TOPs ROP Geometry Output performance for caching Nov. 17, 2019, 7:52 p.m.

For simply caching out your sims is there any performance advantage in using a TOPs ROP geometry Output node vs simply a File Cache or ROP Output in SOPs?

re sim on Flipbook Nov. 17, 2019, 7:14 p.m.

Confused why unless I select my Pyro Import node when creating a Flipbook, I always end up re simulating. My display flags remain the same.

Inside my Pyro Import node I have a File node with a relative reference to my ROP geometry Output path inside my TOP network.

AFAIK, ‘correct’ behaviour is to simply load the cached files when I create a Flipbook, and not to re sim.

The only difference in the attached is that in one I have the TOP network node selected, while on the other the Pyro Import node is.

Anyone know why this is happening?

TOPs environment variables __PDG_DIR__ instead of ${PDG_DIR} Nov. 17, 2019, 5:10 p.m.

Noob question

In the sesi documentation it suggests to use __PDG_DIR__ instead of ${PDG_DIR} for filename paths.

ok, I tried and only received errors in the graph when cooking ROP Geo Output.
No issues if I use $JOB or $HIP instead.

That's the first issue

2nd is a noob question on proper use of environment variables in TOPs

What is the difference between

${PDG_DIR}

$PDG_DIR/

and

__PDG_DIR__ ?
