How can i get Natural gradient color closed polysurface material? for export

Hi, Guys

I wanna get natural gradient color with closed polysurfaces.

So, I serched "bakeMostAttributes9014.ghx" this forum.

But, i can't use this well.

Problem is i like bake with closed polysurface.

but there is no option(bakeMostAttributes9014.ghx)

i just, add "geometry" and bake, result was no good (geadient problems...)

I hope , get the natural gradient color materials with 300 over closed polysurfaces.

and export to orther render tool(for ex_Lumion)

Please help...

best regards..
