    1. Integration Tutorial:




    Getting Started:

    1. Configuration Settings:
    • MeshResolution: Controls the number of LoS points (vertices) per degree of the arc.
    • EdgeCaseSubdivisionCount: Controls the precision of the edge detection operations. Higher values increase the likelihood of detecting multiple edges.
    • EdgeDetectionIterations: Controls the accuracy of the edge detection operations.

      When I see this I think of those cool dynamic hard shadows from FEAR and Doom3

      Could this be used as a base for a shadow system like that? Would it be any more or less performant than UE4's built in dynamic light system?

        As a fan of the original F.E.A.R. growing up, it would have been really awesome if that were the case. But this system is using a procedural mesh driven approach instead of lighting models, with a focus on the performance benefits brought about by edge detection over brute force approaches. So I don't imagine it being of much use as an alternative to lighting systems in FPS & TPS games.

            Hi, I just tested out the visualization on the new v4.22 edition of Unreal Engine & everything seems to be working fine. You can go ahead and download the v4.22 files from the launcher now.

            If you're upgrading your project from 4.21 to 4.22, it should run smoothly without having to make any changes. If anyone's having trouble with the process, feel free to contact me.

            Also, LoS Visualization is now 20% off as part of the UE4 Spring Sale.

                Hello, I've integrated this into the twin stick shooter example project but the pawn (spaceship) is a static mesh, is there any reason why that would cause this to not work? Setup was really easy and straightforward, so I'm confused why I don't see it working. I did the optional setup in construction script so I could preview it but even that isn't working. Using engine version 4.22.1

                  Hi, I'm assuming that you sent me a mail yesterday regarding the same issue. I was able to replicate the issue at my end and have sent you the solution, but I'll share it here for others who might have run into the same problem.

                  The v1.1 update had added 360-degree rotational freedom for the visualization system (so that you could use it not just in top-down, but also in other cases like sidescrollers). As part of this feature, a new output parameter 'Up Vector' was introduced in Step 4 of the integration tutorial. The above issue can be solved by connecting a 'Get Actor Up Vector' node to the new output parameter as shown below:

                    Does this use UProceduralMeshComponent? I ask because when building out a similar system to this in the past which used UProceduralMeshComponent and ran into a problem where if you we're constantly moving, and updating the component, the component's collisions did not bake on the same frame that the updates were made (but were disposed of earlier). The problem with this was that while moving you were unable to gather any collision data which you might use for things like what actors can this user actually "see" and render/hide them accordingly.

                    Even if UProceduralMeshComponent is uses does that issue exist in your system, because if not I'd consider just buying it to solve that problem rather than hitting my head against a wall anymore (that and the ray-trace edge detection optimizations do sound nice!).

                      Hi, I'm using the Procedural Mesh Component as well, but its collision has been turned off since obstacle detection is handled through ray traces. So it might not be of much help to you in this scenario. But I did run into a similar issue as yours when it came to updating the mesh itself. There was a slight lag in the procedural mesh vertex updates, but this was solved by setting the update tick group to PostUpdateWork (https://docs.unrealengine.com/en-US/...tml#tickgroups).

                      So I'd say that changing the tick group might be worth a try in your case as well. If you're lucky, that could solve your collision lag. Just make sure to do so for both the component as well as its owning actor.

                      Also, on a side note, if you have a lot of vertices that get updated every frame, I'm not sure how efficient it would be use the collision on proc mesh component. Using normal line traces to detect actors around you might be less taxing on the processor.

                            Hi, the base price after discount is 10.49 USD. You might see additional charges based on tax laws in your country.

                            Regardless, what you see on opening the link is the real version, if that's what you were asking about.

                              Can it be used in third person shooters?
