Hello all, is there a way to change the color of multiple objects without having to change all their materials 1 by 1? What I am trying to achieve is making the object green if it can be placed at the current position(building system), or red if it cannot. However, right now I need to open all materials and make the color as a parameter, and it is time consuming. Is there a workaround?
You could use a Material Parameter Collection, perhaps?
Seems interesting thanks, although I was looking for a way that I don’t have to edit every single material. Like I got a campfire object with 4 different materials, and I need to edit all 4 materials just for 1 object, and it’s really time consuming. This might come in handy tho, thanks 
Look at postprocess materials, there is example of outline material (google it). You could modify it to cover whole mesh not only edges.
Thanks, I tried this outline material and it works great but I am having trouble making it work for the entire mesh. Could someone guide me a little bit?
This is the entire code.
and I assume some changes need to happen here:
Any tip will be appreciated
Is it possible to also reduce opacity using post process? I looked in google but couldn’t find any valuable information
