OTOY Forums

I thought I would write to see if there has been any movement on adding any of Modo's procedural textures into Octane? I have been baking textures into maps, which has been working well, but it would be nice to be able to remove that step in the process.

Hi Fred - no change with this. It will require TheFoundry to build in support for plugins to be able to access the procedural shader bitmaps.

Also, has their been any though as to if the clear-coat channels will be integrated? When clear-coat bump and clear-coat roughness were introduces they really helped in building more realistic lacquered materials.

I have been using mix materials to get a similar effect, but I sometimes I want to default to on-the-fly conversions

It's not something I've investigated. If you have a sample scene showing the Modo and Octane material layouts, and the conversion rules (ie. Modo Material property XYZ = Octane Material pin ABC) I can see if it can be coded into the plugin.

Hi Paul,
I will send over a scene with a shader that does what I am hoping to do in Octane. The main function of the clear-coat channel I rely on is the ability to create 2 distinct specular lobes with varying fresnel values. This is how I have been able to make something look as though it is heavily lacquered.

I have noticed the fresnel values do not work identically in Octane as they do in Modo. I have been trying to substitute falloff maps to create similar effects. Is this correct? If not, is there a node to adjust the glancing angle of the reflection?

Thanks,
Fred

This is out of my field of expertise, however I recall it being discussed in these forums (potentially regarding the Quixel shader?). Suggest you search these forums for an answer.

Thanks Paul. I will see if I can find a solution.

Hi Paul,
I have tested scattering node, and it looks like it does not work, can you please check it. It has no effects.

I'm not sure what you mean by this. Can you provide a workflow or sample scene which demonstrate this problem pls?

Thanks

Ok Paul,
I will prepare a scene, to check it .

Cheers,

PS: Nice to meet you on linked in

I have refreshed the installers at the top of this thread with:

3.0.6.97
- Compiled with Octane 3 alpha 6 (3.0.6). Note the minimum Nvidia driver required is 353
- The Object Layer Color render layer/infochannel kernel type is not yet usable
- Changes to the Linux build to support earlier versions of Linux

3.0.4.97
- Fixed issue where the Baking Camera was sometimes missing Baking Group Id and UV Set

3.0.4.96
- The Object Layer node connected to an exported .abc file is now named according to it's owner .abc file when using the octane.saveAnimation command
- Color Correction->Brightness now has a maximum value of 100

Does Udims works with displacement node? I cant get to work here only diffuse udims. version 3.0.6

I doubt UDIM's would work with displacement, since the UDIM node graph does all sorts of transforms on the texturemaps, which is not going to work with the current Octane Displacement implementation.
