du brauchtst bloss in der "specBump.fx" folgendes ändern:

sampler sBaseTex = sampler_state { Texture = <entSkin1>; MipFilter = Linear;};
sampler sSkin2 = sampler_state { Texture = <entSkin2>; MipFilter = None;};<<<-NONE zu Linear
sampler sSkin3 = sampler_state { Texture = <entSkin3>; MipFilter = None;};

you need only the "specBump.fx" change the following:

sampler sBaseTex = sampler_state { Texture = <entSkin1>; MipFilter = Linear;};
sampler sSkin2 = sampler_state { Texture = <entSkin2>; MipFilter = None;};<<<-NONE to Linear
sampler sSkin3 = sampler_state { Texture = <entSkin3>; MipFilter = None;};
