This issue is simple: When I use SlashBladeResharped(1.1.16) and Photon shader Pack together, the sword in mod does not display.To be more precise, they seem to become transparent.I tried using an earlier version of the mod(1.1.4), and the issue didn’t occur. So, I believe this might be a new issue caused by the recent update.

These are the mods I used during testing:

Fixed in 1.1.18
