"Octane: generate material" being slow

[[email protected]]

Hi

I'm getting a lot of beachballing slow-downs because octane is constantly generating materials over and over again.

Even when I'm not rendering it does this, showing it in the process bar (image attached)

Why is it doing this? And is there a way to stop it or speed it up?

Thanks!

It's a process from material preview generations. What do you have so much expensive in your materials?

I have a few complex material node networks. Some are using a few 8K image textures.

Is there a way to disable these previews?

There are some option may help a bit. Better to disable octane for opengl. Also note that previews will work faster when you have scene sent to Live Viewer

This does the trick, although now it doesn't texture in viewport. But i can live with that. Rather have speed if I have to choose.

Thanks!

You can enable when you need. Also tif/etc.. are faster than PNGs. Additionally using c4d shaders are making slower that.
On latest version we have cpu preview rendering for some octane types and can be faster.

Ok thanks for the advice.

I've been using Jpegs to keep the size and load-time low.

Would TIFFs be better for octane than jpegs in this respect?
