Hey Guys... i use keyshot for jewellery rendering.. anyway i have 2 problems:
#1. how can i eliminate shadows, for e.g i render a tiff with alpha channels... i get the image but there is always shadow behind it and it takes allot of time to delete it in PS5...
#2. And however i try.. like almost all the setting i have tried still the metal looks unnatural and the stones look dead.. i know its possible to achieve better results as i saw them on different sites and videos..
please help))
#2 : Rendering of stones depends a lot from HDR. You have to play with different HDR to find the good results. Avoid diffuse lights. The second important parameter is ray bounces. Must be increased.
Hi,
#1 - You can turn off ground shadows in the environment settings.
#2 - Like Arnaud said, you must find the HDR's sweet spot. Another trick is to render a pass for the metal and a pass for the diamonds. This way you can focus on one material at a time and bring them all together in PS.
Thnx Alot guys... lol i used hours of searching and didnt notice the Ground Shadows option..))
I often use two seperate HDRIs, one for the diamonds and one for the metals. I also like to tweek the KS diamond material and lower the abbe number which gets more colors in your diamonds.
Abbe Number-How Much Color is created when reflected in the diamond (lower the number adds more color)
