[Denny]

Awesome! Keep up the great work.

Update to v1.4.3
Fixed a bug that failed to create a package
From UE4.24, editor-only modules must be set to UncookedOnly...

Update to v1.4.4
Fixed a bug that failed to build plugin when using MacOS.

[pafuhana1213]

Hi guys,

Update to v1.4.5
Changed Gravity to work with Component Space.

Update to v1.4.6
Fixed a bug that crashes when the same bone as Root is specified as ExcludeBone.
Added the process of displaying Warning or Error on a node in case of an invalid setting.
Technical Description: http://pafuhana1213.hatenablog.com/e...0/05/16/173837

Update to v1.5.0
Added the BoneForwardAxis property to set the orientation of the bone. This only affects the behavior of DummyBone.

Update tov1.5.1
Fixed a bug that the display position of debug display by bEnableDebugBoneLengthRate was misaligned.
↑Change the text format of the debug display to the same as the engine standard bone name display

Update to v1.5.2
Fixed a bug in v1.5.1 that did not take DummyBone into account.

And, I've uploaded the zip files for the 4.24 and 4.25

I've created adoption page.

I'm really happy that my plugins have already been adopted by some great games!
If you're using my plugin in your work, I'd be happy if you let me know about it

Hi pafuhana1213,

I found this plug-in half a year ago, after integrating it into my project, it solved nearly all of my problems regarding physic simulation while traversing at high speed. I wrote a blog post about this, and I hope you enjoy reading it.

Here is a BIG THANK YOU for your effort! :3

Wow, amazing work. I'm stunned this is free. Would this work with ragdoll physics?

[pafuhana1213]

Update to v.1.5.3
- Fixed a bug that prevented parameter adjustments with curves from working properly when the BoneIndex of Mesh and Skeleton were different.

Update to v.1.6.0
- Added the ability to manage collision settings with a dedicated DataAsset. This allows sharing of collision settings between multiple nodes.

And...sorry for my late reply...

Hi rit,
Thank you for your using and writing a great blog post!
I'm very happy to help you!

Hi muchogrande,
Unfortunately, it's not useful as a ragdoll.
This plugin is completely within SkeletalMeshComponent, so it can't recognize external floors and walls, etc.
Maybe...you can do something ragdoll-like with PlanaerLimtis but I just don't recommend it.

[pafuhana1213]

oh sorry I misunderstood,
I have not tried this plugin in conjunction with the ragdoll (PhysicsAsset). Probably PhysicsAsset takes precedence over the PhysicsAsset control, so it should be important to decide which bones to apply PhysicsAsset to!

[muchogrande]

Thanks, yes I did some tests and it appears that PA takes precedence. So as long as you have a good PA the transition from Kawaii to ragdoll works (in theory, I have yet to do a detailed practical application!) Thanks for continuing work on this excellent system!

Hi pafuhana1213,
playing around with the plugin, i noticed an error when trying to launch a packaged .exe (UE4 version is 4.25). It says:

"Plugin 'KawaiiPhysics' failed to load because module 'KawaiiPhysics' could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project."

Starting the standalone in editor is fine, so the plugin is working. Is there any way to work around this problem? Help would be greatly appreciated.

Did you make sure to have the plugin in your project's plugin folder (not engine's) before compiling?

[sprenghuhn]

Yes, it's there. Curiously, once the plugin was activated, its project is packaging but does not run. If it is deactivated, it reports a packaging error (something with missing Visual Studio 17).

[pafuhana1213]

umm... Would please share with me how to reproduce it in UE4.25.3?

[sprenghuhn]

I'm using 4.25.3 (freshly installed) and Kawaii version 20200904-v1.6.1. The plugin is correctly installed and working, as long as i mount a project in editor. Packaging to WIN64 is also fine. However, when i am running the exe, it returns the above mentioned error (Plugin-Module not found). I checked via non-pak-packaging that the plugin is in the WindowsnoEditor-Folder.
Now, when disabling the plugin, packaging returns an error. Below is the part of the output-log concerning Kawaii:

BTW, the error message regarding an missing Visual C++ installation is also occuring with certain other plugins, e.g. PhythonEditorScriptPlugin

This sounds to me like the error mentioned in the release post for UE4.25


This was mentioned there by an user:

I try to package my marketplace plugin with 4.25.3 and I have this error:

I have VS community 2019 v16.6.5 and the build worked with 4.25.0

Also, why there is -2017 in UnrealBuildTool arguments? Do you need VS 2017 now?

And someone answered

no console out there except pc even supports VS2019. I don't understand why everyone thinks they need VS2019.... NO you don't need it you need 2017.

But looks like he found a solution:

Found! VS2017 is now REQUIRED to build a plugin with RunUAT BuildPlugin command. You can override it by adding -VS2019 after BuildPlugin. It was added in 4.25.3

Not entirely sure is this, but it looks like that... sort of.

What I can confirm tho is that I recently compiled a game in 4.25.3 using the 1.5.3 version of Kawaii without a problem.
