Solved "Hidden buildings under terrain" with terrain cover assets.
I've been imported all the assets of "Terrainpack" folder from the old FPSC.
You just change (add) the scale options and set the "materialindex = 0" to hear grasses sounds.
Also, I've used "NoTerrain()" plus "NoWater()" for increase at 120-140 fps game frames.
In this video appear smaller fps's because the "Fraps" screen recorder program use a lot of video resource too.
See in the attached photos the real speed (fps) without "Fraps" program.
Smile today, tomorrow could be worse
