[Qgis-user] QgsMeshLayer: Copying a MeshLayer style from an available dataset to another layer

[Saber Razmjooei]

Hi Christian,

It is logical not to be able to copy and paste style if the mesh datasets
are not the same. It is consistent with the other parts of QGIS, for
example, you can not copy and paste style from a point layer to a line
layer.
My suggestion is to save the color ramp from hydro_as-2d (2nd layer in your
layer tree) > Submersion and apply it to hydro_as-2d (1st layer in your
layer tree) > Submersion.

It might be useful to file an enhancement ticket, so that if a mesh dataset
name matches, the style can be used for that specific dataset.

Also, worth upgrading to more recent versions of QGIS.

Kind regards
Saber
