Hello world,

got a strange problem here. Rendering scenes assembled with many referenced files, cameras, shaders and such I experience an error with the Alpha channels of the rendered images. As long as some geometry is still in frame everything works out fine and the matte is predominantely black with only the object white. However, once there is absolutely NO geometry in frame (wich happens with multi-camera-rendering) the matte comes solid white, wrecking all my subsequent processes and calling for image-by-image fixing.

Is it the "straight" alpha I render ? Is it the references messing up ?

Thanks world, chris.scherer

Hi _david,


You may want first to delete any image plane in the scene.
Then verify the attributs of any cameras with select defaultRenderGlobals;
openAEWindow;

:)

No, sorry, no imagemaps here. But the error abates when rendering in Maya, yielding black image and black alpha. Only the batch-rendering seems to go haywire...
