I’ve successfully done single inserts, but how do you do multiples. Do you have to render one layer at a time.
As long as the cog for each layer is on, you can render them all at once.
If you need to have each inserts as separate rendered sequences, then you will have to turn the individual cogs on and render for each. Make sure you create a new output clip for each separate render however, as by default they render to the same clip.You can set a new output clip in the Output tab in insert.
