Display objects at specific times

[lxclxd]

I want an object to be displayed in 12 seconds and not seen before 12 seconds.
How can I do that?

Forgive me for not speaking English well

Hi and welcome among us
You can use the “Amount” parameter for such purpose

How to make BLine appear in specific keyframes ONLY

BLines (now called Splines), like any other layer can change its visibility by the ‘Amount’ parameter. Making it zero (full transparent) will make it disappear and changing it to 1.0 will make it appear again. Any value between 0.0 and 1.0 will make it partially transparent visible. You can use ‘Constant’ interpolation to quickly change between one value to other without transition (which maybe is what you’re looking for). -G
