Hi Jordan,<div>this is such a non-cycles question that I think you will have a better luck going to the blender forums</div><div>(e.g. <a href="http://www.blenderartists.org/forum">www.blenderartists.org/forum</a>) for more in python, the api, ...</div>
<div><br></div><div>Anyways, this is what I use to get a render that takes only half the width:</div><div><br></div><div>setRenderBorder(bpy.context.scene, 0, 0.5, 0, 1.0)</div><div><div><br></div><div>def setRenderBorder(scene, min_x, max_x, min_y, max_y):</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>""""""</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>render = scene.render</div><div><br></div><div>
<span class="Apple-tab-span" style="white-space:pre"> </span>render.use_border = True</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>render.use_crop_to_border = True</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span># set border<span class="Apple-tab-span" style="white-space:pre"> </span></div>

Ok I guess that makes sense. But looking at a page like this:<br>
<a href="http://www.blender.org/documentation/blender_python_api_2_63_12/bpy.types.RenderSettings.html" target="_blank">http://www.blender.org/documentation/blender_python_api_2_63_12/bpy.types.RenderSettings.html</a><br>
<br>
How could you find how those variables can be called (by the various variables you specified)?<br>
<br>
Is there a way to figure out the complete list?<br>
<br>
It is very confusing for a n00b.<br>
<br>
thank you,<br>
jordan<br>
