Viz Render Log

• Name:VizRender_<timestamp>.log

• Purpose: Provides information on current status of Viz Engine.

Viz Trace Log

• Name:VizTrace_<timestamp>.vlog

• Purpose: Provides command trace that facilitates playback for error reproduction, contains at most the last 500 commands.

Viz Gui Log

• Name:VizGui .log

• Log Description: Each line in the log file has six components or entries, each separated by pipe (|). A typical log-line looks like:

The components for each log-line are:

• Date/time

• Type, one of:

  • LM_STARTUP (Regular startup)

  • LM_QUIT (Regular quit)

  • LM_QUIT_TIMEOUT (Timeout quit)

  • LM_QUIT_LOGIN (Login canceled)

  • LM_CFG (Restart with configuration)

  • LM_ENG_GUI (Restart engine with GUI)

  • LM_ENG (Restart engine without GUI)

  • LM_ART (Restart of Artist)

  • LM_ (Current mode restarted)

• Pid (Process id)

• Viz version

• Mode:

  • CONFIG (Config Mode)

  • NOGUI (Engine Mode)

  • NORMAL (Artist Mode)

• Starting on GPU<x>, for example GPU1 (Graphical Processing Unit number one)

Viz Shaders Log

• Name:VizShaders.log

• Purpose: Provides information on shader compilation.

Viz Console Log

• Name:Viz_<timestamp>.log

• Purpose: Logs console output to a file when the engine is started without console (-C option).

Create Log Files with Log and Clog Commands

The output of the Viz Engine can be redirected to a file using the command log <filename>, for example, log c:\temp\my-engine-log.txt. Note that the log file has no content until the Viz Engine in-memory buffers are flushed, meaning written to disk. The log memory buffers are flushed to disk either when the buffer are full or when Viz Engine quits. You can force the buffer to be written to the log file on disk by sending the command: CONSOLE FLUSH

You can take an immediate snapshot of the Engine’s current in-memory log with the command "clog". A new log file is immediately written to <viz data folder>\VizRender-ID.log The ID in the filename is the GPU ID, making it easy to differentiate log files in a Dual Engine setup for example.

Both the log and clog commands can be executed by sending them to Viz or by entering them directly in the Engine Console window.
