Surface settings question.

[Godstrike]

Does anyone know how Octane interprets standard Lightwave textures?

I have a material which I want to replicate inside the Octane node editor.

When the nodes are not activated the surface renders as in the attached file, but I can't seem to replicate the look inside the Octane node system.

To be clear, Octane is rendering it's interpretation of Lightwave material settings which I want to use and develop inside the node editor.

Any help or insights would be appreciated:)

The LighttWave material and the layered textures that you have inside can't be used with Octane. You need to build a material in the node editor using only Octane nodes.

There is a tool in the Octane material nodes "Get T Texture Layers" that can help. It will extract the texture in the "T" layers of the standard material, linked to the Octane material. This tool usually helps to convert scenes.

Hi Juanjo,

It's a bit tough to explain, but let me try again.

In the attachment Octane is rendering a material in the IPR -- if you look at the material the node is not activated.

So my question is what settings are being used to render this material? Is there a formula that Octane uses to convert the LW material to an Octane material?

Thanks!

Ahh, yes, sorry. Some basic parameters applied over an Octane glossy materials are extracted from the standard LW material if nothing is linked in the node editor (The diffuse, specular, roughness and transparency color values, as far I can remember), but the texture layers are not used at all.

No problem:)

So given the settings in the LW material (outlined in red), do you know what the corresponding node settings would be in Octane (that are being extracted from the LW material)?

I want to base a texture off this material, and can't seem to recreate the look.

Thanks!

Using a Glossy material node, you should be damn close with settings similar to this: Diffuse color of 0,0,0 -- Specular color of 10,10,10 -- Roughness around 50%

I see what you are trying to understand though, and have wondered myself; exactly what does Octane give a material, beyond Color, when nodes are not enabled... Default must have some glossiness, and some high roughness, like above. They never appear to be dead flat like Diffuse materials...

[juanjgon]

Yes, a Octane glossy material should be enough to simulate this kind of shading.

If you don't have any Octane material nodes connected, Octane builds a glossy material using the diffuse color, specular, roughness and transparency parameters of the LightWave surface editor.

It's interesting because every once and a while Octane kicks out a cool material from the LW settings

Thanks for the feedback guys.
