Unity 2019.4 Shader giving weird results

[fasihrana]

So, I opened up your project and was pleasantly surprised by how good the clouds looked. Then I tried to integrate the clouds in a new project using just the Noise.png and the code in clouds.shader. The result I'm getting is somehow distorted or not quite filled in. I wonder if you did something extra to get the clouds looking right in your code.

I should also add that I'm quite new to Unity and shaders in general and this is more a "help if you can" type of question.
