Transform multiple layers at once

schwarzgrau · Post by **schwarzgrau** » 22 Feb 2016, 12:41

I know there is at least one thread on this topic, but I could't find it.

I guess this isn't easy to realize, cause if it would be, I guess it would be already in TVPaint. But it would be soooo helpful, if you could PAN and TRANSFORM multiple layers at once, especially if the head is on layer 1, the body on layer 2 and the arm on layer 3.

This is already the case in TVPaint 11 with Transform tool, if you have selected instances and if you have change the mode for "all layers" or "layer groups".

Wow, this was fast

Thank you for pointing this out to me!

At your service !

I noticed that you can select multiple layers, transform one and it gets applied to all other selected layers. This is surely faster then transform one and apply the transform to all other layers, but the bigger problem is, that you can't see how the layers transform before you apply it.

Just like the FX stack... sadly, we cannot display the change on several layers in once

I have absolutely no idea of software developing, so it's probably rubbish, but wouldn't it be possible to internally merge those layers to show the transform, while doing it and then apply it on the original layers, as its done now?

not as easy as it seems.

TODO listed for a long time anyway.

Shortly after posting this idea I thought "if it would be that easy, your probably had already done it." But nice to know it's already something on the list.

digging into the deep past (2009 I think) is this tvpaint 9.5 button script that lets you merge all layers to a new, top layer (leaving all existing layers intact). Note that the new, merged layer is automatically turned off when it is created...

Perhaps this could be adapted to preview a multi-layer transform, then simply be applied to all the individual layers at once?

I did a quick test and it worked for me.

Hmmm ... I will try to explain it well :
In fact, there are plenty of options in the software when the preview is on the current layer only.
So if we change this (and we will sooner or later), it has to be done correctly in the code, I mean : at the right place, so probably deep.
Your suggestion might work, but that wouldn't be a "clean code" ... so it would work for a few months maybe, but once someone will need more options in the tool or an other change, you might get bugs or worse : the impossibility to evolve later without rewritting everything. That what we try to avoid as much as we can.

Fabrice,

you misunderstand. I was just making this suggestion to schwarzgrau as a temporary George script solution to his desire to preview multi-layer transforms, not as a serious solution for the programmers.

I know fully well how "quick patches to code" (that are not deeply thought out and tested) can come back to bite you.

sorry.

Thank you Sven. Unfortunately it merges all the layers, not only the selected.
