Alrighty, reproducing: 1. Add Suzzanne 2. Delete half of her. Add mirror modifier. Add particle system in the particles panel. With the particle system after the mirror modifier in the modifier stack, the particles are only emitted from the mirrored side. But if they are in the opposite order the particles are emitted from the "real" side this bit works as expected. I've attached a. Thanks Matt. Particles and constructive modifiers don't really mix well together as particles are emitted from the mesh surface using the mesh's non-modified structure.
To find more about the Starter Content, please check out the Starter Content documentation page. Once you have located the mesh, Drag and Drop it from the Content Browser into the level.
Once it is in the level, set its location to 0,0,0 in the world. When completed, your level viewport should look like this. Now that the Static Mesh has been placed in the level, we can now apply our Subsurface Material to it.
To do this, first find the Subsurface Material in the Content Browser. Once the Material has been located, Drag it from the Content Browser on to the mesh to apply it. Now that the Subsurface Material has been applied, it is time to tweak the settings of the Material Instance.
In the following sections, we will go over how we can control how our Subsurface Material will look and how to tweak the various options in the Material Instance to get the results that we want.
In the current setup of our Subsurface Material, the Opacity input controls the amount of light that we want our object to scatter. A setting of 0 will allow all light to scatter where a setting of 1 will let no light scatter.
The following example shows the back of the chair mesh with the Opacity value set at 0 in the image on the left, 0. Notice as the numbers go from 0 to 1, the amount of light we see passing through the object becomes less and less. While the Opacity does help to get rid of a lot of the scattered light, you might notice that there is still some Subsurface scattering happening.
To get completely rid of the effect, you are also going to have to adjust the Value of the Subsurface Color More on this in the Subsurface Color Value section below.
While you can adjust the amount of Subsurface scattering that happens via the Opacity input, you can also adjust this using the Value slider in the Color Picker. For example, setting the Opacity to a value of 1. If you do the opposite of this, adjusting the Value slider in the Color Picker so that it is now in the White, you will re-enable Subsurface Scattering like in the example below.
Here is an example of adjusting the value in real time. Notice how as the Value of the color is adjusted from Red to Black, the amount of Subsurface scattering influence is affected. You can use a Texture as a Mask to have more control over what areas receive or do not receive Subsurface scattering.
To do this, all you need to do is plug the Texture you want to use as the Mask into the Opacity Channel of your Material. In the following example, not only are we using a Mask texture, we are also using a Scalar value to control the intensity of the Mask so that we can have more control over the amount of Subsurface scattering that is happening.
Mask textures work based on values going from Black to White. Values that are closer to Black will allow the Subsurface effect to come through while values that are closer to White will not allow the Subsurface effect to come through. Here is what the Material above, using the Mask Texture, looks like in the level. Petar Kostov petersk.
