Hi Lynx ,<div><br></div><div>The depth in the z-buffer represents the distance of the pixels to the camera. If you need to 'invert' it, you need to know the maximum depth you have in the scene and do:<div><br></div>
<div>newdepth = maxdepth - depth (easy to do with a few Convertor->Math nodes)</div><div><br></div><div>Technically speaking, the MaxDepth is the camera Clip End distance.</div><div><br></div><div>By the way, this is more of a Blender question than a Python one. As such it may be better fit in a forum such as BlenderArtists.org<br>

</div>Just found out how to do this for single objcets:<br>
Under Material disable! Transparency and choose "Invert Z Depth" under<br>
Options.<br>
<br>
But how can one achieve this for a whole scene in which objects overlap from<br>
the view of the camera?<br>
<div class="HOEnZb"><div class="h5"><br>
Thanks for any help or hints<br>
Lynx<br>
