materials - reflective

How come when i apply a reflective bhodinut material to 3d text only the rounded edges can be reflective and the front facing camera view looks as if nothing is there...as in no material! can anyone help??? much appreciated thanks!

because the bhodinut materials are simulating multilayered materials and what you're seeing is the fresnel effect. if you just want something reflective then i would suggest using the standard cinema material (which i'd recommend anyway over the bhodinut shaders as you can do everything that they can do apart from anisotrophic reflections only with far more control and flexibility).

You can use an hdri or reflection map in the environment channel to get a faux reflection, but in the actual reflection channel, you need something to reflect, in which case you can add the same hdri or relect map to a sky object (or whatever) and make it unseen by the camera with a compositing tag, but still reflected by the material on your logo.

Shizzle, That looks about right.. there's nothing to reflect except the frontal light. You could load a texture into the environment channel, and sometime putting a slight bump map, the surface still looks flat, but has just enough of a bump to add some character to the reflections...

That's what I did for this gold logo (very slight bump)
