I'm trying to install the Density Checker addon. I'm adding TexTools just fine, it's box has been checked in the addons menu. However adding Density Checker the same way doesn't add it to the menu's list. Is there something I'm missing? The only difference between what's shown in the video and what I have is that my zip folder is named "Blender-Texel-Density-Checker-master.zip" instead of "Texel_Density_2023". Is that important?
