First things first, I’m new to unreal and I’m sorry if you might cringe at this post.
So, I was following this water caustics tutorial Unreal Engine 4 - Water Caustics (Faking Light On the Bottom) - YouTube , finished the material but then I wanted to change the color of the material so I tried the simple method with a Blend and a VectorParameter even tho it was Texture Object, and then I got this https://i.imgur.com/2ZRszxK.png and I didn’t know what to do.
Also, here’s the whole material if it helps https://i.imgur.com/2biqEcM.png
