Hi Michał, Just to clarify the previous answer. Surface color will only do a gradual coloring, not discrete. However, you can approximate the discrete coloring with somewhat more effort, by putting the same color at the top and bottom of each range, for example: white 0 white 0.99 red 1.0 red 1.99 […] You can also try using a finer triangulation on that surface cap although that will increase the computational load for moving the clipping plane and rendering the colors. I hope this helps, Elaine ----- Elaine C.

How can color volume by value with binning several values into single color?

I achived the effect partialy by opening several times the same map. set different thresholds and colors to each one and playing with Per-Model Clipping tool, but it have some drawbacks. Planes can't be at exact same level because I observe artifacts. So I tried to move slightly inner layers upp, but still I observe "staris" effect.

I also tried with Surface color tool, but it uses interpolation and blends colors togather.

In other words I need something like this: https://1.bp.blogspot.com/-5B5ueLHCBPY/T4II4IddvwI/AAAAAAAAB_w/rYwqsJNldY0/s...
