I was experimenting with TPT and made a CLNE STKM that clones PHOT. Then, I typed "!set type PHOT BRAY" into the console, and the PHOT became this Strange BRAY that stayed there for a while before disappearing and leaving some BHOL in it's tracks.
this is caused by any solid particle or whatever particle being overlayed more than 5 times if its out of the hole something wall
certain objects bypass this such as photon thdr and other shit
short answer you just overlayed bray multiple times
