Mini Tutorial - How to change the dirty state overlay image

Introduction

This tutorial will show you how to change the overlay image used in the dirty state using Sims 4 Studio. This process can also be applied to the burnt state.

This tutorial will not show you how to create a new texture. For further help getting started please see the Build/Buy/Tuning tutorial list.

Q: Can I add a dirty state to an object that doesn't have one?
The answer is... YES! Yes you can. It will be easiest to start with only one swatch in your .package and for the most part you will just follow this tutorial. You will have a few more steps between steps #4 and #5 and I suggest comparing an object that you know already has a dirty state (microwave, counter, etc.) to your current project.

What you will need

Sims 4 Studio

Instructions

Step #1 The dirty state is defined inside the model resource along with the burnt state. First go into the warehouse and add a new DstImageResource to the .package and import your dirt overlay texture. To get to the reference you have to go a few steps deep. Click the Edit Items button next to Lods on the Model resource.	Click to see larger.
Step #2 Next click Edit Items next to Meshes.	Click to see larger.
Step #3 Select one of the meshes that is not the dropshadow. (In this example I used a counter and the name you see is the shader used. Usually this will be phong.) Scroll down until you see Material. Click Edit Items next to Entries.	Click to see larger.
Step #4 You will see a long list of variants and states if you already have multiple swatches in your .package. Each swatch has 3 states: Default, Burnt, and Dirty. SPOILER: Click to show {Don't Have a Dirty State? Click Here} If it does not have one COPY the burnt state and change a few things. The first thing you need to change is the MaterialName (generate one with the hash generator in the tools menu) then scroll to the bottom and you will see StateId change this to EEAB4327 = Dirty state. Once that is done just continue with the rest of the tutorial. Select the dirty state and click the Edit Items button.	Click to see larger.
Step #5 Once inside you will see the reference to the dirt overlay. You will need to change this instance on ALL swatches and ALL counter parts on ALL Model/lod resources to the one created when you added the image to the package.	Click to see larger.
