Materials looking weird!

Hey there.I am making a 3d game and i got a ton of objects that have different color materials on them.I want to make them fade in when something happens and to do so i need to set their rendering mode to fade from opaque but in game they looks super weird since you can almost see through them.I was wondering if this is fixable?I mean i still want them to fade in but do i really need to make change their material rendering mode for that?Can’t i make them look normal but still make them fade in?Please help me solve this thanks in advance!

This should be quite easy with the Standard Shader and an animation attached… can you attach an image of what is looking “weird?”
