This is actually Unity related, not rly a Playmaker issue, plz forgive...
Without changing lighting/rendering/build settings, in my latest web build the normal and spec maps no longer work. I went back to an earlier build and the maps have now stopped working on that one, too. It looks like crap now. I've tried on different computers with upgraded and not upgraded Unity web players. I saw someone had a similar issue w/ ANdroid builds and I used his suggestion of adding a directional light that had NDE.
Someone else MUST have encountered this.
