@Alan - Adding transparent images

I'm trying to add animated gifs to Maya. I've started by just adding one still .tiff file to check it looks ok before tackling the gifs, but it's not working properly. I want it to look like the top image, so transparent, but when I render it is still showing the plane. What am I doing wrong? 




In Photoshop I've tried using the same process as when I create the eyes and phonemes for the facial rigging to see if this worked but apart from changing the background of the rendered plane from black to white, it still doesn't seem to have worked.

  1. Hey Emma :) hmm, this may or may not work, but try deleting the Alpha channel in the picture.

  2. GIF's don't work in Maya Emma. You need to create an image sequence (tiff's) and then cycle it. Secondly, if you're using Arnold, the transparency doesn't work until you select the geometry and go to the Arnold section (Attribute Editor) and turn off 'opaque'. To create a cycling animated sequence:

    1) Create an file node in the colour channel of a shader (lambert).
    2) On the file node click 'use image sequence'.
    3) Right click in the 'purple' image number channel and choose 'delete expression'.
    4) Now set a keyframe in the image number channel (right click/set key) on frame 1
    5) Repeat for the last image in your sequence - eg frame 10
    6) Select the file node by copying the name - eg file1 - and going to the dialogue box at the top of the screen / just under 'workspace'. Make sure its set to 'select by name', enter the name, and press enter. You can also select the file node using the Hypershade.
    7) In the Graph Editor select the animation curve and make it linear and then cycle it.
