Render view way faster(30x) than render to disk when timeline seeking after first render on trivial animation. Nov. 9, 2018, 8:48 a.m.

Paolo Oliverio
On windows, I once found that I could speed up the render startup significantly when running as admin.
thanks, I have tested it and I get 18 sec in Mplay with both standard and admin.

A 17 second start up time is outrageous and shouldn't be happening.
a) When you turn on verbosity in the render, what does the timing report?
b) Do you get the same behaviour if you render directly to disk files (i.e. render from the ROP)?
c) How long does it take for Houdini itself to start up?
d) What happens if you set the engine mode on mantra to “none”?

To me, this almost sounds like there's some kind of timeout happening, possibly with license checks? Or maybe loading a lot of different plugins?

This post ( from a long time ago seems that they solved the problem with a DNS lookup issue.

Compiling the Pixar USD Houdini plugin on Windows Nov. 5, 2018, 7:41 a.m.

I'm not sure if this is relevant, but there is now a project in the HDK samples to build the USD plugins which should work on all platforms (see $HFS/toolkit/usd_houdini_plugins).

The source provided there should match the same git version as the libraries shipped with Houdini.

I don't think it helps if you don't have a compiler environment though.

padzero in vex? May 2, 2018, 7:40 a.m.

This might be a little easier
padzero(int n; int v)
    return sprintf("%*0d", n, v);

    printf("%s\n", padzero(5, 126));
    printf("%s\n", padzero(5, 23));
    printf("%s\n", padzero(1, 23));
