MPM_can't visualize results of particles

Hallo,
I'm using MaterialPointMethod and save the results of the material points inside the result file. The file head Looks like this:
GiD Post Results File 1.0
Result "MPMDisplacement" "Kratos" 0.005 Vector OnNodes
Values
And the file head of the mesh file (contains the coordinates of the material points) Looks like this:
MESH "outmesh" dimension 3 ElemType Point Nnode 1
Coordinates
In GiD I merge the mesh file and the result file. Then it's possible to see the materal points (style: boundaries) but I am not able to see the results of the material points. You see a changing legend but the material points stay gray and at the same Position.
What could be the problem or missing Preference.
Peter

Go to Utilities->Preferences... Postprocess->Mesh elements
and try the different options of 'Point element' and 'Sphere elements'
Try also changing
Utilities->Preferences... System->Drawing method, about draw points and spheres as textures, or as mesh.

Your second suggestion change nothing. And according to your first suggestion, I can't find "Mesh elements" in the Postprocess-Part under Utilities->Preferences.
Perhaps this is also a question of version?? I'm using GiD 12.0.7.

off course different versions of GiD could show different behavior
attach a zip with an example of your mesh+results

Attached you can find the mesh and results.
Thanks again

First suggestion: instead of provide different prefix names to the .post.msh and .post.res files, and then have to do two steps to be read (read the mesh and the merge the results file) why not use the same name, and then must only read it (selecting one of the the other is implicitly selected by its name)
And also better, if do you have also a .gid folder model, using the same model name the .post.msh is uneeded (the mesh of preprocess is used) and when changing from pre to post the results are automatically read, it is not necessary to explicitly open/import them in postprocess.
About showing results, I am able for example to show (GiD 12.0.11) this contour fill of the modulus of the vector result MPMStress

you can see that I have set a a big point size to appreciate the result.
GiD 12.x: Options->Geometry->Point options...
GiD 13.x: Utilities->Preferences... Postprocess->Mesh elements- point element options
and this animated gid of a deformed result
Window->View results - Main mesh - Deformed (and select a vector result), and Window->Animate... to do and save the animation along the time steps

Thanks a lot. Now it works!! I will also follow your advice regarding the file names.
