@SSmolak, adding the Diffuse Indirect to the Main Beauty pass is working properly, though you have an error in your AOV tree. I am including a corrected version of your file to assist you.
To make this work properly, you need to adjust your Wall material and your AOV flowgraph. The corrected Wall material makes use of the
Capture (to Custom Texture) AOV, inserted between the
Triplanar node and the Diffuse on the Wall material. It is set to
Custom AOV 4, as illustrated below:
In the AOV flowgraph, you need to create a
Custom AOV. To do this, go to
Render Settings > Octane Renderer > Render AOV Group tab > Render AOVs turndown and click on
Add Render AOV > Custom > Custom AOV and set the
ID to
Custom 4 (in this example) and set
Visible After: to
None-Primary Rays Only.
Next, go to
Render Settings > Octane Renderer > AOV Groups tab and add an input, which will create a
Composite AOV Output Layer node connected to a Composite AOV Output node, which is then connected to the
Composite AOV(number) input pin on the
Octane Renderer node, as illustrated below:
Make sure you have two input pins on the
Composite AOV Output node (select the node and choose
Add Layer if needed.) Now, connect your
Diffuse Indirect node to the
Input pin of the
Composite AOV Output node, making sure that the
Blend Mode is set to
Add and the
Alpha Operation is set to
Blend Mode. Then, Create a
Render AOV Output node and choose
Custom AOV 4 as the
input, and the
Output channels to
RGB. This section should be connected to the Layer 2 input pin of the
Composite AOV Output node.
Connect the
Beauty AOV node to
Layer 1 of the
Composite AOV Output node, and make sure its
Blend Mode is set to
Normal, and the
Alpha Operation is also set to
Blend Mode. I have added an additional
Composite AOV Output Layer node in between that connection, but it does not seem to be necessary for the bottom layer of this composite (which is what we have built).
This result is now viewable via the Out1 button in the
Live Viewer. When comparing
Main to
Out1, you will clearly see that
Out1 is brighter, due to the Add operation. Therefore, you can properly add a Diffuse Indirect on top of a Beauty (or anything else).
The only thing I have not been able to do is to isolate the bottom faces at this point. Currently discussing that point with the dev team.
We will be releasing a documentation update next week that contains detailed AOV information, and updates all around, focusing on the 2021 series.
