Make 3D for RTDose

Hi

I want to make a 3D shape which show color by value range like volume
I have a RTDose dicom file and I want to make a 3D shape like this:

I tried that with volume . setting opacity and color of each range of value in volume property is so easy but the result was not good Because the colors are mixed together and I can’t see the layered color like the picture above.

so how can I make a 3D shape to show Dose value ?
( and how I see that in 3 Axes ( axial , sagittal , coronal) or how reslice that)

thanks for your help :wave: ;
