A port of Creates glasslogging feature from 1.14.4
This mod adds the option to add glass panes to slabs and stairs (and depending on config other blocks too). It can be used to create some amazing looking intricate structures.
Which blocks can accept glass panes is configureable in a block tag.
Have fun building with this mod, and feel free to put it in packs as you want.
Special thanks to Simibubi and the Create team. Simi gave me an introduction to modding in the first place, and helped me out with this mod when i had questions about rendering.
