The last week, my machine was rendered and I was going to combine the scene with the machine through NUKE.

Since the two images that merge together will overlap, the first thing I have to do is make a projection to ROTO the part that is obscured in front of me. let the machine be behind the scene.

The ROTO must be done very carefully. Because it will affect your visual effect.

Once the ROTO is complete you can create a card to project the ROTO part onto this plane. This way the other camera can see the projected part when it is played. After that, the ROTO part Invert to the position of the Lieutenant-General to make an alpha layer. And combine this layer with the scene.

Finally, the machine will be toned and Merge to the scene with the production, in Merge a background to the machine. The entire video machine part has been completed

Afterward, to make the scene look more realistic, I removed the coordinate points on the teacher’s environment by projection.

Finally, I output the video, and my machine is finished.
