+* This is a clean, fast, modern and free Perlin Simplex noise function.
+* If we change float to double it could be even faster but there is no double type in Blueprint
+* All Public Functions are BlueprintCallable so they can be used in every blueprint
+
+From DevDad and Dedicated to you and Unreal Community.
+Use it free for what ever you want.
+I only request that you mention me in the credits for your game in the way that feels most appropriate to you.

+and modified to fit to Unreal Engine 4
+
+
+* This is a clean, fast, modern and free Perlin Simplex noise function.
+* If we change float to double it could be even faster but there is no double type in Blueprint
+* All Public Functions are BlueprintCallable so they can be used in every blueprint

+
+From DevDad and Dedicated to you and Unreal Community
+Use it free for what ever you want
+I only request that you mention me in the credits for your game in the way that feels most appropriate to you.
