$ssbump work not like it should in some places. (solved)

[r0nii]

im using the texture nature/blendrockgroundwall003 and mostly combined with nature/blendrockground005. but its really visible that those are not the same texture because the nature/blendrockgroundwall003 is lighter then the other one cause of the %ssbump in the script. But that not the problem. problem is that because of %ssbump the textures become darker in some places. big problem is that half of my skybox is dark. all props got already disabled shadow. i don't know what should i do.
is there a way to disable all shadows on skybox? or different way to fix this bug,glitch or thing?

edit: solved by making the lighting grid smaller and replacing some texture with the same texture but without $ssbumpmap.
