Same error here, the shaders do not compile:
: 0(16) : error C0000: syntax error, unexpected $undefined at token "<undefined>"
I've got it tested by several others. And it seems to work for some while not for others. I guess this is the curse of not using Unity3D/UE :(
Yes that's why we like to target HTML5, it is easier to support.
Does your solution support HTML5?
All right I've fixed your shaders, I'll make a PR
Thanks for your try, but then it fails on my system :P
I've uploaded a version that I now hope works.
