I am a beginner, and I am working on a basic weather system where the skyboxes change, and particle systems stop/start based on what weather pattern it is. But when the skyboxes change, they just blink in and out and it would look better if they faded. I know about a million other people have asked this but my skyboxes are made with 2 shaders and are not cubemaps so I cannot do a shader because you cannot add a material on a shader graph. What should I do to make them fade into each other?
Thank you for your help in advance on this topic.
