Trace reflection/refraction

[glorybound]

Trace reflections - if this is off, reflections will not be traced, even if the reflection color is greater than black. You can turn this off to produce only highlights. Note that when this is off, the diffuse color will not be dimmed by the reflection color, as would happen normally.Trace refractions - if this is off, refractions will not traced, even if the refraction color is greater than black.

I am not sure I fully understand this. When I turn it off the speed is amazing, but the results are poor. When I turn it on, which his default, the results are as expected, but long render times. Is there a balance?

it can't be balanced because it can only be on or off. all you really do if trace reflections/refractions is on is play with the depth and cutoff values, maybe also trying to use the 'dim distance' for reflections.

You would normally switch these off for distant plants
