Silhouette is only importing media as numbered sequences, which is fine for a high-end compositing software.
But usually you’d point to the first frame and it should import the whole sequence if it’s sequentially numbered.
That’s what is also shown in the tutorials by Ben Brownlee at Curious Turtle for Silhouette FX 6.
If I do this in Silhouette 2020 for a sequence, which is correctly numbered in single steps, only the first frame is imported as a still!
I took me a lot of fiddling with file names to no avail, until I found out accidentally that you need to activate all frames and then import to get a sequence.
This looks like a bug to me.
To avoid question about wrong, naming my names look like this: Stage.00086400.exr and so on in single frame increments. Anybody else seeing this?
