Point Attribute Limit?

[mgtaylor]

Hello,

I've created multiple point float attributes using the mask paint sop and fed them to Octane. After about 5 or 6 Octane seems to suddenly disable a random one or two. But once I'm back down to 4, it seems to feed all of them to the shader fine.

Sorry, I'm afraid that currently Octane only supports four float attributes and two vector (color) attributes at the same time. Perhaps you could use the vector attributes to store floats in your workflow if you are not using them yet.

Thanks,

That's good to know. Thanks very much for the reply!

Hello Juanjo,

this sounds as if it would be possible to extract the single float values from the vector inside of the shader network. How can you do that?
Or did I missinterpret your message?

In Octane 2021.1 you can use the channel pick node, or you could probably build a simple OSL node with this feature.
