Obtain a performance file by:
<ol>
<li>Make sure scene uses Babylon MAX.</li>
<li>Add the temporary Javascript line <em>window.alert('Turn on Performance Recording')</em> just prior to Engine Instancing line.
<li>Load the scene, turn on performance profiling, &amp; click ok to the temporary alert.</li>
<li>Do anything that might call code in babylon.js not yet encountered.</li>
<li>Stop recording, and save the data as a file.</li>
</ol>
On this page:
<ol>
<li>Select the branch to build the config against. <em>Be sure to change to that branch in repo</em>
<li>Select File with 'Browse' button below, and pick the file saved from above.</li>
<li>Make any changes of name to babylon file names &amp; directory..</li>
<li>Click Generate. Tip: change Firefox Option for Downloads to <em>Always ask me where to save files</em> to avoid having to move config with custom entries to Gulp Directory.</li>
<li>Copy the 'custom.cofig.json' file generated in Downloads directory to the Gulp directory.</li>
<li>Run: 'Gulp build-custom' then test with scene. Tip: test with the generated max version.</li>
<li>If need stuff did not get recorded in performance file, then select file(s) &amp; click Generate again.</li>
</ol>
