Code for opacity

Dear All,
I'm looking for some help with c# for the following:
- I have a scene with an object and want to be able to remove opacity with a slider in order to see thru.

Regards

When you say object, I'd guess you mean a mesh with the standard material on it?

Make a new material in your project, drag it on to the object, select Surface Type: Transparent from the drop down boxes on the material.

This already has a slider if you click the base color on the material, and move the alpha slider.

If you want to change the material color via script, get a reference to the object's material via the Renderer component and set its .color property to whatever you want. Add the Range attribute to a public field to make it a slider if you one on your C# script.
