Learn about opacity and specularity in Arnold.
- [Narrator] To render a liquid mesh in Arnold,…use the AI standard surface material.…There are a few other settings that we need to change…in order to render transparent materials.…In my scene I've got three versions of the liquid.…Here's the liquid layer…on which we find the original particles.…We're not rendering that now.…If we try to, we'll get an error message.…So let's turn the visibility off for that liquid layer.…We have the mesh layer but it's disabled…because we also have a mesh cache layer.…
That's what we're working with.…Leave visibility on for that liquid mesh cache layer…and set the current time to frame 120,…which is a representative frame.…That might take a moment to load the mesh cache in.…Select the mesh in the view port…and open up the attribute editor to the mesh shape node.…Open the Arnold section.…Very importantly, disable the opaque attribute.…The opaque attribute is enabled by default…as an optimization for the ray trace engine.…
If you want to render transparent…or refractive materials in Arnold,…
