Shader FX is a full-featured real-time shader editor for 3ds Max.
It allows artists with no previous programming experience to build
complex HLSL FX shaders for use in Maxs viewport and in external
game engines.

Build right into 3dsmax it offers a gradual learning curve to
.fx shaders for artists who are used to the 3dsmax material editor.

ShaderFXs powerful schematic interface lets you quickly assemble
shaders that support complex effects such as parallax mapping
fresnel fall-off and cube map reflection all by simply connecting
nodes together. Your shader progress is displayed and updated in
3ds Maxs viewport as you build the shader so you can always see
your results in real-time.

Once youre happy with your results you can use your shader in the
3ds Max viewport or you can also export your shader in the popular
HLSL FX format for use in other applications and game engines.
