pls make an example of a blueprint(

As the title states. If you just extract and drop in plugin directory it does not build. Error suggests manual rebuild.

Working with UE4.16, the UE4 editor crashes and closes every time when I run the Example Project.
I can't fix it :-(
Any help is appreciated.

This is part of the output log.

This appears to be an issue with Unreal itself, particularly the use of BlueprintNativeEvent to build the Biome code. I don't want to get rid of the BlueprintNativeEvent tag for DetermineBiome for Blueprint-only users, but at the same time I don't know of a good fix.

In the meantime, the multithreaded heightmap maker uses a polygon-based system and takes biomes directly from the polygon. So far, this has resulted in somewhat better results overall anyway, but the older per-pixel approach still has some merit.

Hello,

I have the same crash after the fix. It always crash on background

I see this error too in foreground

Hello, thanks for the last fix!!

Now i try the new version, this is my blueprint to create heightmap.

But when you change the heightmap generation options to background, it crash with this unknow message:

This is heightmap that plugin produce:

I see in your PolygonalMapHeightmap, you select a method to create each point (EPointSelectionMode). You can't change mode from blueprint, right? I decide to change method and change EPointSelectionMode::InterpolatedWithPolygonBiome to Interpolated and the result is the same the other.

Is heightmap generation is good?

Thanks!

Hey,

this is a really cool Plugin :D

But I have issues at the installation. When I'm trying to start it (after following your instructions) I get this Error: " could not be compiled. Try rebuilding from source manually. "

And when I'm doing this with Visual Studio I get following error message:
...\Plugins\UnrealPolygonalMapGenmaster\Source\PolygonalMapGenerator\Private\PolygonalMapGeneratorPrivatePCH.h" is included by most of the source files. The following source files are not including ...\Plugins\UnrealPolygonalMapGenmaster\Source\PolygonalMapGenerator\Private\PolygonalMapGeneratorPrivatePCH.h" as their first include:...\Intermediate\ProjectFiles\EXEC

I'm using Ue4 Version 4.18 and Visual Studio 17.

Any suggestions??

UPolygonalMapHeightmap::CreateHeightmap takes a long time to complete (5 seconds for a 128x128 array), with the majority of the time caused by interpolating map points.
It would be a lot easier if the heightmap could only be created as needed, and when it is generated it should be done asynchronously if at all possible.
Additionally, the function should be optimized wherever it can be to work out what is causing such a giant bottleneck in performance.

Delanauy has some invalid edges on the side of map (on the border) when using the square points generator.

When i create heightmap with too "high" resolution size ->= 250 for me. I ve got an error and close the editor.

First off: Great plugin.
I tried to use it to generate me a heightmap, but it seems to be crashing nearly everytime at different completion percentages.
I will try to provide as much information as possible.

1. This is how my Level Blueprint is set up.
   

2. This is the trace of the error (happens most often):

Please let me know if you need any more information/help. I tried to debug it myself, but it is quite hard without getting into the whole plugin first.
