Matisse used some really varying styles in his work. For example "Madeleine I"
is very toon-shaderish (with a strong horizontal silhouette), while "Nude in
the Studio" is, I guess, what I'd call painterly (which is a dumb word because
it's all paint). I'm not all that knowledgeable about his work (I'm just
breaking it down from http://www.canvasreplicas.com/MatisseGallery.htm). But I
think the following is an example that might get you in the direction you want
to go:
Break your rendering up into as many passes as there are stroke styles in the
painting. For example:
+ Base pass: Render everything as a toon shader, with the basic color palette
and blending you want to use.
+ Silhouette pass: You could use this to leverage that varying horizontal
silhouette
+ Hi pass: Render only highlights and rim lights
For each of the above passes (especially the ones that are more painterly),
create a pass that just has a particle emitter in front of the camera, the same
size as the rendered frames. Assign the respective pass as the emission color,
size, etc. and get a good "dab of paint" look. Use ClipFX to tweak the source
texture correctly.
Then render out these three particle passes and comp together, applying your
favorite 2D "paint effect" to each layer (the FX compositor has a bunch of
these) and maybe doing a fake emboss shadow to get some relief. This way, you
're creating the large scale effects using controllable particles and the small
scale effects in 2D.
Do a final color correction to maximize the saturation after all of this.. I
mean, god, Matisse is making my eyes burn, and that's a good thing.

But what is it you actually want to make look like an oil paintiing? Do you
want to actually reproduce some oil paint being painted, or an image looking
like an oil painting? Maybe 'painterly effects' in the FX tree are all you need
?

the reference is that it should look like a Matisse painting.
I saw a making of Lorenzo, they scanned some strokes from the director and use
them as paint effects brushes on Maya, deformed by curves they draw based on
the 2d animations.... that was cool...
but not doable on XSI at least in that way. So im looking a way to achive an
oil painting look from the 3D.
