how is your black hole or gravity pump placed, and how strong is the pull? it might just be that the photons are moving too fast for the gravity to effect them
why don't you put a link to your save or what have you so i can see it in action, to see what you mean
uhh ok why don't you try using GPMP? i never have problems with it, but i am not sure with BHOL and WHOL because i don't really use them for curves
the few times i do use WHOL and BHOL i do have this wierd phenomenon that causes the photons to make a wave shape, but i found that this happens because of reflected photons behind the clone, so i usually place a void right behind my PCLN
hmmm... did u place void behind the clone? i cant open the save, im on my ipod and i see a pic of a dog with the words “I DUNNO LOL” over it, and “Save doesn't exist” underneath
EDIT: uh... when i first posted this, i saw what i described above, but now i see your save's screenshot
if you put the laser emitter inside a Gravity Wall box it makes the beam more stable. The gravity is probably causing the PHOT to interact with the emitter in some way.
when i posted my first comment on this topic, it showed the dog before i pressed “Post” and after my device loaded my comment to my screen, i saw what the save was supposed to be, a laser with something like 5 black holes directing the beam
EDIT: and even this post did it, up until i edited it
