Hi, its been a few day I cant get rid of this artifacts on my object. I tried everything, cleaned attributes and groups by Clean SOP, Polydoctor, then i tried Divide it using Divide SOP, and then ive been told about Ray epsilon, and still nothing, its shows everytime, i was trying to delete some parts of the object to find which one is broken, and its shows really weird, it didnt help. But in octane standalone it works fine actually, this bug only in Houdini, (i have 17.5.173), it broke my head, such kind of magic
here is the model so you could try it
