How to deal with bounds errors when rendering with Arnold

When importing a character in Golaem and saving it to a .gcha file, Golaem automatically compute a bounding box for your character.

In some cases, i.e. extreme animation, physics simulation, cloth simulation.... the geometry of your character can be bigger than this bounding box, and Arnold will complain (actually in version prior to Arnold 1.4.2.1, it crashes because of an Arnold related bug).

To fix this (waiting for Arnold 5 compatibility, which will remove all needs for providing bounding boxes), open your .gcha file in the Character Maker, go to the geometry tab, click on the Character Node, and increase the bounding box size.

Do not forget to save your .gcha file and try again.
