OctaneRender for Softimage 3.0Author: Stephan Woermann
Plugin V3.0RC2 released Oct 1st, 2017. Stephan Woermann AKA face continues his work on the Softimage integration of the unbiased GPU render engine OctaneRender. He recently updated the plugin to version 3 which features improved ICE integration, support for volumes and an upgrade to the latest OctaneRender core.

From the product page: [..] The release of the new OctaneRender 3, brings new state-of-the-art tools never seen before in any production renderer. Features include volumetric light field primitives and deep motion buffers for high frame rate VR rendering. The release also incorporates important industry standards for GPU rendering, including Open Shader Language (OpenSL) and OpenVDB for particle simulation. Use OctaneRender to create images of the highest possible quality at speeds up to 50x faster than CPU-based, unbiased renderers. Attached to your editing tools? No problem! Octane supports more than 21 plugins and has a fully interactive, real-time 3D editing viewport. And with Octane 3.0 we provide integration to a beta version of the new Octane Render Cloud to scale for all of your on-demand GPU compute needs..

A bundle with the (required) OctaneRender will cost $509, for OctaneRender owners, the plugin itself is $139. A demo is available here. Documentation is available here (yet to be updated to version 3). Many more details and videos are available on the forum pages linked below.

Very interesting quote Draise i always believed that 'unbiased' was a little bit unfit term for these progressive renderers (that improove a frame till infinity), but now the term makes more sense.

I can see now for example that Redshift claims is 'fully biased' because of that non progressive mode where you can bias the result with samples for all individual parts (like for example the samples for the glossyness of x material). On progressive mode it overides all the individual samples and is just another unbiased renderer.

On topic, im happy that companies still consider Softimage users, i will check out the new Octane.

No you're wrong of course in progressive mode RS takes the sample weight into account !

Biased means you're getting a biased render, a renderer who takes shortcuts to makes the final image where some parts are interpolated and tend to be close to his homologue unbiased one but not really the same.

A good analogy would be a blurred reflection to get rid of the noise, you're close to the "right result" but not the same.

This is the Iradiance Cache modes, and RS fall in an unbiased where you set the renderer to Brute force raytracing

I believed the same, but someone corrected me in the forums, in the docs is more clear:
When progressive rendering is enabled, certain renderer features and options have no effect. These are:

All unified sampling settings (including filtering)
Subsurface scattering. Redshift's SSS implementation is computed as a separate pass so it's only available to production (non-progressive) renders
Photon mapping (including caustics). Redshift's photon mapping implementation is computed as a separate pass so it's only available to production (non-progressive) renders
Irradiance cache, irradiance point cloud. These are not needed because progressive rendering computes GI in a brute-force way.
All parameters that have to do with "number of samples". Examples include the number of samples for Depth-Of-Field, number of samples for glossy reflections or refractions, number of area light samples, etc.

Was really impressed as well. I expected it would slow down above a few thousand hairs, because Octane uses tube geometry.

I like the look of the rendered images compared to redshift, I runned some test some times ago, same HDR same geo ;-)
The plugin is not so advanced than RS thought...

True, although comparing the plugins isn't fair at the moment. Octane's API itself is limited to building one big node graph using a rather limited set of nodes. It seems to be closer to Maxwell, where photo realism is a priority, at the expense of a lower degree of user control.

Hi,

Here are a few clips from Stephen showing some of the supported things as they came out,
(from 3 weeks, to a year ago)


Octane4Softimage V3



Part9
Deformation motion Blur (Exaggerated)



Part8
VDB's, in this case imported from Houdini,
and probably therefore also suppports ExplosiaFX generated (standard) VDBs



Part7
"RenderMapping" Ao ... Reflections... uv coords.... ... etc ..



Part6
Render Channel support (AOVs)



Part5
Custom "Render Layers"



Part4
RenderRegion Support
Enhanced Environment Shading
and use of "Medium" (fog?) shading.



Part3
Procedural "Daylight" environment shading




Part 1 & 2
Object (and full scene MB from cam motion) motionblur,
and visible BG environment shader.



Intergration seems quite complete, and looks really fast!

Also, Deformation MB and custom AOV support seems to cover the remaining production critical aspects.

While Rendermapping and VDB Support remains definately welcome and not by any means minor features.


Seems a little pricey though, maybe would they consider pricing relative to the "prevented from being sold" status of Softimage (?) :ymdaydream:

RC2 just released: https://render.otoy.com/forum/viewtopic ... 0&p=322340


FIXED:
  • ICE Particle Orientation from Euler Rotation is now correct.
  • ICE Point Segment Size wasn´t used, which is fixed.
  • Swapped the "Tonemap Type" under the Misc settings.
  • Motionblur is now working correct with subframes.
ADDED:
  • Added support for deformed motionblur.
  • Added parameter for deformed motionblur subframes.
  • Added parameter to enable deformed motionblur for each mesh in the mesh properies.
  • Added scene for motion blur.
  • Added scene for deformed motion blur.
  • Added scene for texture baking.
  • Added Octane materials to Get -> Material
CHANGED:
  • Changed default Point Segment Size from 0.0025 to 0.025.
  • Changed the kernel in the render layer scene to info channel / render layer id, to show the layer colors .

with these additions (and quoted posts below), that sounds like pretty good ICE integration..
I'm soo curious!

Yes it works :)

ICE support is okay. Strands work and ICE instances and volumes do too which are the two most important bits. Attributes are not supported, for transferring color you have to do some trickery with additional UV sets.

No instance shape animation tho like Arnold, and you probably couldn't do advanced trickery like this (Arnold too)

Octane is very fast though, and the ultraphotorealistic maxwellian look =P~

ongoing development: Hair uvws, new environment options..

https://render.otoy.com/forum/viewtopic ... 443155f028

Also, not sure how it's done, but it's now possible to bake a texture and then use the same texture inside the same tree

Ambient Occlusion mappable Environment shader
Great for speedy(-er) fake Env lighting exterior shots (among other things)

      Image Image

Rasterisation of Procedural gererators
to allow proceduraly drive displacements.
