Hair Params not passed to Octane

Anyone know if I can pass frizz and other parameters to Octane for rendering? Nothing I try has worked...

Hello

All works. If splines - add octane object tag and Curves From Strands operator

I'm using deformers after Guides From Mesh operator or if add chaotic-artistic view - next after Hair From Guides

I didn't get that at all. Let me put this another way: what DOESN"T migrate to Octane?

Have you use last nightly build?

To render splines from Ornatrix, you need to add Octane object tag with turn on Render As Hair in Hair tab and add Curves From Strands operator from ornatrix fur/hair object.

Or if you render poly hairs, add Mesh From Strands operator from ornatrix fur/hair object  and octane material

About deformers like Frizz, Curl and etc. look at picture

What about the parameters from the hair shader? do those go across to Octane as well?

arghhhh, i do not know, wait ornatrix developer. I see that not used. Or ask Otoy developer to support material somehow

Octane does support the hair material (same one that you create with Ornatrix.) However, the settings don't seem to go across to Octane (they do with C4D internal hair.) 

I downloaded the nightly build and I have a better understanding of adding the modifiers into Ornatrix, so I think I have enough to build on now, thanks. 

sorry, i do not like Octane. I saw that it supports c4d native hair object. But not hair material!

try such with native hair renderer

 

or native

Sadly, the file that I was working on cannot be reloaded into Cinema after saving the file and shutting down Cinema. It appears that the file is now corrupt, and the only thing different is Ornatrix... :(

The file had both an Ornatrix object and a Cinema hair object (as I was testing both). A file that just has Ornatrix loaded fine. Curious.

Hi!

Unfortunatel I don't have Octane here to test, but would be really helpful to understand what can Octane render as hair so we can generatethe same kind of object. I'm attaching a scene with 4 different splines, can you test which ones Ocante can render?

Also, I need to know the ID of the Octane Object tag. To do this, please drag the tag to the Command Line ( Open Console, Advanced, Command Line...), press ENTER and get the output from the Python console.

Hello Roger

You can use demo of Octane, imho

c4d.BaseTag object called 'Octane ObjectTag/Octane ObjectTag' with ID 1029603
OctaneObjectTag[c4d.OBJECTTAG_RENDER_AS_HAIR] = True
OctaneObjectTag[c4d.OBJECTTAG_RENDER_AS_HAIR] = 1
OctaneObjectTag[c4d.OBJECTTAG_HAIR_TIPTHICK] = 1.0

and splines render with tag

All of them? That's good, Ornatrix hair should render too.

What's the conditions where you can and cannot render Ornatrix Hair in Octane?

 

I'll try the demo. Let's hope my macbook drivers will support it, because RedShift does not work.

But last build does not work with c4d hair mat and octane 4. That's problem

Deformed spline in Ornatrix enviroment by c4d hair material settings does not render by octane

We use the standard C4D material to render curves. At this moment, the only parameter we change on the material is the Width, all the others will be applied over the Ornatrix Hair. So Ornatrix Frizz is competely independent of the material's Frizz. If the material's parameters are affecting Octane, that's a Octane issue.

@jayroth commented that Octane does support the hair material, then probably thats the case and you need to use an Octane material.

arghhh, i'm not fan of octane. i want to help to make product better ;)

I show Jay ornatrix deformers
