Thanks you all
I solved all the problems but I did not multiply by 2 particles.
The blows that makes ultra realistic effect and I am proud to say that thanks to the LUA scripting Corno_1 "SnowBoxV2" and "RainBoxV4" come out in a few hours today!
For SnowBoxV2 it's just that I focused the 3D object to the player's cursor and I also sunk into the ground the snow like that more worries !!
I also remade a lively texture rendering 64 frames for ultra-realistic (1K to 4K texture total).
Same for "RainBoxV4"; I did the same thing as SnowBoxV2 but in addition I redid all the textures 64 animated frames: the texture is now in Ultra High Definition (
4K to 16K total to 220MB for texture) !
The RainBoxV4 takes about 20 to 30 seconds to display in the editor GameGuru but do not worry it is absolutely
not reduce FPS 
Out of these 2 new improved within a few hours (with video demonstration) !
I hope that these latest changes will appeal you: it will be the last free version designed for GameGuru because we will work on other things ^^
For those who do not visit the forum regularly and I would put the SnowBoxV2 RainBoxV4 also later on the Store GameGuru free to make it accessible to everyone
EDIT : Rectification: Finally the texture will RainBoxV4 2K to 8K total to avoid future incompatibilities with GameGuru if it passes DBP to C ++ in the months / years to come.
