My team is creating a game with many levels,and one of the levels is just a mansion. In the mansion I have 3 rooms in different locations(the manor is big) where I have 3 planar reflections,one in each room. The size of the planar plane is small(we are talking for bathroom mirrors, the scale is something like x=0,002, y=0,0025, z=1). The problem is that the FPS drops from 100 to 22 in unlit mode. The settings for each planar map is low after I did a research of what does each setting option.
So my question is,Is a limit of planar maps that you can use.And if not,what should I check to increase the FPS? If you require any images from the project to help you with my problem,please let me know to attach it.
Thanks in advance
