问题
When using normally three.js I get this error at Firebug:
gl.getProgramInfoLog() (54,6): warning X3557: loop only executes for 1 iteration(s), forcing loop to unroll
Even all the rest looks like working properly and not giving any problem.
Trying with some examples from the net I see the same error message, you can find it for example at some examples in the net like this one
When it uses three.min.js appears at line: 537 and with three.js it appears at line: 25909.
