How can I Rescale a ColorFunction on a 3D plot

I'll like to know if there is a way to do this colorfunction scaling on 3D plots

    Plot[0.8 Sin[x] + 0.2, {x, 0, 3 [Pi]}, 

ColorFunction -> (ColorData["Rainbow"][Rescale[#2, {0.2, 1}]] &), 

ColorFunctionScaling -> False, PlotRange -> {-1, 1}]

then we got the color function scaled

enter image description here

I'll like to do the same in 3D on this case

 Plot3D[Sin[x] Sin[y], {x, 0, 3 [Pi]}, {y, 0, 3 [Pi]}, 

 ColorFunction -> (ColorData["Rainbow"][Rescale[#2, {0.2, 1}]] &), 

 ColorFunctionScaling -> False]

But something terrible happens, it is scaled on x and y but not on z

I thik that I solve it using this Plot3D[Sin[x] Sin[y], {x, 0, 3 [Pi]}, {y, 0, 3 [Pi]}, ColorFunction -> Function[{x, y, z}, (ColorData["Rainbow"][Rescale[#, {0.2, 1}]] &)[ z]], ColorFunctionScaling -> False]

use (ColorData["Rainbow"][Rescale[#3, {0.2, 1}]] &)?

Plot3D[Sin[x] Sin[y], {x, 0, 3 π}, {y, 0, 3 π},

 ColorFunction -> (ColorData["Rainbow"][Rescale[#3, {0.2, 1}]] &), 

 ColorFunctionScaling -> False]

enter image description here

An alternative form is ColorFunction -> Function[{x, y, z}, ColorData["Rainbow"][Rescale[z, {0.2, 1}]]].

Alternatively, you can specify the range of the color function in ColorData and omit the function argument (the default color gradient direction is z):

Plot3D[Sin[x] Sin[y], {x, 0, 3 [Pi]}, {y, 0, 3 [Pi]},

 ColorFunction -> ColorData[{"Rainbow", {0.2, 1}}], 

 ColorFunctionScaling -> False]
