I'm trying to render a series of files like so:

for i in range(1,17) :
s = “shot_%d_v1.hipnc” % (i)
print “attemping to load ” + s
hou.hipFile.load(s)
mantra = hou.node(“/out/opengl1”)
mantra.render(verbose=True)

After it finishes the first file it crashes. I've run into a similar thing with hscript. Is this not possible?

Hscript example
for i = 1 to 16
mread shot_`$i`_v1.hipnc
render -V /out/opengl1
end

I found examples on the forum that suggested you could do:

mread shot_1_v1.hipnc
render -V /out/opengl1

mread shot_2_v1.hipnc
render -V /out/opengl1

and so so on. Those also crash.

The code looks fine. It should be possible to render different .hipnc files in the same hython session.

If you can reproduce the crash consistently then I suggest submitting a bug report to SideFX support. Be sure to include a test .hip file and/or python script as well as the crash log.

Cheers,
Rob
