Updating from 2.5 to 2.6: the following warning gets logged thousands of times:

THREE.WebGLRenderer: Trying to use 31 texture units while this GPU supports only 16

This happens, regardless of the layers present in the scene. It even occurs with an empty GlobeView

My Environment

  • Version used: 2.6
  • Browser Name and version: Chrome 71.0.3578.98
  • Operating System and version (desktop or mobile): Windows 10
  • Graphics Card: NVIDIA GeForce GTX 750

Steps to Reproduce (for bugs)

  1. Open one of the provided itowns examples and take a peek into the console (given a GPU which does not support more then 16 texture units).

There was a double callings of WebGLUniforms.upload with uniformsNeedUpdate.
It rolls out a double allocation of uniforms and therefore an overflow of webgl capabilities texture units.
