Why when i have the shader ON the distance of the clouds are capped to the render distance? I want to see clouds all over the sky like in vanilla (even with 2 chunks of render distance i see clouds all over the sky). Is there any way i can make this happen (i dont mind editing the code, i just dont know where :( )?

I understand. To temporarily solve the issue, you can use the clouds provided by the shader instead of Minecraft's native clouds.
