I have a problem with using variables. When I create a Point as a feature and use it as a variable Pose, Polyscope adds ‘\_const’ to the variable name.

In Polyscope version 5.5 this problem does not occur, but in 5.6 and higher it does.

The problem is that the assingment does not work.

Is this a bug in Polyscope and is there a way to work around?

Hi @anon45059026 and @anon4868794,

In the post list the \_const instances is available. The script writer will output the value stored in the installation for the specified feature.  
In the Variable list it is available **without** \_const, using that the script writer will output the name, so if the value is modified run time, that is what will be used.
