This really shows what your real problem is... If you own A7 commercial or pro you don't really need Sphere anymore
Then show me a level with parallax-mapping plus real-time soft-shadowing. Sphere was able to render this a few years ago. I did not see such a project from you, from Conitec or anybody else.
...but only if you know how to properly use it, same goes for the whole A7 engine.
So you say that all users of this engine don't properly use it? Otherwise we would see similar project like we can see on other engine forums.
I visit them all often when I do announcements. The world is not standing still.
But the ones that would fit into a 'next gen' demo as you would like to see are never free.
Ok, I understand. You will not create it. So you don't have to find more excuses.
If it really would be possible then somebody would have made it for the last "create something good-looking" contest. The best of the best did not make it. So I understand your situation

Which is mainly why a lot of us say that these kind of demos would theoretically be possible with A7 too.
And this little word "theoretically" is the point. There is no proof. Are all A7 users dumb or lazy? I don't think so. So there must be another reason for it.
I offered my help and my contents even for free to many users. I offered Slin (an experienced shader coder) complete model packs to make a few scenes.
I contributed textures, models and levels to some other projects.
But still I achieve something better in shorter time in other free tools like IrrEdit, C4 or in the demo version of TGEA as you can see at our Dexsoft page.
I would use A7 render images for advertising if they would be superior. I am no fanboy, I use what works best for me.
