Maxwell Render | Official public forum

Hi guys,

I am trying to use the parameter Post-Render Script in the MAxwell ROP, under the scripts tab but I either get a crash or no result.

This is the line I am using for this parameter:

unix ce_maxwell_submit.py -s 30 -e 31 /prod/projects/mcdonalds_lcm_bundles_mar14_20140/shots/s010/ifd/test_render_v01_t02/s010_test_render_v01_t02.0012.mxs

Note that the same line above works on houdini textport but doesn't work on the maxwell ROP. It is the same syntax that I usually use for a mantra but using a different python script.

If I turn on Export MXS files (no render) under general Settings, and click render. The parameter Post_Render Script seems to be complete ignored because the script doesn't get run and I don't get anything on my terminal.

Does any one have an experience with this that could help me out?

Thank you very much for your attention

Rodrigo Guimaraes

The log below is when I get the crash.

Hi Rodrigo,

I will take a look and fix this in the next days if I can reproduce.

Peter

The issues is fixed, will be available in the next release, within some days.

A new build (v3.0.0.2) is released with the fix. Also pre and post export scripts can be defined now.
