Title: Issues with tranparency
Post by: gaboflr on April 20, 2016, 11:32:35 PM
Hey guys I really need help, I'm making a citric squeezer and  all the elements  that are on the inside of the bottle when I place a transparent plastic material appear in black, I tried to move in the advanced options but I'm a newbie and I don't know how exactly how to make the elements on the inside to appear on the material that they are supposed to be.

Hey gaboflr-

Under the Lighting tab, make sure Global Illumination is enabled, and that  Indirect Bounces is set to at least 1. Also, increasing the Ray Bounces to between 10-16 (sometimes more, depending on the specific material) will yield a more realistic result with transparent materials. As a side note, it appears that your model is intersecting the ground; try moving it up in Y by a fractional amount.

Normally this is fixed by using two sided in material properties and or number of bounces in the lighting settings

This is correct concerning the Glass material (it will even render correctly without Two-sided enabled). However-  Glass (Solid), Liquid, Advanced, Dielectric, Gem, and Plastic (Transparent) materials, all need Global Illumination enabled for correct rendering, in my experience.

thank you so much guys, I couldn“t find the two sided tab or part in the advanced materials, but it was fixed just by changing the lighthning to global, it worked perfectly, I'm so grateful with you, I was ina hurry! ;)

You're very welcome...glad it helped. The Two-sided option under the Properties tab is not available for the Plastic (Transparent) or Advanced materials which you were using; it is specific to the standard Glass material.
