Thanks for replying guys.
@Enrico: I'll check that material option to see if it makes any difference.
@Radiance: It's great to know clipping options are planned. Indeed this model is considerably large and you need to get a bit far away to see it completely
I was wondering if it would be possible to have a regular model viewing mode (wireframe, shaded, textured), without any unbiased render calculation going on, so you could manipulate your model easily and once you got the view you like switch to the unbiased engine and start the render calculation. I think it would be a great addition to Octane

Edit: I just checked the grass material's smooth value and it was unchecked by default. Radiance has done a great job reading the materials created in blender; they all export with their properties intact
