Applying material effects

- In this particular video we're going to take a break…from creating the version of our aged concrete substance…that we will be taking into the unreal engine,…and focus for a few minutes on how we would go about…adding geometry specific effects to our substance…that can add a wealth of detail and believability…to the project that we're working on.…Now we will be using the simple shader ball mesh…that we have been working with here…to demonstrate how we go about doing this.…Even though of course in the end we wont actually be taking…this particular mesh into UE4.…

So when we talk about mesh or geometry specific effects…what exactly are we talking about?…Well imagine for example that we're working with a model…for an all-terrain vehicle or metallic robot,…that needs to have wear and tear in the textures…adding to some very specific areas on the model.…Maybe there is oil leaking from broken pipes or joints.…Well whilst a generic procedural system may be able…to help us out, it oftentimes makes more sense…to create such effects from information taken from…
