I need help with scaling issue inside of Maya involving Displacement maps. I exported 32 bit maps and used Scott Spencer’s expression solution for scaling displacements (= -file34.alphaGain/ 2 
and so forth.
When I scale a single subtool in Maya the expression works beautifully, but when I group all of my subtools in Maya and scale that up, the expressions will not change from the standard 1.00 and -.5 numbers, and they lose their details at render time.
Please take a look at the images. Any help would be greatly appreciated. Thanks!
