Object Smoothing

I just downloaded this demo tonight and was testing it with some .OBJ files I created. The models were low poly and I could see some faceting of the faces (redundant)

...anyway, I subdivided a couple of times in my 3D app and still noticed faces when rendering. Does Octane offer any mesh smoothing or do I need to import overly high resolution models to get better/smoother results?
Thanks...love the renderer BTW.

Just click on the material with the material picker and toggle the "smooth" option at the bottom of the material stack.

Worked like a charm. Thanks Greg!

I'm having trouble getting my model to "smooth" correctly in Octane. Here's a series of images and what they look like.
1. Is in Octane with the Smooth setting checked
2. Is Octane with the Smooth setting unchecked.
3. Is Lightwave 10
Do I have to import the .obj a certain way from LW10 or is there something in Octane I need to setup?

It seems to be a problem with the lightwave plugin. Radiance promised to comminicate this to the plugin developer, Hopefully this will be solved any time soon. Just have to wait.

The above shots look like a problem I encountered in other apps previously - when you export a model with a subdivision smoothing modifer applied (nurms or otherwise) it isn't applied to the output .obj file...
The solution is usually to collapse any modifiers into a higher poly mesh, I'm sure there's a way to do this in lightwave - it seems to me that it is exporting the model pre-subdivision. Not being a lightwave user I'm not sure the command for that, but I'm sure there is one, it will result in a single high poly object that you can then save out in whatever format you need.

Coild this be a problem associated only with the Demo version of Ocatne? I'm thinking of purchasing the beta, could it possible fix this issue?

No, it's a problem of the exported geometry. Octane doesn't modify geometry. I.e. if you export incorrect geometry, Octane renders incorrect geometry. What are the OBJ export options in Lightwave you have?
