Make Layer Visible Again After Effects
A few years later my first light saber, I learned how to track footage, and then eventually I was able to put in a cheap animated 3D spider robot... I was getting to the place where I thought I knew the nuts of After Effects pretty well. Then one twenty-four hours my professor at college told u.s.a. briefly about render social club in Later Furnishings... I found this fascinating and wanted to know more. Today we'll practise some experimentation and become through Later on Effects' return club!
What is the Render Guild ?
Information technology's but the way After Effects proceeds from the source files to the rendered footage (in the RAM or in a file). In other words, information technology's the order in which all the calculations are made past After Effects in processing your source files to go the rendered footage in your limerick window, or in your exported file.
In order to fully understand this concept, call up that a video clip or a digital (rasterized or vector-based) movie, is just math. If yous remember that a pixel is a minor square or rectangle with a unique color... you are wrong. Or should say, you're not quite right. Before being graphically represented like this, pixels, vector-based pictures and video clips are numbers, the manner all digital data is.
Afterward Furnishings is software which is able to tweak, modify, and alter those numbers in lots of different ways. All the processes are based on algorithms.... Effects are algorithms... the Camera Layer is based on algorithms... Motion Blur is even based on algorithms.
Okay, so everybody already knows that, but what I wanted emphasize hither is that your final rendered video is the result of all the algorithms that you employ on your source footage which is calculated one later on the other. After Effects doesn't show you the intermediate states of the processes on your picture, it but displays the final event. And because Later Furnishings is based on non-destructive editing, learning how Subsequently Effects works is a useful skill that tin can actually aid you amend your workflow.

A Basic Comp, Step by Step
To get a better idea of the concept, nosotros will have a uncomplicated experimental limerick which we tin see below, with layers, a Track Matte, 2 Pre-comps, Effects, an Adjustment layer, 3D layers, a Blending Mode, a Light and a Camera. In a composition, the layers are calculated from lesser to tiptop and non visible layers are not calculated. Don't forget that the composition has a default mono-color groundwork which tin can be rendered if need exist (but it tin blend with the layers, using Blending modes). So, to empathise the render guild of a composition, we first need to sympathize the return order of a layer.
Our cute exam limerick based on the AE CS5 logo.
The First Layer
Here, it's is the AE CS5 logo in PNG format. It could exist any kind of layer or source material. The first step for Later Furnishings consists of decoding your pic :codec, pixels, fields, frame-rate etc...
The AE CS5 logo.
Just after that, comes the Masks. Here is simply a circular Mask around the "AE". The Mask are rendered from elevation to bottom. So if you have two Masks, the 2nd is relative to the offset.
Then the Effects of our layer is calculated. Here we have a Bevel. As you tin run across, the Bevel is applied at the edge of our Mask. It shows that Effects comes after the Masks. If at that place were several Effects, they will exist practical from summit to lesser.
The Transform properties are applied right after the Furnishings. This way, the Calibration, Opacity, Position etc... of the Effects are relative to the layer Transform properties.
Then, in that location is the Blending mode. Here information technology's just the normal mode, because it'due south the bottom layer. The other modes are useless in this position.
Now that our showtime layer is calculated, we can continue with the rest of our composition.
The First Layer of our Comp.
The Residuum of the Comp
Adjacent comes the Track Matte. The Track Matte layer is calculated completely (Masks, Furnishings, Style) and and so the Matte is applied to our first layer. Here, our Matte is a pre-composition, in which the messages of the logo are white. In fact, the Pre-composition is calculated first, before any layer of the composition. Equally yous can see, the Bevel effect is not applied to the letters of the logo. That proves that the Effect of the lesser layer is calculated before the Rails Matte. Note that a Track Matte cannot be applied on a 3D layer if that latter has a Layer Fashion (that's why there is no Layer Style in our first layer). Note also that the Style Layer of a Track Matte does not accept into account if that Track Matte is 3D. Anyways, using a 3D Rail Matte on a 3D layers isn't really a skillful thing, but this is just for the experimentation.
The Runway Matte in Activity.
Next in our composition appears the Light layer. The Light layer deals with the 3D layers, casting their shadows and illuminating them if they are in its beam. That means that the visual advent of a 3D element changes afterwards information technology was calculated in 2D. To avert problems, exist sure that your Track Matte, (if it'due south in 3D) doesn't accept lights and shadows.
Then, Camera layer. I don't retrieve it's necessary to explain how it works hither.
The Light and the Camera.
Next in our composition comes our Aligning layer which affects the layers under information technology (except Camera and Light layers) in a 2D way (it flattens the composition). Below I've applied the Glow and the Curve effects.
The Adjustment Layer : a Curve and a Glow.
Next comes a uncomplicated Grey Solid with a colorful Gradient outcome applied to information technology. Note that the Blending Mode is practical after all process done on the layer, except the Alpha layer.
The Blending mode of the layer come subsequently the Furnishings.
Finally, the Motion Mistiness is applied, depending on the camera movement and the layers motion. Hither, there is none.
Particular Cases
The Continuously Rasterized Vector Layers
For that kind of layer, the Transform properties are applied before the Effects. That ways that the size of the Effects (as a glow, a blur, a fractal racket...) are not relative to the size of the layer. The trick is putting your layer at the correct size, and and so link the "size" (length, radius, or other properties similar that) of your Furnishings to the calibration of the layer.
Don't forget that the Transform properties can exist practical as an Consequence, if needed. Only get to the Furnishings panel and write Transformation. This can exist useful in some cases.
Also recollect that the shadows of that kind of layer don't take into account the Effects applied to that one.
When the Calibration grows upwards, the relative Scale of the Fractal noise stay the same.
Pre-composition
If you check the "Collapse Transformation" for a pre-comp, the Transform properties volition be calculated before the Masks and Effects. It's basically the same thing as the Continuously Rasterized Vector layer. But the indicate here is to collapse the Transform properties of the containing composition with the Transform backdrop of the layers in the Pre-composition, in order to continue the best quality. Be careful: if you put that Pre-composition in a 3D comp, all your layers (in the pre-comp) have to be in 3D (so, no Adjustment layer...).
The Continuously Rasterized push button for a vector layer becomes the Collapse Transformations push for a Pre-composition.
The Shape Layers
With a Shape layer, the group at the lesser is calculated first, and the shape at the bottom of a group is calculated first. Then, the Path operations are calculated from superlative to bottom. So, the Paint operations are calculated from bottom to meridian (they use Blending Modes, similar the layers), but nosotros can change that in selecting "Composite : Above Previous in Same Group."
The shapes at the bottom are calculated first.
Parent, Child, and Link between properties
If a value depends on the value of an other layer (for case, if one layer is kid of an other, or if a value is linked to an other), the reference is calculated first.
Layer Styles
They are calculated from top to bottom afterwards the layer Blending Style, with their own blending way. We could think that, considering the Transform properties are calculated before, the Interior-glow will not rotate if I rotate the layer... Just, the glow seems to rotate as if information technology was applied earlier. To run across what really happens, just put the racket of your Interior glow at its maximum level, and rotate your layer. You can meet that the noise doesn't rotate. The layer styles are calculated afterward the Transform backdrop.
Note that the opacity of the Layer Styles is relative to the opacity of the Layer. One time again, the Transform properties are calculated before.
If you want that the Interior Styles utilise the Blending way of the layer, you can select "yeah" to the Alloy Interior Way as Group in the Advanced Blending options. It doesn't change the render guild.
Layer Styles uses the Track Matte of the layer as well. This one is calculated before the Layer Manner.
The style come after the Track Matte, so after the Transform properties.
Preserve Transparency
This is last process calculated by AE to render a layer.
Deeply understand the Afterward Effects' render order is not such an easy procedure when nosotros take a complex composition with a huge multifariousness of layer types, styles, 3D, pre-comp and vector pictures.
This sums upward the different return orders based on our experimentation in After Furnishings :
For more technical details, you can become the Adobe Assistance online and come across these manufactures below. I propose that you exam all the information issued in this tutorial or the Adobe Assist to really understand how it works.
I promise you enjoy that article. Feel costless to utilise my Afterward Effects project for your own experimentation. :)
