In short, I want to have a prop_dynamic appear to fade into and out of existence, regardless of where players are stood. So they could be right next to it, and the prop would fade in or fade out without the player moving away from it. To be clear, I am NOT talking about the fade distance settings that are used to optimize when a prop is rendered. For my prop I will be keeping them to the default for the time being. Now I have achieved this to some degree, by setting the prop's render mode to 'Solid' and the 'FX Amount (0 - 255) set to "0", then sending 'Alpha' inputs to it every few seconds. While it works, it feels a bit 'hacky'. What I'd like to know, is if there is a better way to achieve this, ideally so it's a smooth and gradual fade in/out. At the moment I am having the prop fade in over 5 seconds, with increments in the alpha value every second. (0, 51, 102, 153, 204, 255) Short of adding more inputs, is there a way to make the prop fade smoothly?
