Thanks!

@tuarrep Did that fix it? I tried loading one of your wrl files and I'm getting this:

The jsm module probably needs an update first.

[mrdoob]

I updated it. And now webgl_loader_vrml is failing.

@tuarrep are you able to investigate this?

[Mugen87]

@tuarrep Contributions should always be tested with existing examples. It's not acceptable to introduce a breakage. If you can't manage to fix this issue, the PR has to be reverted.

@Mugen87

It's not my responsibility to merge. If it breaks, revert it, no problem.

@mrdoob I can investigate, I need some time to do so. As the patch was written in January, I need to recall all the details.
I've a working patched code on a project, I'll test on it.

[mrdoob]

It's all good! I'll revert in the meantime.
