Here is a little add on for you all to merge into the Shader Variance Editor (SVE).
Material menu > SVE > Merge...
It contains most of the MForge pre-sets. All you have to do is drag the preview icon from the SVE into your material channel and you're away!
This gets round the lack of a preview when browsing your material folder because the SVE saves the shaders own preview rather then the material ball.
It also removes the 'locate this texture' nagging that you get with material loads, so just set up your reflections and drag on the shader!
If you are new to the SVE, hold down space to scan vertically through your shaders, hold down shift space to turbo charge the drag. The MForge shader icon is a grey sphere.
Any probs, let me know,
