Houdini not starting on Mac OS X 10.9.5 March 19, 2018, 10:41 a.m.

Is it only crashing when started from the terminal? Also, what are your system specs?

COP Metadata March 13, 2018, 8:42 p.m.

Metadata is like a detail attribute for COPs. As cpb mentions, it cannot be exported to file yet, nor can it be animated. The intention was to have it read in metadata and also export, but a change in development direction shelved that feature.

cbp: You'll want to use the copmetas() expression function (string), not the copmeta() (float). hscript functions can't return different types for the same function name, so they have different names.

Vulkan for osx
To beat twod to the punch, it doesn't have tesselation or geometry shaders, so it's a non-starter for now, unfortunately.

Yeah, we heavily use Geometry shaders for picking, wire-over-shaded modes, and handling vertex and primitive attributes. They're pretty indispensable to our renderer.

Vulkan itself is a non-trivial amount of work to switch over to as well, as shader introspection is not supported, which we rely on fairly heavily. Not to mention all the extra low-level things like VRAM and object lifetime management which we'd be responsible for, which the GL driver currently handles itself.
