Parallax Occlusion Mapping...

[Deu sex]

Yes! That solved the problem. Just use
RayLinearIntersectionSM2(aHeightMap, vHeightMapPos, vEyeVec);
instead of
RayLinearIntersectionSM3(aHeightMap, fSteps, vHeightMapPos, vEyeVec);
in
core\shaders\deferred_gbuffer_solid_frag.glsl, line 147
and all problems disappear.
The only difference between two functions is fixed step instead of adaptive step.

Men
