given my experience with vray, i hardly feel qualified to be reporting bugs. but after spending the past 3 hours trying to figure out why my image was not rendering properly, and finally figuring out how to make it work, i can only chalk this up to a bug in the program.
here is what was happening:
i have a scene with a series of vertical glass panels (serving as structural reinforcing for a curtain wall). the camera is positioned so that we are looking through maybe 8 vertical planes, then through the curtain wall and to the outside. i have some stainless steel columns outside the curtain wall. the columns should be showing a reflection of the interior space as well as an hdri map i have in their material environment slot.
when i render the view, the reflection on the columns is not showing up, it just renders as black (ie: my maximum reflection depth colour). so i figured it had to do with the max depth of the glass materials, right? so i increased both the reflect and refract max depth to 16, 24, 32, but still the reflections are black.
finally, out of frustration i enable the reflect / refract depth global override and set it to 32. voila! the reflections show up. i then lowered it to 24, 16, and finally 12, and the reflections are still showing up.
so is this a bug? or am i missing something?
i've attached 3 images, one showing the columns behind the glass, without the vertical reinforcing. the 2nd is how the reflection was showing up when i was experiencing the problem. the 3rd is the final solution using the global override.
again, i'd love to know if this is a known issue, or if i'm just missing something.
