Ok, long time no post, so here it is: I haven't posted this python script, that is already on creativecrash: glt_reloadrange. Basicly it checks the frame range of the selected readnode, and if it is different that was set in the node, updates it. It useful for example when you start using a 3d rendered sequence, before it is fully rendered. After the 3d render has finished, just select that readnode, and use this script.
