Verte Color Use in Maya Questions.

verybad

I'm not really experienced with vertex baking, but It's something I'm tryign to get a bit more knowledge about.

I have no problem with baking vertex colors- that's pretty simple, but I'm having a problem integrating them into a shader path so I can see what I'm doing while I'm still playign with the object in Maya. For example, I may want to bake lighting or occlusion into vertexes and have that as a multiply on a regular texture based object. Except I'm not seeing what I'm doing 8(

I've done this plenty of times using a baked texture so...how do I get vertex bakes to be blended using modifiers rather than 100% ?

Are you asking how to fade the vertex bake, or adjust it's HSV?

You can blend in vertex data from the settings in Display > Polygons > Custom Polygon Display. It's called "Color in shaded display". That's for the viewport, if you want to render it you will have to do it with mental ray and it's a little tricky to set up.... think I have a screenshot of it somewhere if that's what you want to do...

also make sure that in the "right mouse on your object"--->color sets--->color set editor ----> display ---> all its set to:

"color material chanel ambient + diffuse" !

an ao bake often resets this value and makes your vert colors over rule your texture !

vertex colors are extremly powerful and way under appreciated ! even autodesk doesnt properly maintain all the vertex color related tools in maya there is a trillion reproduceable bugs in the color set editor !

Yeah, I've seen vert colors in action and it seems like something I need to know. Too late to try out now, but something I will run through tomorrow. Thank's everyone for responding!

The engine I've been using for a long time was DX6, diffuse colors and alpha transparency/blending, and that was pretty much it. Need to get ready for an upgrade to more modern stuff.

I wouldn't call vertex lighting modern, it's been around for quite some time, we used it a lot on ps2 it's quite a painful way to make lighting.
