hello. i've been perusing the internet trying to find a solution without luck, so i'd like to post my problem here. i've been trying to achieve a particular (admittedly, unusual) effect and so far have been somewhat dissapointed. basically what i'm trying to do is set up a limited palette of colors that can be used to draw the polygons of my model - it's inspired by those old Super FX games, like Star Fox (if noone knows what I mean, it's ok) but basically what i've tried is set up an ink n' paint material with a gradient ramp attached to the diffuse parameter, and set up my colors there and set the Gradient Type to Lighting and the Interpolation to Solid. oh and i set the ink n' paint's Faceted ON. what i get is really really close to what i want, but the problem is i just want solidly-colored triangles, and i get "in-betweenies", where some triangles will have two colors. it doesn't look that great.

i guess basically what i'm looking for is if anybody knows a good plugin or other solution that'll get me REALLY flat-shaded polygons.

Hi there, if i understand right, what you want is having each triangle flat with a color, out from a limited palette ? What about a MultiSuboject material and assigning material Ids ? Can be a little tedious though, depending on the number of colors you'll use, but you'll also be able to use ink n' paint materials if you will.

Hi, there is a way to do this. The setup is very similar to your setup, only you'll have to find a way of using self-illumination.

This is the step-by-step, it has no ink lines though:
- New material, put a Gradient Ramp in the Diffuse slot.
- Interpolation Solid, type Lighting.
- Add colours.
- Set the material itself to faceted.
- Set the Self-Illumination to 100.
- Done.

To add lines you could render a white toon material with black lines and composite the image onto your colour image in Photoshop, for example.

End result:

You can get the faces to show up with Ink 'n Paint by selecting the object, converting it to Editable Poly, selecting all polygons and then press Auto Smooth. You'll have to set the angle spinner next to the button to 0.

Good luck,

- Rens
