Hi!
Maybe a beginners question but where do the houdini engine in maya get $FSTART and $FEND values from? They seem to be stuck at houdinis default values (1 and 240).
We start our shots at frame 1001 at our company, and this has caused some issues with some nodes. For example the trail sop has an option to “Evaluate Within Frame Range”. We need to uncheck it to make it work as expected.
Cheers!

Is it possible to get the distance the current ray has travelled?
I'm looking into doing something similar to this:

where they have a nice way of simulating multiple scattering in volumes by varying some parameters along the shadow ray.

I'm trying to submit a houdini engine job to our farm and trying to figure out the best way to do it.
One step in our asset is to mesh a particle simulation to an alembic file sequence. We would like to distribute this on our farm. I've managed to do it locally by the following mel command:
setAttr Sop_mesh_asset_test.houdiniAssetParm.houdiniAssetParm_execute__button 1;
Where “execute” is the name of the button excecuting the rop output driver.
When we do it in batch mode maya doesn't wait for the houdini engine to finnish and exits right after the mel command. Is there another way of doing this?
One solution would of course be to save the underlying houdini scene and execute it as we do with our normal houdini jobs.
Cheers,
Simon
