will the free version of houdini render all 240 frames.
I tried,but got only 1 frame.
please help.thanks

Yes, it should be possible.

Make sure the “Valid Frame Range” is set appropriately.

There's no reason why it should not work. I take it your render file looks something like $HIP../../images/myrender.$F4.pic and you have set the correct valid frame range ? . If your still stuck post up your scene file

There is a bug that renders only one frame when you invoke the render node from the main menu (Render > Start Render > mantra). But if you press the “Render” button in the parameter pane (Render > Edit Render Node > mantra) for that node, it will render all the frame range specified under the “Redner” button.
