nodes and categories can be output to JSON files. This makes it possible to know which objects are most expensive to render and what parts of the renderer took the most amount of time. It also allows for detailed profiling visualizations by outputting trace information into a file, such as "my_profile.json", by calling AiProfileSetFileName("my_profile.json") or kick -profile "my_profile.json" , and then loading the JSON file in Google's Chrome web browser "chrome://tracing/" or into https://www.speedscope.app/ .

Render Statistics

Creates a JSON object for each render pass that gets collected in the stats file, with an increasing number for each pass placed into the file ("render 0000", "render 0001", etc). So if you are appending, the highest-numbered render group is the most recent one. Otherwise, with overwrite, it will only contain one object with the most recent pass.

Stats Mode

Create a filename and choose either "append" or "overwrite" mode.

Profile File

Output detailed profile timing information from the render to a file. Note that these files can be large.

Report File

Output a render statistics report to an HTML file. You can open this report in a web browser to quickly visualize and inspect detailed render stats such as frame render time, memory usage, render time by category or by node, and texture usage.

Leave empty to disable.
