Hi,

I tested to spawn a couple of objet whit moderate complexity shape and add these shadow whit shadow_stencil = 1;

wow... i falling to 23 fps... is the engine are really bad at running shadow or i do something wrong? Before i put the shadow i runned it at 560 fps...

im pretty sure its not my hardware : im running it on 2x AMD Radeon HD 6870 in crossfire.

So if i want to make a decent quality game , better to change to another engine?

If you want a decent quality game, don't use stencil shadows. What version do you use? Shadow mapping is the way to go.

This is not a general rule, stencil shadows can be better in some situations. But you need to have a clue what shadows are and how they work, otherwise you will fail with all engines and never make a decent quality game.

Stencil shadows are normally better when you have few shadow throwing objects and when you use LOD stages. When many objects need to throw shadows and when you don't have LOD then PSSM shadows are the better solution.

For decent shadows you need the Commercial edition because the free trial version only supports nonaccelerated shadows and they are slow.

Look in the shadow chapter of the manual there is everything explained.
