Hi there thanks for your comment , your concers are true, but the previous versions of the shader works perfectly fine without any bug, only the latest version which is not 20 USD, it is actually 30 USD has bugs in it, and I don’t recommend anybody to purchase it. I will probably restrict the latest buggy version of the shader, so that it won’t cause any confusion. So when you look at something buggy you might also look at its previous versions, Coppercube itself has so many bugs since version 1 and yet are not fixed, but I am working on finding a solution to fix the bug. The shader works as expected but when you have huge scene with tonnes of lighting you will face FPS drops. Functionality wise there is no bug in the shader, but I don’t want people to purchase it and then later encounter the performance issue. I will probably hide “version 4” until I find a solution for the performance drop.
Thanks :) You should spend your money on buying assets for your games or to purchase other extensions or things that might be valuable to you.
