OTOY Forums

Ok, hope everybody will post here all the info we need to know for how to use octane to render animation. I have few questions:


1) Does Octane renders 1920 x 1080 HD resolution?
2) Does Octane saves alpha channels?
3) Does Octane saves render phases?
4) How much faster is Octane ?

I wanna do a test. This image rendered in 2 hours using lightwave 3D on an i7 computer. I will provide the model if someone can render it in Octane to show here and say the rendertime.



May someone render it to me?

1) Yes. You can change the image resolution to whatever you'd like.
2) Yes.
3) Don't know what this is, sorry.
4) Depends on your GPU. I'd expect speed increases of at least 10-15 times (at the time I upgraded, I think I got something like 20 times faster).

Octane currently lacks a few features, SSS being one of them. You wouldn't be able to get the same look on the face as in the image you provided. The rest of it would render easily though.

without area lights and no image maps randering time in lightwave is 5m 38s only for 1920x1080 HD image.

I'm adding the OBJ file to a link so someone would be able to apply phisical materials and render it on octane.

same setings on MODO only 3 minutes 16 seconds for 1920 x 1080 HD image

please someone do a test on Octane

please download only if you will render on octane due to download limit

1. Yes.
2. Yes.
3. If you mean render passes (e.g., AO, specularity, shadow, etc), then no.
4. I wouldn't necessarily say that Octane is faster than other software out there. While it is very fast (depending on the GPU(s) that you have), it offers other things that are truly innovative (such as near-realtime rendering and photo-realistic results).

Your .obj must come with a .mtl file, else it's not importable in Octane.

Hi,

The renders from lightwave and modo posted above are rendered with simple ray-tracing / specular reflection.
There is no indirect / global illumination or even ambient occlusion used.

As octane is a physically based renderer and works with at least ambient occlusion in the directlighting kernel (the fastest preview mode),
it will not do a render in a few seconds, as the ambient occlusion, soft shadows for area lights and glossy reflections require time.
If we did support a classic raytracing style kernel it would be really fast, probably 30-40 seconds, as computation would be highly parallel.

However it will probably be able to render a frame like this with all these effects using the directlighting kernel in 4-5 minutes at 1080p.
If you were to use the same alghorithms on a cpu based raytracer, it might take 20-40 minutes per image. (eg without using any interpolation techniques like irradiance cacheing)
It depends greatly on the GPU(s) used though.

Radiance

Thanks for reply

Actually in Lightwave and Modo I'm using full montecarlo radiosity.

Modo had less tima to render due to no glass material applyed.
The difference in lightwave from 2 hours to some minutes when removing textures is probably due to multilayers materials and HDRI imaging.


Need see the rendering time on Octane
