  • That's awesome,true color correction, nice one Animmaniac

  • That is amazing. Well done and thank you!

  • I really liked this effects. But it's really weird. If I set values on startup they effects as normal. But if I change the values on runtime(for day/night cycle) than It effects very odd. I add 100 to value, but it effects like 10000. Or I set rgb highlights to 100. Than I decrease it 25 4 times. if it becomes 75 than it effects like 750. when it becomes 50 it effects like 750 again, when it becomes 0 than it effects like 0.

    I couldn't resolve reason of this oddness.

    Are you sure it's not your maths? You can only set absolute values and there's no way to retrieve current parameters... For me, it works flawlessly. Thanks.
