| Tutorial 6. Lighting Your Scene and Using Materials. For mental ray renderer. |
rendered together you get some odd reflection or something but this will
depend entirely on the model you are building and the exact positioning of any
illumination.....but you get the drift.
So that's it for the materials as far as I'm concerned, under just this one
light.....and with GI turned 'On' it's not too bad....so now we can turn our
attention back to the lighting, and see if we can't jazz this baby up a bit!
One thing to consider here is reflections. Now this is not as in a 'mirror' or
'water' but as in illumination. We know that from the material we selected for the
'Wood' that it is varnished......well that makes it kind of shiny then, but as you
can see there is not much evidence of anything being shiny......but WE know it
IS. It also has a 'Bump' map for the grain too, which is dependant on the
position of any light to be seen. So how do we show that then?
Well to see light reflected off a surface our point of view, the object and the light
source all need to be in a particular place. As in a 'mirror', we don't see a
reflection if the 'mirrored' surface is pointing away from us.....stands to reason.
We don't really want to change our view of the object, nor move the object, so
only one thing left we can do...........lets move the light....................................
