Okay, I made the change with the blur and it looks quite a bit better now (the Light is even a bit further away than on the previous pictures) and I also tried to use an other algorithm for the shadowthrowing which got very similar to the first one...^^:
Thank you frazzle but I still feel as an absolute shadernoob
@Loopix: There are just some problems with bmaps in C-Script which made me unable to include water. And I wasn´t able to translate the code to Lite-C without the shadows not working (matrices and Lite-C -_-)...
This uses one view for the light and a second view for the camera (I could get rid of it, but it would take me some freedom I don´t want to lose at the moment
(easy combining with other shaders like normalmapping)). The shaders shouldn´t slow the rendering down too much, so just decide on your own how fast it is. This scene runs constant with 50-60fps.
I don´t really understand what you mean Nems-_-
Thanks for all your comments
