You are right. I am moving from C4d to Houdini and forgot that Houdini doesn't create UV by default on objects like in C4D.
Anyway, I was afraid, that switching from C4D to Houdini Octane is hard. But no, I like Houdini version even more, And surprise - All my Local DB materials from C4D is 90% working in Houdini also. So, waiting for 2020 which must be even better.
But still one question is not clear. Many users and in many videos I saw that Octane Houdini has one problem - it doesn't support Point Attributes. But I see that 2019 version has Color Vertex Attribute Node, which is not described in documentation but it allows to get Point attributes. So, it's available in 2019 version?
