has anyone a nice shader for phongLighting+normalmapping

here is a very nice example…with source code and binary

with up to 5 point lights + directional light + and many surface material setting…i think it would be cool to have it in DX11

i tried it … but just had that binormal and tangent issue! if anyone is down - lets go!!!

mio

Here is a function you can use without binormals and tangents. Has some artifacting but at least you can use it with generative meshes.
