So I'm fairly new to Houdini and am starting to get the hang of it, but every now and then my operators error and I'm not too sure why. I would like to get more information on them and why the data or operation fails to work. I know about middle mousing on the operator and it's inputs but sometimes the error isn't particularly helpful.

Currently I'm stuck as my import water source, from a DOPnet, going to a ‘particle fluid surface’ operator is not outputting a surface polygon soup correctly. The error reports “Invalid source particlefluidsurface1:copy_sim_detail_attributes…”

That's fairly hard to comprehend, especially as I guess I'm not receiving the whole error by the fact that it ends with, “…”, ellipses… Especially as this network came from the shelve.

So:

A) How do I print the whole error to try to debug it myself?

B) How do people normally go about debugging their scene?

Thanks,

Hi,

I'm trying to render some motion vectors from a Pyro fluid to use to blend between sprite frames for game FX. The technique I'm trying to work with is described here: http://www.klemenlozar.com/frame-blending-with-motion-vectors/ [klemenlozar.com]

I want something like this:

I've created a Pyro sim and have tried rendering out motion vectors using the RSMB_MV shader applied to my Pyro. This just renders out a blank colour, with no vector information applied.

I'm pretty new to Houdini and I don't know if this is the right technique, or is there another way?
