Does anyone know how to render alpha chanel and roto in mantra? I setup in /output/Mantra/Deep Raster and try to get alpha images. And set VEX Variable to Af . However, all taga images turn black. there is nothing displayed. I don't know what I do wrong. Anyhelp I would be much appreciated.
Where you have VEX Variable set to Af in the Deep Raster tab in the parameters, stick in an appropriate filename right underneath (instead of Af) for the File/Plane Name parameter.
