I am getting some VEX errors on shaders when I open files from Houdini 12.1

Any ideas?

Thanks.

I forgot to mention that I get those errors when I render the file, did anyone else had this kind of problem?

You probably have old VOPs embedded in the .hip files that are overriding the ones used by H12.5. Look in the operator type manager under Embedded and see if you have a “Surface Model” or “Physical SSS” and other related shading VOPs and remove them, then try rendering again.

That's it!

Thanks!

Is there a way to delete or remove all embed otls at once?



I figured it out, there's an option to uninstall all of them

Cheers!

what if I get that error after getting a new build version. and I don't have any embedded otls in the hip file?
I am reading my otl from my scanned paths
:?

i also started a new scene, and drop my otl and got the error .
