Thanks laugh
Yes these are pointlights.

I put a lot of stuff into this shader grin - actually everything I know at the moment, from triplanar texture mapping to colored ambient lighing
(threre are currently 33 #defines for all the settings...)

On the screenshot I'm mainly showing the specular reflections.

They are calculated with the lyon-algorithm.
It also supports a phong, a blinn-phong, a torrance-sparrow and a trowbridge-reitz specular calculation.

I saw them somewhere on the internet, converted them into hlsl and optimized them.

If you like the specular lighting, I can share the code with you wink
