Well I'm not using level-blocks in WED. I'm only using models for my whole levels. (some models have static-lightmaps)
I didn't test it, but I'm pretty sure just setting the LevelBlock's material to the lighting-shader won't work.
I've never written a shader for level blocks, but I think they work different.
If you want to use LevelBlocks you have to use the standart lighting.
The default engine lighting for level blocks shouldn't be that bad. by looking at specBump.fx it seems that blocks have their normal map on entSkin3 instead of entSkin2. Maybe creating a variant for blocks where the color map alpha is used for specular and entSkin3 is used for normal would work properly edit: I could get it working in blocks by commenting the define on line 13 (#define SPECULAR_ESKIN3) and in line 77 (inside NormalMapSampler) changing Texture = <entSkin2>; by Texture = <entSkin3>; Now if the shader could use color map alpha for specular it would be perfect

change line 163 to
float4 EffectMask = Color.a;
If you now uncomment #define SPECULAR_ESKIN3 (should be @line13) the alpha-channel of the color map is used as Specular-intensity give it a try!

Thats nice! Could you upload the modified .fx-file? Then I'll delete everything which isn't used anymore. (And I can use it, too  )

There are two variations of the original .fx, one which uses alpha as specular, and another one which I also modified for blocks ( just changing entSkin2 by entSkin3 in the NormalMapSampler ). In the scene there are two blobs, one is a model and the other one is a block. Download link: http://www.mediafire.com/?3wbdk4cwyex9pnj

Color.a = fAlpha; applies the Entity.alpha to the output color with this you can make the entity transparent when decreasing the .alpha value of the entity This line isn't wrong... (Colormap alpha isn't supported, yet) you set Color.a = fAlpha, but you never set fAlpha fAlpha is passed by the engine to the shader. It contains the entity.alpha value with the range [0-1]
