Hi is there an easy way to use UDIMs with Octane in Houdini?

This feature is not supported yet by Octane, but it is a planned feature. I know that other plugins have some hacks to support UDIMs, but the Houdini plugin doesn't have one yet. Anyway, I hope to see this feature natively supported by Octane soon ;)

Thanks,

It's something we wanted to be sure we needed to do in the core (v.s plug-in layer) before we went ahead with it ourselves (BTW this feedback is great!). Since it is looking like this may end up being the best way to support this feature robustly, we'll review where it might best fit in with the rest of the 3.x roadmap.

The tricks implemented in the plugins to support UDIMs rely on transforming the UV coords of the Image nodes - and this approach does not work with Normal and Displacement maps - so core engine support for UDIMs would be great.

Yes, I also think that a robust support for UDIMs in the core without tricks in the plugins side, and will full support for normal and displacement maps, could be great. Anyway if finally this feature is delayed I could think about adding the transforming UVs hack to the Houdini plugin.

I assumed as much. I got around it by creating a unique material per UDIM since I am using displacement. Worked great!
