siggig / proceduralmeshdemos Goto Github PK

Dear Siggi,

Is a runtime mesh (complex) collision building available with your library?

The underlaying RuntimeMeshComponents supports it (in RuntimeMeshCollision.h), yet i did not find an example of this in your demo.

Could you give me some pointers on how this could be implemented (from C++ actor, comparable to "HeightFieldAnimatedActor")?

Do i need to convert and initialise the RMC to a staticmesh first, or can this be circumvented and the collision added directly to the actor?

in unreal 4.24
The project could not be compiled. Would you like to open it in Visual Studio?

[Upgrade]
[Upgrade] Using backward-compatible build settings. The latest version of UE4 sets the following values by default, which may require code changes:
[Upgrade] bLegacyPublicIncludePaths = false => Omits subfolders from public include paths to reduce compiler command line length. (Previously: true).
[Upgrade] ShadowVariableWarningLevel = WarningLevel.Error => Treats shadowed variable warnings as errors. (Previously: WarningLevel.Warning).
[Upgrade] PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs => Set in build.cs files to enables IWYU-style PCH model. See https://docs.unrealengine.com/en-US/Programming/BuildTools/UnrealBuildTool/IWYU/index.html. (Previously: PCHUsageMode.UseSharedPCHs).
[Upgrade] Suppress this message by setting 'DefaultBuildSettings = BuildSettingsVersion.V2;' in ProceduralMeshDemosEditor.Target.cs, and explicitly overriding settings that differ from the new defaults.

The dependencies (RuntimeMeshComponent) changed some functions for 4.20 (fenced with #ifdef's) that need to be brought up 2 date.

I open this issue to let others know, while i try to fix it for me (which may take time depending on how complicated things get..).

Prepare for a PR ;)

Is there any hope to have it compiled for that versions?

For this:

you mentioned:
"Note that this example does not join the meshes where the lines meet at the corners. I'm planning on providing an example for that later on, both in the form of a quick method (rotated cross sections that skew the cylinder) and a more expensive method that looks correct (projecting a circle on a plane defined by the angle where the lines meet)."
can you explain a little bit how to do this? thanks

After upgrading ProceduralMeshDemos and the related plugins to Unreal 4.21, pressing simulate causes hard crash of editor with following error:
Assertion failed: Mesh.VertexFactory->IsInitialized()
Everything has worked great up until 4.21.

Has anyone been successful in getting this to work with 4.21?

OS - Ubuntu 16.04
UE4 - v4.21

Your demo seems very interesting and promising. I have imported your project and tried to open it with UE 4.14.3 on mac, but UE seems complaining about a compilation problem (the following modules are missing or built with a different engine version: UE4Editor-ProceduralMeshDemos.dylib).

I've got a log from UE (which say it can't find module rules files for module 'Procedural Meshes'), and all I get is the 'ProceduralMeshDemos could not be compiled; Try rebuilding from source manually' error popup.
Sorry if the problem is not related on your code, but more on UE (I don't understand why it can't first open the project and then make the dependance and compilation). Since I saw you made some commit with UE new version, I think maybe you could help me. I have just started UE today and I'm not totally sure if projects are totally platform independant or support automatic migration. Thanks in advance

（1）In the UE-Editor, I drag a "SimpleCube_BP" to the level.
（2）I click the "Play" button and run the scene
（3）UE-Editor gets a crash and give a error "0xC0000005: 0xFFFFFFFFFFFFFFFF can not be read!"

Test environment:
UE 4.19
