When we utilize an EffectComposer, the scene is rendered into either composer.renderTarget2 or composer.renderTarget1. In a particular example, I came across this:
renderer.render( scene, camera, composer.renderTarget2, true );
renderer.shadowMapEnabled = false;
depthPassPlugin.enabled = false;
// postprocessing steps
composer.render( 0.1 );
I am curious about the impact of the first line in this code snippet. The scene is rendered into composer.renderTarget2, but how is renderTarget2 utilized thereafter?
Appreciate any insights on this.
