Houdini 17.5.242 There was a bug in the VEX compiler when dealing with arrays of structs as member data in other structs. When the array had no initializer specified, the compiler could end up throwing a cryptic error message. Mon. April 29, 2019
Houdini 17.5.242 There was a bug in the VEX compiler when structs were declared that referenced arrays of other structs. The issue was that the compiler could fail depending on the order of the declaration of the structs. The compiler is much more robust and arrays of structs as member data should work more consistently now. Mon. April 29, 2019
Houdini 17.5.242 Unset LD_LIBRARY_PATH by default when autostarting HARS to avoid some library conflicts. There is a preference that can be unset if you need to be able to start the server with a specific LD_LIBRARY_PATH Mon. April 29, 2019

Thu. April 25, 2019
Houdini 17.5.238 The Hair Clump SOP will always duplicate the input detail for now, rather than manipulate it in place. This avoids a bug where output attributes could overwrite input attributes of the same name before they are read. This could easily happen with the tightness attribute.

The intention is to revert back to in-place cooking in a future update, along with checks for the conflict described above.

Thu. April 25, 2019
