Fail to change material of selection in rhino 8

Rendering
1

Want to do the most basic thing of changing my selection to glass. i’m not even customizing anything. but the material is not changing at all. for context, here’s the steps i took:

  1. in the drop down menu of the materials tab, i clicked on select objects
  2. i selected the object and pressed enter
  3. i clicked on glass, which is already a preset.

can you post a file?

are you making a glass material, then selecting an object then right clicking the material and using “assign to selected” ?

you can also drag and drop a material onto an object in the modeling window.

this is working here as designed.

Uh, can you to send a video recording or list step by step of how to apply a material to the selection? Thanks.
if it helps with troubleshooting, here’s my file. and i want the glass to only be applied to certain faces

ah my bad. it turns out that the material did in fact change. it just that it was only reflected in rendered view but not in shaded view.

Materials are rendered in Rendered view and Raytraced view.
