i found some feature of es3.0 that i like to have, such as occlusion query (a better object3d.wasVisible() function)
is it possible to enable es3.0?
It's up to you which version context you enable at startup. You should be able to setup 3.0 and still use jPCT-AE's 2.0 calls on it. You have to do the 3.0 calls yourself, of course. jPCT-AE doesn't make use of 3.0 and I actually don't plan on doing so, because nothing in the engine needs it.
i see, thanks.
