Hi iam owner of 3d gamestudio standard edition. I have one good project with my team,so we need engine. I have to choises : Upgrade to commercial or buy other engine (iam thinking about BV engine)

So please help me, can this engine make stencil shadows (without artefacts,solid FPS) , because iam read about problem with terain(please can someone explain me problem) . is solution to buy sphere engine too?

what about 3dsmax9 exporter? (iam seeing only to v6 exporters)

yes, it can make stencil shadows...

the sphere engine is a plugin for 3dgs with a lot of shaders..

I think there is a 3dmax exporter, but i dont know for which version of 3dmax...
Edit:
Oops, yes for 3dmax 6....
Omega

ok can you post me link for some showcase where someone realtime using moving light sources and object casting shadows to enviroment and other objects?

Well, take a look at this:

i wanted video or executable (i need to know something about performance,fps,max polygons,max light sources,shader problems)

Stencil shadows are possible with A6 Commercial or higher. I think they perform okay, but don't count on them being the fastest thing in the world - they aren'nt. As far as I understand it, A6 is not the reason for stencils not rendering that fast, though.
"Max polygons" is no value you could really ask for regarding modern game engines. The number of polygons that are viewable while still having a decent framerate totally depends on what you do with them: Are they textured or not, do they use shaders/FFEs, are they dynamic entities or static meshes etc.
Max. light sources is currently 8 lights at a time (not in the entire level!). Dynamic lights, that is - you can have an unlimited number of static lights. One of the next versions (currently beta) will support a new lighting management which allows for more dynamic lights.
As for shader problems, I don't know. Problems with shaders are usually related to the shader code itself rather than the engine.
