No render to texture -> no postprocessing, no real reflections and no shadowmapping.
There are NO realtimeshadows at all in the free version. The one that offers these features is to be honest quite expensive. Mac and Windows support is nice, but everything else also costs quite some money. And I somehow didn´t yet understand the sence in playing in a browser as it is anyways downloaded, it can only happen that I have to download it again and again instead of only once. But okay, that is probably just me as it is pretty common these days.
I btw didn´t find anything about multiple rendertargets, but I guess that they exist in the pro version?
At least featurewise A7 Comm is still the best choice. However the developement is very interesting at the moment and I am of course also very interested on how it goes on. I think if GameStudio would get new editors and templates, it could get just awsome and again interesting for everyone wanting to develop games.
