How to key off a material?

[robcat2075]

This test model has several groups, each with a different color, and one "all" group, containing a gradient material, that overrides the color groups to make a gradient from black to white.

GradTest01.prj

Is there a way to key off the influence of the "all" group on a certain frame to let the native colors of the other groups show through?

Perhaps some form of expression?

..|..|..|GroupAll|Shortcut to graydient|Gradient|Attribute.Surface.Diffuse Color.Red

Here's something of a proof of concept with the Red channel of a material in one model driving the red channel of a Group in another mode.

Not quite what you are after but might hint an a solution.

Can you tell me a bit more about what is happening?

[robcat2075]

i guess there was a translation problem.

I wasn't trying to key off a material, I'm trying to key OFF a material.

If you were pressed for time you could just put a copy of the model slightly in front of the first and fade the copy out.

hmmm..... 

You could adjust the Displacement percentage from 0 to 1.

0 will present the color(s) of the material

1 will decactivate the color(s) by activating the displacement but so minimal that it cannot be noticed.

Gah!  Disregard.  It doesn't allow the Groups to show through.

You may be experiencing why I tend to prefer Patch Images over materials and decals.

Dan, i presume that is an actual 2nd model and not a 2nd instance of a single model, right?

[Wildsided]

Yeah, sorry. By copy I meant a 2nd model.

That would work for many uses but  in this case i'm trying to find a way to keep it all on one mesh.

thanks none-the-less!

This might work...although I made the transition too fast and sloppy.

I'll bump this in case it was missed.

That is a clever solution, David. Thank you!

Thank you, Dan and Rodney for your contributions also!
