comparison photo vs. render
« on: December 30, 2012, 08:05:07 am »
i tried to make the same setup as the photo on the right.
with just the hdr editor i found it difficult to create the
the black cards on the sides because even if you use a negative
light you cant block a positive light next to it, i would be nice to be able
to import png files in layers. i modeled the black cards instead.
what freaks me out most is that i cant seem to find a glass setting that
fades the color in the thinner walls of the glass AND doesnt create this weird colord base...
maybe my settings are all wrong does someone have a clue ??

cheers

Make sure you are using solid glass (not just the thin glass). To match the photograph the lighting has to be precise as does the modeling. I think the glasses are thinner near the middle compared to the top and bottom.

The color of the glass is determined by the thickness of the glass. If the base of the glass is too dark compared to a reference photo that means that somehow the glass is too thick.
