Hello,

I want to share my latest arch viz project. I want to ask you if you also have this impression that Octane Render make renders not that sharp? I mean they seem a little lower quality than other very know commercial biased render engine starting with letter "V" :P

Or maybe I should set the filter in pathtracing options to 0?
Any ideas.

Of course when it comes to hotpixel removal I know that I can render picture 2 times bigger and then resize it in photoshop with blurr, but I would like to achieve crystal sharp picture. Is that possible right now with this 1.0 beta 2.46b version?

This is something I asked myself as well.

Renderings getting sharper when you turn "aperture" to zero in the camerapanel.
But still not so sharp as in the renderer with "V" :-)


Kind regards

Thank you Alain, this is so simple straight from real life - how come I didn't think about aperture :) thanks a lot once again. :)

Where can we ask on this forum about more things to come with full version of Octane like:

Index of refraction - Can we count on fresnel not only for REFRACTION BUT ALSO FOR REFLECTION?

Regards,

I'm not so sure.

Fresnel is something that we know from unbiased renderers.
I guess because of the physical correctnes of Octane "Fresnel" is computed automaticly and you don't have to think about it.

But I may be wrong...

Kind regards

That's correct. Physical fresnel effect is computed functions of the material properties.

Sounds Amazing but seems ok just for specular where there is and IOR. For diffuse and glossy there is computed fresnel automatically based upon what? .. color? ... IOR depends on chemical properties of substances that material is made of :) so how can it be computed automatically? How octane "knows" if Im making wood material or concrete or clay? :)

BTW Maybe it's the topic for different forum? :)

I guess you can just forget Fresnel parameters.

Or can you show me an example where Octane computes wrong reflections ?

Kind regards

Hey,

The fresnel is computer according to the IOR of a specular material.
