OTOY Forums

Otoy® is proud to announce the availability of a new OctaneRender™ for Maya® Version 4
The world's fastest and most feature-rich unbiased render engine that integrates completely into Autodesk® Maya®.

Maya® Version Requirements

This release will work with Maya® Versions 2016, 2016.5, 2017 and 2018 64-bit on Windows, Linux and OSX operating systems.

License upgrade

Unless you have a subscription license, you will have to upgrade your version 3 licenses to version 4. This upgrade is free and can be done via these 4 steps:

1. Go to https://home.otoy.com/render/octane-render/purchase/
2. Select "Upgrade" in the top menu.
3. Click on "UPGRADE NOW" next to "Upgrade existing licenses to OctaneRender 4".
4. Select the licenses you want to upgrade and confirm.

To use this version, you need a GPU of compute model 3.0 or higher. Support for Fermi GPUs (like GTX 4xx and 5xx) has been dropped. Also make sure you use a driver of version 419.17 or higher and if you are working on Mac OS that have a CUDA driver installed that supports at least CUDA 9.1.

Changelog and the installers for Octane Standalone are here:
OctaneRender Standalone 4.05

Please read the new features implemented from Octane Standalone 4 version our blog post.


Changes since version 13.48:

• Fixed the settings' issue: the out-of-core size input fields were treated as bytes instead of megabytes.

Is it correct to asume that this plug-in doesn't have working Scattering nor Absorption mediums?

I've done some more testing. It seems that connecting Mediums to Diffuse shaders is broken... altering values on the Medium node doesn't even restart IPR.
However, using Mediums with a Glossy material (as shown in the youtube Octane for Maya videos) does work.

I understand that this is a older version but still supported?

Do anyone know how to get this OSL texture working with Octane:

OSL shader:

// Micro Scratched Texture

The osl texture works fine in standalone. It just causes issues in maya for some reason.

hi Blackshore,

Thanks for the post.

We are unable to reproduce this error.
Please find the file attached using the same OSL compiled using texture node.



cheers

Your shader works. Not sure on what you did.

I have added the OSL here if there is more wish to download it.

Thanks btw!

Hi Blackshore,

Thanks for letting us know it worked.
We copied the code and then compiled it.
