Maya for 3D Printing - Rapid Prototyping

In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

Issue: Arnold Batch Render with Alpha Channel

When batch rendering with Arnold Render(1.1.0.3) in Maya 2015 (Windows 7), I get an alpha channel rendering a single frame. When batch rendering an entire animation i do not get the alpha channel in the images to composite. Any help would be appreciated.

Initially I used .png, it didnt worked. Then I tried .tiff and that still did not work.

single frame renders alpha well, but when batch rendering, it shows black background

tif seems to work fine also. There is something wrong with the png´s alpha. Even with standard materials matte it doesnt work.
