Very easy, if you for example want to use an imagetexture which has Alpha for color but also utilize its alpha channel at the same time, do this:

Just use an Extract4 (MX) node and set it to ID = 3 (0 = R, 1 = G, 2 = B, 3 = A)

Thank you for the update.

Added output type to Image Texture and OSL Texture nodes
Could you please explain what this update actually means and how it should be applied?

About OpenPBR....
1. When applying an OpenPBR material, the Texture Tag's Projection is changed to Spherical instead of UVW.
2. In the Material Editor, the Assignment section is positioned at the top.
3. In the Node Editor, the Open Node Editor button appears duplicated. It would be better to ...

I asked this question a long time ago but never received an answer.
If the Octane for C4D developer happens to see this, I’d really appreciate a reply.
Thank you.

Sorry, the image did not load the first time, now I see what you mean.

This error can throw memory management a bit out of whack and cause errors like the one you see in situations of low memory constraints, which used also to happen in older versions of Octane. I am not sure why this is only ...

Rendering the sequence through the Picture Viewer.
It seems that NVLINK is not working.
This scene occupies 30GB of VRAM, but only the first frame is rendered, and then it stops without progressing.
It seems to work properly only in the Live Viewer.

I tested the Nvidia Studio Driver version 576.02 and several earlier versions.
The Daemon (with NVLINK enabled) works only when the scene fits within a single GPU’s VRAM (about 20GB in this case).
I expected the Daemon to handle scenes larger than 20GB using NVLINK, but when the scene exceeds that ...

Is there anyone who knows how to get NVLINK working with the Octane Render Node Daemon?
It(Nvlink Peers) works fine in Standalone and in Cinema 4D, but the Node Daemon does not recognize it.
Is there an additional option that needs to be added to the batch file?
