If two geometry files are loaded, and they color by same scalars name, here is a problem?

I have loaded two geometry files, they are like this.

1. Vessel.vtk
2. Segmentation.vtk

When I show them at the same time and all color by scalars. It will like this, they are rendering by one colormap.

It seems that they are using the same ~representation~lookupColorTable(I have read the code), is it a deliberate design？

I see, thank you very much.

Same field name should have a shared color scale otherwise you could not compare the temperature of 2 objects accurately. If you want to get independent coloring for meshes, you should not name your field scalars everywhere. You could use the name of your geometry assuming that one is unique.
