I am trying to render clear acrylic in PV360, but so far I have not really reach any result I am satisfied with. Since 90 % of the product we make is from this particular material it is a frequent request. I saw there was an old topic on this, with old versions, and also not really answerd, so I give it another shot. Using SW 2013.
While searching the internet for help I found the solution for the rendering software Keyshot:
Use a Gem stone material, or dielectric material:
Refraction index 1.5 (1.489)
Abbe number 34 (this option I cannot find in PV360)
And then increase raybounces to something between 20-64 (depending if there is still black spots on the edges.
See attached picture for inspiration, that one is created in Keyshot with above settings.
Your help will be appreciated!
