    Point Cloud Plugin v0.5.4
    Release Notes

    New Features / Improvements
    • Support for UE 4.22
    Fixes
    • Fixed interference with custom materials using the Volume domain
    • Fixed compilation issues for certain custom materials
    • Fixed compilation issues with certain Unreal Studio materials
    • Fixed incorrect Octree generation for certain point cloud shapes
    • Fixed crashes related to runtime asset re-importing
    • Fixed location precision loss (point banding) when importing clouds with very large offsets
    • Fixed warning messages during project deployment
    NOTE:
    Due to changes made to PointCloudComponent, required for UE 4.22 support, any existing PointCloudActors instance in the scene will most likely require replacing with a new instance, as it's properties will become corrupted.

    Depending on what you want to achieve. Points are rather simple, so you are pretty much limited to colors and location, but yes, you could animate those.

    Yes. This tutorial shows how to modify colors, but you could tweak the position using the exact same approach. Note that this is the CPU-side animation.
    For animations driven by the materials, I would recommend you make a copy of the default material and apply your custom animation elements to it. You would then need to assign it back as a custom material inside the point cloud's settings.

    Is that possible via blueprint? like on your webiste here https://pointcloudplugin.com/tutoria...ng-point-cloud

    Hi Rufson!

    There are two ways to animate points:
    - By persistently modifying the points' data on the CPU side - most flexible, but slow
    - By using custom material expressions (like the one shown on your video) - orders of magnitude faster, but much more limited in functionality

    Is it possible to animate imported (from asset browser) point cloud like in this image? I working on art project where I use BCI brain data and VR and I want to manipulate points using brain wave channel amplitude to achieve smth similar to the image above or like this here: https://www.youtube.com/watch?v=EcbDhAPUWVw

    Hello @phoboz,
    I have a question about animating the point cloud like you showed here (img from your plugin website)

    Hi Phoboz ,

    First of all, fantastic work on this plugin. It was almost "Unreal" how quickly we were able to get up & going, visualising point clouds easily.

    Absolutely terrific work.

    We had one question - when we compile with UE 4.20 (precompiled from Unreal Store), PointCloudPlugin-0.5.3-4.21 only renders into the left eye of our VR headset (we use the SteamVR plugin). The point cloud doesn't render into the right eye at all which obviously creates a deeply disorientating result.

    Do you have any ideas for how we can fix this?

    Thank you and once again congratulations on your outstanding plugin.
    Hi dvt-safesite ,

    Thanks for the feedback!

    First time I heard that happening, I'm afraid.
    - Which headset are you using?
    - Can you replicate the same behavior inside a blank, content-only (non-C++) project with a binary version of the plugin, loading only the point cloud in VR (all other non-default plugins disabled)?
    - See if changing VR Instanced Stereo has any effect (Edit > Project Settings > Rendering > VR)

    To be honest, I'm a little surprised the version for 4.21 even works with 4.20, I would imagine the materials not loading at all.

    Agisoft Photoscan/ now Metashape, or Reality Capture are solid solutions that can already do this competently and at scale.
    Well it is obviously a price. Look at price at reality capture. Also there is big time generating model from picture in RealityCapture and Agisoft/Metashape. I believe in this guy that he is on something new that will bring precision and time in photogammetry with his app that these apps dont have, he had one million, I am waiting for something new I think it is bigger problem to make point cloud from picture and generate model than to menage point cloud (maybe I am wrong)...

    It means, that I do not currently have this feature on the roadmap, but it might be something I will look into at a later stage or if more people request it

    If you mean photogrammetry, then possibly, at some point. However, the immediate roadmap has some other priorities, so it might be a while before I get around to it though
