VFX particle invisible on a certain perspective,


I made the mesh on blender with backfaceculling on it and import it to unity. In unity I change the the normal option into calculate. then I made it into three part, one the base black slash, then black fade extension, and the light which looked invisible on a certain perspective. it doesn’t looked invisible on the right side, only the left side for some reason. I can’t get any solution to this, I would really appreciate it if you could help me!

for anyone that might had the same problem as this one, I only change the value of the sorting fudge of the glow part into -1.
