Importing PLY file with color scale associated to a numerical "user scalar"

Operating system: Windows 10 Enterprise
Slicer version: 5.6.2
Expected behavior: Display Colors Corresponding to Facet User Defined Values
Actual behavior: No Color

Hi to the 3D Slicer community.

This post is in relation with Importing PLY with Color

I have been struggling quite a lot trying to import a PLY file containing a model with a numerical (float32) “user scalar” (called “myscalar”) associated with each model’s facet into 3D Slicer.

The model is nicely displaying but I am trying without success to apply a color table corresponding to this scalar value.
I even feel like my user scalar is not considered at all by 3D slicer.

What I managed to do is to correctly display colors for a given RGB triplet associated to each facet in the PLY file but, then, I find complicated to link back this color to my user scalar that I would like to be shown in the color legend.

Here is the header of my PLY file :

ply
format ascii 1.0
element vertex 1576
property float32 x
property float32 y
property float32 z
element face 394
property list uint8 int32 vertex_indices
property float32 myscalar
end_header

Would anybody on this forum be so kind to help me displaying my model with a color scale corresponding to my user scalar variation through the model facet ?
