About W Hair and Ornatrix ( Tips and Tricks questions)

[mojave]

But still the same problem on the standalone right because we have to choose the type of hair as "hair length" so the option to have random hair doesn't work anymore how to make work bouth?
on the standalone random color and the ramp color along the hair? because the option "hair length" and "segment count" can't be set by texture on the shader so how to do it a random colour can we have a example scene on standalone please? maybe is me I don't see one other way to add the random please any help?

Hair gradient interpolation type just affects to how the W texture is mapped to hair strides. However, I am not too sure what you mean by making it work both. You could potentially use a mix texture with a noise as one of the inputs, and a gradient on the one. While the gradient is affected by the setting you select, the mapping of the other input remains unaffected.

Sorry I didn't understand I will give a try later.Do you may to set a orbx to download so we see the connections please?

cheers,

So, a new test with W coordinate and gradient with my old hair =)

I already share this material in a LiveDB. Materials =>Organic => Skin => Hair Colored Gradient

Nice! Thanks for sharing!

Hello, dear OTOY Team.

So I have a few problems with Ornatrix and Octane =)

1. I cant render gradient hair by strand index in Octane and Ornatrix.

Here is my material and render.

octane_example.jpg

And here is the scene to your tests --- >>> SCENE

This an example with Vray and the same gradient =)

As you can see - An each strand have red or blue color. How I can realize this in Octane???

2. I can't render a normal map in Octane + Ornatrix.

Here is an example with Vray Normal Pass.

When I selected Geometric Normal - I see this...

3. I can't render tangent normal in Octane + Ornatrix.

When I selected Tangent Normal - I see this =)

tangent_n.jpg

When I selected Vertex Normal - I see this =)

vertex_n.jpg

Here is an example with Vray and a right tangent normal =)

I hope those screenshots will help and you will fix this bug in the new version.

Best Regards, Andrew.

Hi Andrew,
here is what I get with c4d hair:
1. multicolor hair with gradient:

2. geometry normal:

3. Tangent Normal

4. Vertex Normal

Hi, bepeg4d.

I used 3dsmax and Ornatrix. And have this bugs with Ornatrix + Octane... Btw you have wrong tangent normal =)) I showed the right example in Vray... You can open my 3dsmax + Ornatrix+Octane scene which I attached to the early message with this bugs =)

Hi Andrew,
sorry but I don't have nor 3ds Max nor Ornatrix.
Do you mind to export to Standalone and share an.orbx?
thanks,
ciao beppe

Hi guys,
I think Octane 3dsMax + Ornatrix has some issues.
I tried to export to SA and issues seem to be too.

Then there's no point, because I work in 3dsmax + Ornatrix + Octane and want fix of this bug =)) Because I can't work and record my tutorials with Octane and should use Vray for this =))
