# Overview
This tutorial assumes the user has a basic understanding of Materials.
In this tutorial you will learn how to create a simple two-sided foliage material for your projects. Nearly every output will be converted into a parameter for instancing.
# Setup
1. Create a new blank project with Starter Content.
2. Create a new Default Level
3. Place two of the 'SM_Bush' actors (found in the Content Browser) side by side on the floor within the level.
4. Locate and duplicate the Material used for the 'SM_bush' and rename it to something like 'M_TwoSided'
5. Set the Blend Mode to Masked, the Shading Model to Two Sided, and check the Two Sided option.
6. Now create a Vector Parameter by pressing the 'V' key and clicking in the material graph. Name this Subsurface Color.
7. Create a Multiply node and plug the Subsurface Color into the 'B' input and the Diffuse Texture Sample into the 'A' input.
8. Plug the result of your Multiply into the Subsurface Color input of your material.
9. Create another Multiply node and plug the Alpha channel from the Diffuse Texture Sample into the 'A' input.
10. Create a Scalar Parameter by holding the 'S' key and clicking in the material graph. Name this 'Opacity' and plug this into the 'B' input of your multiply.
11. Plug the output of your multiply into the Opacity input of your material.
12. Create two scalar parameters and name one Specular and one Roughness. Plug them into their respective inputs of your material. Apply and Save!
