Access the Scene Graph, craft custom shaders, create advanced object interactions

With AdvancedGraph, you will gain "behind the scene" access to your creations. AdvancedGraph will unleash the true power of the Function Editor, letting you finely control the way your objects or materials interact.


The AdvancedGraph module is an optional module for VUE Pioneer, VUE Esprit 2016 and VUE Studio 2016. It is part of VUE Complete 2016.




The SmartGraph Function Editor

Almost all the parameters in the material editor can be controlled by a function (or set of functions). The function editor is where the true power of material editing lies.

There are hundreds of available nodes to choose from, ranging from numerous types of noises and procedural functions to mathematical nodes, mixers, combiners and filters.

Almost any node can be connected to any other, allowing the creation of highly elaborate materials or special shaders such X-ray, velvet, or cartoon. Reaction to the environment is further enhanced with nodes such as distance to object below or angle of incidence.

You can rename or add comments to any SmartGraph node, in order to improve the readability of your graphs.

E-on developed the SmartGraph technology (inspired by artificial intelligence systems), to help you overcome the sheer number of possibilities presented by the function editor. Thanks to this technology, connecting nodes and creating custom shaders is much more intuitive and fast.




Scene Graph

VUE lets you manipulate the elements of your scene in the standard, straightforward way. With AdvancedGraph, you gain access to a new way of handling your scene that lets you focus on the interactions between the elements of the scene. This is known as the scene graph approach.

Each object, each material in your scene has an associated graph that displays the item's properties as graph outputs. This graph is easily accessed by clicking the graph icon in the World Browser. You can then access any property of any object or material in the scene and use it in the graph to control the outputs of a particular object.

This way, you can define custom relationships between all the objects, terrains and materials of your scene, by visually connecting their properties using a graph of nodes.

This is a powerful concept that lets you create incredibly elaborate scripts to control terrain, material or animation properties based on other items of the scene.

MetaNodes

MetaNodes let you group several nodes or links into a single node, known as a MetaNode. MetaNodes will greatly simplify the readability of your graphs by letting you organize your graph into functional modules.

When you create a MetaNode, you can easily decide which internal parameter needs to be accessible from the top-level. This is known as "publishing". Publishing greatly simplifies the use of MetaNodes by letting you define a simple "interface": expose only those settings that are relevant to the behavior of the MetaNode, and hide away all other "internal" parameters.

You can complete the library of preset MetaNodes that ship with VUE by saving your own MetaNodes for future use.

Custom Interfaces

VUE's powerful parameter publishing feature is now extended to allow the creation of top-level interfaces. Create simplified high-level controls and access these controls directly from the material editor, the terrain editor or the object editors!

You can now reap the power of the function graphs without even opening the Function Editor!

Top-level parameters can be animated via the timeline, including published material parameters. This provides unprecedented control over the animation of your materials.

Top level publishing



Material Control

Sea Level

An additional material mapping option, “Relative to sea”, is now available for material altitudes. With this option you can create materials that appear at certain altitudes, either relative to the sea, or absolute in world coordinates.

An additional input node, “Sea level”, is also directly accessible from the Function Graphs.

The External Dependency nodes of the Function Graph can express object positions and dimensions in user-definable real-world units (meters, feet, etc). This is also the case for other nodes that express real world dimensions, such as Distance to object below, distance from camera, etc.

Also, real world dimensions can now be fed into the Position and Size outputs of the object graphs.

Multi-Materials

Multi-materials let you change in one single operation all the materials of any given object. Multi-materials can be saved for future use. They can also be copy-pasted or drag-dropped between the different objects of your scenes.

Rock Convexity

Rock Convexity

In nature, parts of the rocks that are on the outside will be more exposed to external factors such as weathering. Thanks to the new Rock Convexity node, you can now change the look of the rocks based on their actual geometry, for instance to create dirty insets or polished edges.






Graph-Based Animation Scripts

Using the Scene-Graph approach, you can create complex, graph-based animation scripts to control the properties of your animated objects.

Access each object graph with a click of a button, then build a function to control the properties of the object and connect it to the desired output (e.g. position, orientation, size, etc). Inside the function graph, you can access the properties of other objects in the scene. Using this, it's easy to control your object based on the properties of other objects.

Loose Dynamic Nodes

On top of the easy-to-setup loose forward dynamics introduced in the "loose tracking and linking" section above, VUE features a set of new nodes dedicated to creating naturally flowing animations. This includes delay, integrator, differentiator, PID and constraint nodes.



Advanced Cloud Control

Watch on Youtube!

In order to grant you better control over the shape and look of your clouds, the function graph features outputs that let you control the altitude of the cloud layers (for instance, so that they appear to "go over" certain objects).



Cyclic Noises & Fractals

New cyclic noises and fractals provide powerful capabilities to generate patterns that repeat seamlessly, in space or time (for instance, for that perfectly looping water animation effect)!

You can control the cycle rate along each axis to produce truly amazing patterns.








Texture Projection Mapping Improvements

You can now select the mapping mode for all Projected Texture Maps independently from the general material mapping mode, allowing the creation of very complex materials. This new parameter is also available for the Projected Animation Map node.

For instance, in one single material, you can have a Projected Texture Map for the Color channel set to World Parametric and a second Projected Texture Map used for displacement set to Object Standard.
