I’m quite new to blender and I recently undertook the project of modeling a glass of water. I took two cylinders and subtracted the larger from the smaller one to create a cup. Another smaller cylinder placed within the larger one serves as my model for water.
I followed this tutorial for instructions on creating clear glass (except for the part about Raytracing and Buffer Shadows): http://wiki.blender.org/index.php/Doc:Tutorials/Materials/Clear_Glass
When I render my model, I get the following result: /uploads/default/original/3X/1/9/1994b2fb8aa3019dcaa8ffc1a7460c4e041c50e3.jpgstc=1&d=1281075010
First of all, there are black splotches which are altogether unacceptable… What are those all about (I have changed the depth for transparency to 7)?
Second of all, I chose red as the colour of the cup, but if its transparency fresnel=5, shouldn’t the red be completely invisible? Why can I still see it?
Thank you very much for your help,
