However, we have a huge benefit with this method. We are also unable to commit the displaced geometry to the object and, for example, export the displaced mesh. This only works in Cycles and since the displacement is calculated at render time we can only see the displacement in rendered viewport mode. The second method is to use the displacement socket in the shader applied to the object. This is probably the easier method to use since it is more straight forward, and we get feedback in the viewport without having to render.

We can also mask our object using weight paint and a vertex group to control where the displacement is applied on the object as well as the strength. We can also apply the modifier to have the displacement permanently committed to geometry. This means that we can see the result in all view modes in the 3D viewport. The benefit of using this method is that we displace beforehand as part of the modifier stack. It is a bit limited in some regards while still flexible in other ways. This is the traditional way of using displacement in Blender.

The first one is through the displacement modifier. In Blender, we have two different ways we can use displacement. Two ways to use displacement in Blender and the difference between them Therefore, you don't see displacement maps used as often for real-time applications or games. Since displacement needs a lot of geometry it is also heavy on performance. So you can see that a displacement texture lives somewhere in the mid level detail area and can be a good option if we want detail in the silhouette. Therefore, if the detail we want to create is too small we may be better of using a normal map instead.ĭisplacement can also change the silhouette of an object and if that is our objective a normal map is not enough. The most common scenario where we use displacement is to give a surface a kind of mid level detail that would be too time-consuming to sculpt or model.īut displacement also requires a lot of geometry to be able to displace enough to create the detail. This way we can move any vertex in any direction instead of just up and down as is the case with traditional displacement. Then we map the Red, Green and Blue channels to each of the axis in the 3D world. We will not cover it in detail in this article but the difference is that we use a color texture instead of a black and white texture. The second method is vector displacement. Using Displacement together with Diffuse, Roughness and Normal map textures In this way we can create real geometry changes with a texture and gain high level detail. Displacement texture to the left and applied to a subdivided plane on the right.Ī lighter value will move a vertex further up from the original position while a darker value will move the vertex less. This is when we use a black and white image texture or procedural texture to change the position of the vertices up and down depending on the gray scale value in the texture. We call the more traditional way just displacement. Traditional displacement and vector displacement. There are primarily two ways we can do this. What is displacement?ĭisplacement is a way to add extra detail to an object by changing the position of the vertices in an object.

We will dive deeper into displacement and look at this method in more detail as well as the second method we can use through the shader in Cycles. For image textures browse for your texture then go back to the modifier stack and adjust the midlevel and strength. Here we select the kind of texture we want.

How to use displacement in Blender? Select your object, add a displacement modifier. Since Blender 2.8 we have two methods of adding displacement, and we will cover them here. In this article we will take a look at what displacement is and how to use it in Blender.
