javascript - Three.js - sprite depths rendering backwards in r70+ -

it looks broke r70+ regarding z-depth of sprites.

here jsfiddle works perfect r69.

here same jsfiddle except using r71. can see when scene rotates, depths of sprites not shown correctly. half time rotated view wrong z-depths.

is bug or new need add missed?

i've tried variations of common commands below , nothing seems work around used to.

var shadermaterial = new three.shadermaterial({      ...     depthtest:      false,     depthwrite:      false,     transparent:    true });  particlesystem.sortparticles = true; 

i'm aware of new renderdepth, solution seems unrelated , doesn't explain why break previous behaviour. don't need continually update renderdepths manually camera angles we?

pointcloud.sortparticles removed in three.js r70; see this commit.

in original example (without transparency), can desired behavior enabling depth test material:

var shadermaterial = new three.shadermaterial({      ...     depthtest: true }); 

in updated example (with transparency), it's necessary sort particles in three.js r70.

note three.js still handles z-sorting when rendering three.sprite objects. worth investigating.
