I wondered something about the feature list of 2.0 with regards to Blender, just technically:

- Can region rendering even make it into Blender? I don't think it has such a feature even for its internal renderers etc, so I wonder how this would have to be implemented?
- A similar thing for fur ... not sure what's needed there to make it work 1:1 between Blender and Octane
- Edge refinement/subsurfacing: I guess those are features, that aren't needed, as blender does that itself with its own modifiers? I was a bit confused on those features
- Displacement: That is probably easy to implement with the right nodes

Blender has region render, fur and displacement built in.

Thanks good to know .. didn't dabble much with the native renderers there.

I believe that the blender plugin actually has a semi "faked" render region, so hopefully it wont be a hard incorporation.

I'm looking forward to the hair particles to make better rugs. Scattering geometry doesn't always work perfectly.

Yes, Blender has Displacement, but not Micro-displacement ! Displacement is done before rendering (it is a modelling-animation feature done with a modifier) Micro-displacement is done at rendering time in the render engine : it is like a 2D displacement of rendered pixels. Blender internal and Cycles don't yet have Micro-displacement... except if I missed something recently.

Put a bump map into the displacement pin on the materal node, i'm not sure if that's what you're talking about, but it sounds like that. (Cycles only)

I will check, but I fear that it is simple Bump mapping. With real Micro-displacement, you see the relief on edges of objets.

So displacement maps in Octane 2.0 wont move vertices, but will move pixels?

I confirm that in cycles, it is simple Bump mapping when an image is put into the displacement pin of the material output node.

If it is Micro-Displacement, I would say yes, but I may be wrong. It may also add subdivision levels to the model at rendering time. I don't really understand the response of Abstrax :

Is it Raster displacement or Vector displacement?

Abstrax answered :
I guess it's what you would call "raster displacement", i.e. the placement is not done per vertex, but at a specific resolution in UV space (which is user specified).

Hi ROUBAL, Cycles can use true displacement, it is hidden in Experimental render settings.
