Hi, your plugin is great and functions perfectly in most cases.

However, I just encountered some random crashes of the editor. When testing in PIE, sometimes, when mouse over my partly transparent hexagon shape button (using texture, not material), the engine just crashes, but when I restart the engine and test multiple times it does not reoccur, and a few hours later it crashes again. This gives me no confidence, not sure if it will crash in build. If you could kindly take a look if this is something in the code?

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000000000addc3

I noticed that in SCustomShapeButton.cpp around line 179, you did check IsValidIndex, but in my case, exception access violation still triggers.

Does this have anything to do with multiple buttons close to each other and potentially overlap? My hex-shape buttons form a hex grid pattern.

p.s. I just checked the other closed issue and verified:
texture: NoMipmaps
texture group: UI
never stream
compression: vector displacement map RGBA8
and texture size 444*512, power of 2.

Any suggestions?

Thanks,

Hi! I watched the tutorial on how to use your plugin and added it to my project but the widget is not working clicking on it does not do anything at all.. tried debugging with print string too still nothing at all...

Hello, I really really really like your plugin. It is a game changer for me. Can You please somehow add support to version 4.23 because I am working on one project that needs to go to the web and 4.23 is the last version supported for HTML exporting. I was trying to do it my self by updating your code but constantly getting some errors. I am also not good with C++ coding so that is also a reason why.
I thank You in advance and greet You warmly :)

This isn't really an issue but with larger images, if you don't properly set the resolution it can cause issues with touch input.

Here are images that cause this issue.

So i was using the plugin and i had set all the textures correctly with the correct parameters but the engine kept crashing with this error:
[UnrealEditor CustomShape Button!SCustomShape Button::UpdateRawColors_Texture'::2'::<lambda_1>::operator()() [D:\UnrealProjects\CustomShapeButtonSample_UE5-4\Plugins\CustomShapeButton\Source\CustomShapeButton\Private\SCustomShapeButton.cpp:240] UnrealEditor_CustomShapeButton!UE::Core::Private::Function::TFunctionRefCaller<SCustomShapeButton::UpdateRawColors_Texture'::2'::<lambda_1>,void __cdecl(FRHICommandL]

After a lot of testing i have figured out that the problem was that the texture resolution was too high(1080x1080). I have fixed the issue by resizing the texture to 256x256.
I figured i should post this in case someone else had the same issue with this plugin and also because this wasn't mentioned in the documentation.

I'm trying several things here to use this with some materials instead of an image so that I can stitch together button icons at run time instead of modifying every single icon.

So. The button works if I use the hex image.

I then use this same image to try and mask a material:

And then set this as the brush image:

And it doesn't detect any hit testing 😢

I can see that it's this chunk right here relying on a Texture2D but not being able to use a material. https://github.com/JanSeliv/CustomShapeButton/blob/main/Source/CustomShapeButton/Private/SCustomShapeButton.cpp#L157

Any guidance?

Hello, and thanks for the great work!
Bychance, have you tested it with CommonUI?
It feels like having UCommonButtonInternalBase inherit from your class instead of UButton should be enough, and would be a great feature to use!

Hi all,
first of all, I love this plugin, since it does exactly what I was looking for!

I closely followed the tutorial in this video: Custom Shaped Button UE5
Unfortunately, my button does not work as expected. When hovering nothing happens (even though the button should turn red) and only when I hold down the left mouse button and hover the actual hovering state is achieved. Consequently, this leads to not being able to trigger something upon a click event...

My Image has been set to UI, NoMipMaps and VectorDisplacementmap just as shown in the tutorial.

Do you have any idea on how to resolve this issue?
