OTOY Forums

Hi all,
This is the latest stable plugin build based on 2021.1.3 SDK. Any feedback will be much appreciated. Enjoy it!
This is the SDK matching Standalone 2021.1.3.

Make sure to use a NVIDIA Studio driver with version at least 456.38 on Windows. No driver updates are required for macOS 10.13 (CUDA).
This version supports the new NVIDIA Ampere architecture on Windows and Linux. Kepler cards with compute model lower than 3.5 are just supported on macOS.

Changes of 2021.1.3 plugin
- Added new transmission type "Thin wall (diffuse)" to the universal material. It is meant to be used for thin surfaces like leafs and treats layers of the universal material to be independent of the side of the surfase. I.e. an incoming ray will always enter the topmost layer first.

Core changes since OctaneRender 2021.1.2:

• Added new transmission type "Thin wall (diffuse)" to the universal material. It is meant to be used for thin surfaces like leafs and treats layers of the universal material to be independent of the side of the surfase. I.e. an incoming ray will always enter the topmost layer first.
• Performance optimizations for devices of all supported compute models with the exception of 8.0.
• Fixed saving of AOVs that was ignoring non-cryptomatte AOVs after the export of a cryptomatte AOV.
• Fixed the power input of a texture used as a normal map being evaluated as a normal map (see viewtopic.php?p=409683#p409683).
• Fixed unnecessary geometry rebuilds when switching between universal camera nodes, if you use vertex displacement and the vertex displacement texture has inputs outside the root of the texture node tree (see viewtopic.php?p=409585#p409585).
• Fixed application crash when using meshes with animated joints and shutter interval set to 0%.
• Fixed incorrect camera parameters of the first frame in certain situations when you do a batch render.
• Fixed a crash when you delete a volumetric light that is connected to a render target and rendering has already started.
• Fixed motion blur in scenes loaded from USD.
• OSL: Fixed crash when using certain struct constructors in OSL.
• OSL: sqrt(x) returns 0 for x < 0, as specified by OSL.
• OSL: If a geometry input on a Vectron node is not connected, the _sdf struct gets the material ID of this node by default.

IN ANY CRASH CASE PLEASE DO THESE!!!
If you see CUDA errors follow 1,2,3,4.
1- Use NVIDIA STUDIO drivers, not Game Ready versions. If you have stability issues try different drivers, some of them could cause instability issues. Make a clean install while doing this to be sure previous files completely removed.
2- Check GPU frequency. Overclocking would cause instability issues
3- Check PSU. Insufficient power output would cause instability issues
4- Check the free amount of GPU's VRAM and system's RAM while working. Low VRAM will/may cause CUDA errors. Be aware of some generator objects will have different triangle count in Picture Viewer than Live Viewer. It’s like “editor/render” parameter. Just try to use the same value. Also try to optimize your scene for polygon count, even use smaller images. Try to use Octane texture nodes rather than using C4D texture/shaders.
Alternatively, use V4 and Out-of-core(OOC) function. Increase RAM for OOC and It should not exceed physical RAM amount. Check TDR value and increase if it's necessary.
5- If you see C4D crashes without CUDA errors, then send us bugreport.zip, screen-shots and video capture to show process and crash moment. Also please send us a sample scene in a format of C4D or ORBX to let us investigate and test it. Alternatively, try to delete/hide some objects/materials until crash gone away. If you find what's causing crashes, send us a sample scene to let us for investigating and bring a fix or solution.
Thanks for helping the development by your feedbacks! It’s impossible to quickly catch every case without user feedbacks! It’s the same procedure as other companies do like Maxon/etc...

Requirements:
-You'll need to update your Cinema 4D to latest versions(R16.050, R17.053, R18.057, R19.053, R20.057, R21.115, S22.118, R23.110, R24.111, R25.117). Otherwise, the plugin will not work and not appear in menus.
-Internet connection for activation, be sure that C4D and Octane will not be blocked by the firewall and any antivirus software.
-Nvidia drivers at least Nvidia Studio Drivers(minimum 456.38) and be careful with latest Game Ready drivers which can cause cuda errors. Stay with stable one for you.


ONLINE HELP MANUAL
Use embedded help buttons from Octane nodes and windows
or from link: https://docs.otoy.com/cinema4d/OctaneRe ... ema4D.html


Installation
First, remove all octane related stuff from plugins and the main folder of Cinema4D.

Extract all files to Cinema4D\plugins\c4dOctane directory.
Also, download manual.zip and extract to c4dOctane directory if it's not available in place.

There are a few files for each one is for different Cinema4D version. Remove all except the file is for your version.
Ex. if you have Cinema4D R18.0, keep only "c4dOctane-r18.cdl64" and delete c4dOctane-r17.cdl64, c4dOctane-r16.cdl64, c4dOctane-r15.cdl64, etc..

Thank you, Aoktar!
Testing later today.

Report a problem.
After version 2021.1.1-R3, Octane Scatter objects in surface Type can't be scaled or resized.

I noticed problem when many image nodes are connected to gradient for example. There is huge C4D interface freeze ( 8-12 seconds ) after make simple changes in nodes - even moving them. During making changes there is no delay but after mouse button is pressed out this huge delay occur after 1-2 seconds. Probably because Octane plugin do some caching of nodes after changes. If there are many textures especially huge EXR ones this is very visible. I have disabled node previews, OGL previews from Octane and any other such things. Probably unecessary caching when previews are disabled.

When object invisible to camera is behind LV camera, selecting materials by cntr+LMB doesn't work - it always pick this invisible object material - is there way to avoid this ?
