Trying to do simple motion blur but only get a black screen

Hi, I’ve made a fiddle of the issue:

I’m using GitHub - vanruesc/postprocessing: A post processing library that provides the means to implement image filter effects for three.js. on top of three.js.

I posted on stackoverflow but may have more luck here :slight_smile: Any help greatly appreciated plus if you have some tips on postprocessing with three.js I would really help me as I’m only beginning with these postprocessing effects! Thanks !

Here is a solution with plain three.js:


Waw, thanks a lot ! I’ll go study this in depth right now :slight_smile:

am i missing something?
