Weird PLSplattingShaderLit problem.

Something wrong with lighting. Here are screenshots:

This seems to me the right one:




and this is broken:



Scene ambient is set to 0,0,0,1
Light diffuse 1,1,1,1
Terrain lighing is switching between those two states while moving and rotating camera.
Material and shader files are original.

Am I first to meet this problem?
It seems like a half of the map isn't processed with PLSplattingShaderLit. But when you move a little then lighting falls directly under the light-source(that yellow "star" on picture is attached to light position) or sometimes terrain is again half-lightened, but somehow different.
Where ever I move my light source only one half of terrain is lightened.
Terrain LOD isn't changed between those states, and material lod doesn't seem like the reason too.

Light type is: Point
Attenuation: range-1024, const-1, linear-0.01, quad-0

You'll have to debug shader that comes with that material.

Ok, that was my bad actually. It took too much time for me to realize, that I had to add VertexNormals=yes to config file.
But still lighting is not really smooth. It's like discreet, like black or white on low resolutions. Maybe I could just turn all vertex normals to (0,1,0)? What is the simpliest way to do so?

don't use vertex normals, use normal map and you'll get LOD independant lighting. (per pixel lighthing instead of per vertex.).

PLSM2 CVS also has a new way to LOD so that it goes from highest to lowest independantly of tile roughness, try it.
add

RoughnessLod=no

to you terrain.cfg
