Heightmap Terrain flicker

[Colin]

i will most likely just implement a quad based render queue

EDIT

maybe you can help me out with something?

i'm fairly new to HLSL and i've ran into a difficulty... rather than hardcoding my alphamap scaler value i want to automatically stretch the alphamap across the whole terrain automatically.... any ideas how i can accomplish this? I was thinking of 2 options....

1: divide 1 by vertices of the terrain, so 64 vertices terrain = 1 / 64.
2: add an internal semantic into my effect loader to grab the dimensions of the model.

what do you think?
