More results. I'm trying to migrate an asset and all its dependencies as tracked by UE4 to another project. There are no Hard References outside of Developers.

I believe this reference was created or copied when copying a Material or Static Mesh from another folder within this same project. So, how can I delete this unneeded Soft Reference so that the migration does not bring across any items outside of the Developers folder? Is there a solid Reference Manager available or in the works? A co-worker thanks Peter! Resetting the Preview Mesh and compiling the material eliminated the Soft Reference. Besides this example, I'm not sure what other items might constitute as Soft References.

It would be nice if Epic would provide such a list. Attachments: Up to 5 attachments including images can be used with a maximum of 5. Answers to this question.

How to delete a Soft Reference?Unreal Engine 4 provides a number of mechanisms to control how an asset is referenced and by extension loaded into memory. You can think of references in two ways: a hard reference where object A refers to object B and causes object B to be loaded when object A is loaded; and a soft reference where object A refers to object B via an indirect mechanism such as the string form of the path to the object.

The first two sections following cover hard references with the remaining sections exploring soft references. For instance, the code below is from the AStrategyBuilding contained in the StrategyGame sample and allows the designer to select which sound is played when a building of a type is constructed.

This property can only be set as part of the default properties for an object the EditDefaultsOnly keyword controls this. The designer creates a new Blueprint class that extends from AStrategyBuilding. Then the sound the designer wants can be saved for that Blueprint. The second type of hard reference you'll encounter is when the programmer knows the exact asset that needs to be loaded for a given property and sets that property as part of the object's construction.

This is done using a special class, ConstructorHelpers, which finds objects and classes for an object during the construction phase. Again from the StrategyGame sample, here's a snippet of the HUD assigning assets that it wants to use as part of its rendering. In the constructor above, the ConstructorHelpers class attempts to find the asset in memory and loads it if not found. Note the full path to the asset is used to specify what to load. If the asset doesn't exist or can't be loaded due to an error, the property will be set to nullptr.

When this happens, the code that tries to access the texture will crash. It's better to assert that the asset loaded correctly if the later code assumes the reference is valid. They function the same way with the only difference being how they are initially set. One consideration about hard references is that as objects are loaded and instantiated the hard referenced assets are loaded too.

Careful consideration needs to happen or your memory footprint can balloon due to many assets being loaded at once. If you want to defer that loading or determine what to load at runtime, then the following sections help with that. One easy way to control when an asset is loaded is to use a TSoftObjectPtr. To the designer, they can work with it just like the direct property reference.

However, instead of a direct pointer reference, the property is stored as a string with template code to enable safe checking of whether the asset has been loaded yet or not. Use the IsPending method to check if the asset is ready to be accessed or not. Note that using TSoftObjectPtr requires you to manually load the asset when you want to use it. The first two methods load the asset synchronously which can cause frame rate spikes, so should only be used if you know it won't affect the gameplay.

The asset is checked to see if the object has been loaded or not. If it has not, a synchronous load happens using the FStreamingManager. This functions the same as referring to a specific asset, but instead refers to the UClass for the asset instead of an instance.Suppose that the garbage collector determines at a certain point in time that an object is softly reachable.

At that time it may choose to clear atomically all soft references to that object and all soft references to any other softly-reachable objects from which that object is reachable through a chain of strong references. At the same time or at some later time it will enqueue those newly-cleared soft references that are registered with reference queues.

All soft references to softly-reachable objects are guaranteed to have been cleared before the virtual machine throws an OutOfMemoryError. Otherwise no constraints are placed upon the time at which a soft reference will be cleared or the order in which a set of such references to different objects will be cleared. Virtual machine implementations are, however, encouraged to bias against clearing recently-created or recently-used soft references. Direct instances of this class may be used to implement simple caches; this class or derived subclasses may also be used in larger data structures to implement more sophisticated caches.

As long as the referent of a soft reference is strongly reachable, that is, is actually in use, the soft reference will not be cleared. Thus a sophisticated cache can, for example, prevent its most recently used entries from being discarded by keeping strong referents to those entries, leaving the remaining entries to be discarded at the discretion of the garbage collector.

We still have the data, and as mentioned above, we will work to migrate the top content into various official resources. We are still exploring how we may be able to export the Wiki data to the community members who are looking to stand up a centralized, community-hosted Wiki, to help expedite their efforts.

Thanks so much to those that are coordinating the initiative and have reached out!

I know that the wiki wasn't optimal, but there were many wiki pages developers like me had bookmarked for years beacuse they contained comprehensive and easy information, which is now missing. Why not just keep the wiki read-only online?

Just to retain the old pages? I'm pretty lost right now without some of these articles and I don't understand why the only option you had was to completely disable it.

Please think about opening it up again just for read. I don't care about the maintenance mode, but the wiki was an important learning point, which is now gone. Hobby game developer from Germany Follow me on Twitter! Comment Post Cancel. Why take the wiki down before duplicating the information in other areas? Aside from the fact that scattered resources like forums, blogs and even UDN are nice as supplemental and no replacement for a community updated repository.The API reference is an early work in progress, and some information may be missing or out of date.

It serves mainly as a low level index of Engine classes and functions. For tutorials, walkthroughs and detailed guides to programming with Unreal, please see the Unreal Engine Programming home on the web.

EngineSettings Encapsulation of engine setting objects.Ever since I first wrote about creating object outlines in Unreal Engine 4 I have wondered if it was possible to render them as soft outlines instead of harsh binary lines. Overall it came to be too costly to come with a decent solution and so I stuck with the binary outlines you may have been in several of my earlier posts.

Looks pretty decent, right? The effect is more expensive than the binary outlines since we perform several blur steps in the SpiralBlur-node to get to look decently smooth. Without going the custom engine route there is no way to downsample the post-process step where we sample and blur the information from the Custom Depth buffer.

Later in this post I will talk about performance of the effect itself. The built-in implementation takes the scene textures and over several iterations creates….

The default settings are at about iterations, which is pretty heavy! The node graph for it is reasonably simple and most of the logic happens inside the custom node which I added as a code sample below.

You will want to keep the DistanceSteps and RadialSteps as low as possible while maintaining a smooth edge. To conclude, the answer is yes! I imagine there may be more efficient ways of blurring the custom depth buffer to get similar results, I simply leveraged the available shader code to quickly get to a proof of concept.

Hi Tom,thank you for this effect. May I ask you to answer this issue? Cesar, did you manage to solve this? Hope that helps. I can achieve this using your other outline setup, by just adding a oneminus after the Determine Occlusion set of nodes, and then multiplying that just before the lerp input, that worked great for that. I see this is already occluding against the mesh that has Custom depth switched on. This really was just a proof of concept on the softness of the outline.

The current material has compilation errors, so it will not render correctly in feature level SM5. Are you sure you wish to continue? Looks like you may not have specified any inputs in the node itself see SpiralBlur in the engine on how that works. Seems that its complaining for the UV property is not connected, although you do not have it in the image either, so, there must be something I am doing wrong.

Click on the main node in your material to access the properties and change it to be a Post Process. This will expose ONLY the emissive channel. If I remove that duplicate line from the code that goes in the custom node I get a bunch of other errors about missing declarations and not found Intrinsic functions.

I tried this out in both 4. Any way you could either send me a copy of the function or help me get it working?A struct that contains a string reference to an object, either a top level asset or a subobject. This can be used to make soft references to assets that are loaded on demand.
