3dsmax Vertex color mass change?

NAIMA

Let's imagine we have a model all vertex painted in one color with different grade tones , Is it possible to shift the hue of the vertexes from for example a gray to a blue one in order to not have to repaint the whole model by scratch ?

This might help. I've never tried it myself, but I've seen it around.

http://www.scriptspot.com/3ds-max/scripts/vertex-color-tools-0

reads: "Adjust R -G -B -H -S -V -Contrast"

I think that script is now part of max or am I wrong? It should be doable what you want to do with standard tools. Just go trough them. Opening Help reveals also a lot about not that much used features..

NAIMA

do you have a direct tool sugestion?

NAIMA

Indeed in the vetex paint window it seems ot include lots of those features in the plugin but how do I do to mass change that color from a gray to a colored one?

Just tried the scripts and they work only on a library of function that is outdated and no longer available anyway planned for max 4 ... so is there another way atm ?

well, i once made some clouds having baked in lighting and there was a technique that might work for you.

1. unwrap your model automatically
2. render to texture your vertex color
3. change the map in photoshop (hue/saturation)
4. import the new texture into max again
5. apply it to the mesh
6. apply a vertex color modifier to the mesh
7. (now i'm doing this off the top of my head, so bare with me that i dont know which button to click) inside of the vertex paint modifier you can change the vertex color to the new map


or another way, but i dont know if that helps in your case:
try adding another vertex modifier on top of the first one. make it the color you need and change the blending mode. it will blend over the old vertex paint.

I tried the second but I can't get rid of the first , even filling in deletion doesn't work to remove .

how to I render to texture the vertex color? and then how to reapply?

you shouldnt get rid of the first vertex color. you should use it as a base to blend over a different hue with another vertex paint modifier.
