Welcome to TVPaint Community forums !

Is it possible to "render" what I see on the screen when I use the lighttable?
So I can see the drawings of the last few frames with a fade out effect.
I know how to "see" this in my project window but I want to render this as an effect. Or do I have to use a different effect for this ?

Agreed.

If this isn't possible, I think this should be a feature request--sometimes I have an interesting light-table setup that I'd like to share as a render, and wish there were a "render light table" FX option. Those fading blue trails can look cool!

i know what you guys mean,
the LT can sometimes get you a real nice effect 'for free'
i once requested a 'Lightable FX' back on the bauhausforum.
it probably has low priority because you can already simulate it by simply duplicating layers and offset them.

an idea for a solution was to maybe have an save LT option in the exportwindow (see image)

nice! I would love that too. Light table images manifest the power of accident. that's what experimentation is all about. and this is where TVPaint is stronger than any other software.

You can use this method (only if you need a single image) :
* Enable the lighttable
* Click on the title bar of the project window with the left mouse button + hit the [g] key.

You will have the current project window as custombrush.

and then you can do the same for each one of the frames in your animation ...
we should work hard for good results, just like the old masters did!

I think, this is be the best way then

You can build this with a stack full of Source image FX.
Set increasing/decreasing values for offset and a Opacity.
Chose Display as source.
Apply the stack on the full sequence.

off course! ...very clever Manuel
this way you can save the FX and apply it to any project with a few mouse clicks

if anyone actually wants to build such a stack... please share in content sharing

excellent idea !

i couldn't help trying this and it works great
but how to color the lines like the Lighttable does?

'replace color' effect doesn't affect blacklines.
nor those color adjust, Hue angle only works if there is already some Hue there.

so the question is: is there an effect in the stack that can turn black pixels into any color?
most logic to me would be 'color replace' but it doesn't work

try : stylize -> color range
and select a plain color for the "gradient"

me again...
I created an fx stack with 4 "image source" effects in one row.
Before applying the fx stack everything looks exactly the way I wanted it.
But then it just adds more and more lines to the previous frames (see picture). What am I doing wrong?

The values for opacity are too high.
You would obtain a better result if using 5, 10, 15 and 20% instead of 25, 50 and 75%.
This is due because each new frame take the previous one as a reference and opacity are added so that you obtain something like you had in your example.

but would not the solution then be to apply it to a new empty layer?
instead of adding to the existing one.
