You will learn how to install Unreal Engine, navigate the 3D viewport, create materials and worlds, sculpt landscapes, paint foliage, program in Unreal using Blueprints, and end with creating a photorealistic world in real time. Unreal Engine tutorial for beginners! In this free tutorial we will go over everything you need to know to get started in Unreal Engine 4. Post your questions or views below in the comment section.UE5 has released and above is a link to the updated version of this tutorial. Trick is to convert everything into parameters and then instance that material for tweaking.

I took VRay’s principle of “Fresnel” IOR function and applied it to reflection, refraction and opacity values. Now you can use this version in your scene and at the same time tweak the values to your liking. Right click the material and choose ‘Create Material Instance’. Now save the material and create an instance in the Content Browser. Add a Constant Parameter to this fresnel’s power and name it ‘Power’. As a final step, we’ll add a Vector Fresnel Function to the alpha slots of our Lerps.Lastly, values of Refraction Front and Side as 1.2 and 0.8 respectively.Values of Opacity Front and Side as 0.005 and 0.2 respectively.Set the default values of Reflection Front and Side as 0.05 and 1.0 respectively.Name the A slots as front and B as side, with the property name they’re connected to as well.

Add a Constant Parameter to each of the A and B slots of our 3 Lerps.

These 3 will then be controlled by our single fresnel power.

Now we’ll add 3 LERP (Linear Interpolate) nodes to the Metallic, Opacity and Refraction slots.

This will allow the light to pass through the glass objects.

Set Lighting Mode to Surface Translucency Volume.

Next we’ll set the global properties of this material in the Details tab on the left.

Convert it to a parameter if you’d like to add some roughness later.

Add a Constant node of 0 value to Roughness slot.

Right-click and convert it into a Parameter node and name it ‘Base Color’. Create a Constant3Vector node for the base color.

Open up this material so we can start adding all the appropriate nodes to it.

Create a folder titled Materials and add a new material to it.

When working in UE4, it’s best to create a separate folder for all asset types.

Glass Base Materialįollow the steps below to create an all-purpose base glass material: This base material would then serve as our master material for all the different instances we might create. Whereas a base material would first need to be compiled. Instanced materials have the benefit of realtime control over your material as you’re changing each parameter within the scene. Then we’ll convert some nodes into parameters for our instanced materials. We’re going to setup our glass material by first creating a base material.

This method can be a pretty good basis for creating something even more complex, cause when it comes to glass, there can never be enough tweaking! Let me teach you my own method of creating a realistic glass material in Unreal Engine. But since Unreal Engine is a realtime editor, you can try as many variations as you like for creating the perfect glass look.

Not to mention how much it taxes the system while rendering. Even in 3ds Max and VRay, creating a glass material can be somewhat tricky to get right in the first go.
