How do i? Transparency Effect

[Peter Wassink]

I took the liberty to move this Question From Facebook.

To the attention of Peter. We wanted to ask you if you have time to think about how to solve a technical problem. We have this particular look in a short movie that we’re producing right now, in TVPaint. Attached you can find a style frame of our movie, we want to work on frame by frame 2D animation, with the character of the woman that is dark, but with transparency on her skirt and on her sleeves. You know if there’s some kind of trick to obtain that in TVPaint fro every frame? If you have time to look at it, would be great! Thank you very much!

Hi Michele,
you need to work in multiple layers.
and to use masks which would allows you to control the animation of gradients.
so you'd still apply gradients by hand, with the airbrush tool but only after you finished the line animation and you make seperate passes through your scene, for each detail, isolating it with masks. to minimize jerkiness.
so you'd first shade all the frames of the left sleeve , then all the frames of the colar etc.etc. preferably adding a new layer for each part, that way you keep control over how it mooves.

i'd do something like this:
first create a layer for the body, then a layer for the clothing. Then using paintbucket(floodfill) color (black) each of those.
then you make a duplicate of the clothes layer. And here you apply the Toon shading effect, (set the spread at 360, intensity around 100%and size at 70pix, but play around with these) This effect will give you a nice base to start from.
then you switch on the stencils (last colomn in the layerpanel) on both the body and the clothing layers and on a new layer you can then add detailed shadows like for instance the sleeve colar using the airbrush tool at say 50%power. the stencil will only let you apply on the shapes.
for the highlight do the same on a new layer using a lighter color or set the blendmode of the layer to light.

good luck!..there are more ways of doing it though i'm sure my suggestion will bring up more questions.
But for that i suggest you take this to the TVPaint forum, where also others can add advice or have even better suggestions and where its easier to share stuff like examples brushes...etc
see you there
