hi,

my biggest problem when i am using a multi-terrain-shader is the framerate and the distant parts of the terrain.

the framerate is about 10 frames per second and the distance doesn't look good at all...



because you all seem to have good experience with shader-programming, what about this:



a shader that only shows the detail-textures when the camera-position is at a specific distance.

beyond this distance (the grey area in the example) you would only see something like a ground texture for example:



and for the detail-stuff:



just as example.

the a6 engine uses a very similar system with a command like "detail_size=32", but only one detail-texture can be used and without the blending in the distance.

Has anybody an idea, how to build a awesome shader like this?

your terrain would have another lighteness in the distance. i think it'll look kinda ugly
but why do you use 4 (!) detail textures? one or two are far enough to my experience.

the first textur of the hmp should cover the whole hmp once.
beaches or paths are already on this skin.
the others are detail-textures which turn the background-color of the first texture more dark or more light.
like the old detail-stuff from a6 (or maybe already a5 i am not sure anymore).
in the distance the detail-textures should dissappear to lift up the framerate...

i think a shader like this would help a lot of people who have got problems with the framerate when they number up the camera.clip_far and i hope this shader can lift the framerate.

have no idea.sorry man
