Point Cloud Plugin

Wonderful! That’s what I was hoping for.
I’m still pretty amazed by how performant it is nowadays. You’ve done a great job.

Engine Crashes in RenderCore Module with 4.22 Version!

Hi there and thanks for the report. Few questions to help me find the issue:

• Which plugin version are you using?
• How to replicate the crash? (the more accurate the steps, the better)
• Can this be replicated in a brand new project or is related to an existing one only?
• If possible, please send me the log files from the crash via private message.

Thanks again for this plugin - could I ask any news on when you’re implementing e57 support? Would be super useful for us.
Thanks!

Hi ,

Thanks for the feedback.
No concrete timeline at the moment, but planning to have it ready sometime Q4 - stay tuned!

P.S. Did we meet at the Unreal Event in London? I’m sure I recognize the name!

[david.gillespie]

Thanks for the update. We are definitely interested in e57 as its lighter weight than xyz and Rhino can also open it meaning we don’t have to have the same data in multiple platform specific formats. Looking forward to when it gets added.

Yes - was at the summit on Thursday. Was the geeky one who kept asking lots of questions!

We support LAS at the moment if that helps you in any way.

[david.gillespie]

Thanks, I’ll check that format out too

@Janitorus

Dynamic shadows do not always behave as expected and appear to be cut off. Moving them around does not fix them, cut off stays the same. Any idea?

Love the plugin though!

@ax448

Hey @ , did you get some files from Janitorus to help you look at the issue?
Because I’ve got it popping up on a couple large pointclouds I’ve tried. (Only tried with directional-light.) but at a lot of angles the shadowcasting just stops working.
(Setting the directional light at an angle, and spinning it around a mesh clockwise leaves it only working for maybe ~1/3rd of the angles, for example.)

Sometimes it’ll work fine when it’s just basically top-down, almost. It’s rather strange. A lower-angled directional light only seems to work from some directions.

Is this part of the same issue? ( 4.22. And tried in a completely new/clean project as well. ) I also noticed the same kind of strange cutoff from spotlights as Janitorus.

Happy to report the issues should now be fixed!

That’s awesome, thanks for looking into this! What was causing it?

Shame to admit, but my math failed me

I’m currently trying to package a project (Windows 64bit) but get the error below:

UATHelper: Packaging (Windows (64-bit)): ERROR: Missing precompiled manifest for ‘PointCloudRuntime’. This module was most likely not flagged for being included in a precompiled build - set ‘PrecompileForTargets = PrecompileTargetsType.Any;’ in PointCloudRuntime.build.cs to override.
PackagingResults: Error: Missing precompiled manifest for ‘PointCloudRuntime’. This module was most likely not flagged for being included in a precompiled build - set ‘PrecompileForTargets = PrecompileTargetsType.Any;’ in PointCloudRuntime.build.cs to override.

However I cannot find “PrecompileForTargets” and I’m not sure how to code that into that file anyway.

Hi @anonymous_user_e1a3f948

I’m assuming you have copied the plugin into the Engine/Plugins folder, if so, that is what causes the issue. For now, the plugin has been designed as project-level - copy it into MyProject/Plugins/PointCloudPlugin instead.

[anonymous_user_e1a3f948]

Thanks @, that fixed it!

Been working with the latest release today - really really like it! Love the editing features and collision mesh, so easy to set up. Thank you for your hard work developing this, it’s a fabulous tool.

[DeusUpperX]

Hello, I am able to successfully use the point cloud plugin the editor. It is also able to be packaged however when the packaged game tries to access the point clouds it crashes immediately. Anyone have any ideas or potential solutions? Thanks.

Hi @DeusUpperX

Sorry for the late reply - holidays

Are you still using a v0.5 branch of the plugin? It sounds like an issue that has been fixed for v0.6 - I recommend you update it and let me know if this solves your problem.

[DeusUpperX]

@

No worries and actually yes it was fixed actually after updating the plugin from v0.6 to v0.7. Thanks.
