How do you get rid of/simplify VEX include? Aug. 8, 2019, 11:13 a.m.

Batch renders with Arnold using PDG July 27, 2019, 9:40 a.m.

Houdini is backwards compatible and still supports SHOPs in older setups. So if you still have the Arnold's Standard Surface Shader SHOP, it should work fine.

Ultimately, it's up to the Arnold's ROP to interpret the shader networks (be it SHOPs or VOPs) and translate it to a format consumable by Arnold renderer. It may be worthwhile to ask on Arnold's forum about it.
