(39) Rama's Extra Blueprint Nodes for You as a Plugin, No C++ Required!

[ThiloN1987]

GetPixelFromT2D is broken in 4.24. Crash. Access violation.

Do not use this plugin if you're not familiar with C++ and don't want to check the code by yourself before using a node!

I just looked into the UVictoryBPFunctionLibrary::Victory_GetPixelFromT2D function and it

T2D->SRGB = false;
T2D->CompressionSettings = TC_VectorDisplacementmap;

changes the texture settings without letting the user know! The texture will have other settings after calling the node.

When you open the project file with notepad, is the plugin set to 'false'?

Ah, thank you very much, this seems to help! Finally I was able to remove the plugin by setting it to "false" by hand in the project file. Phew! Thank you!

Just a little warning: This plugin does not seem to be fully compatible with the Oculus Quest. I just spent two hours of debugging trying to figure out why my app kept crashing on me ONLY on the Quest, but nowhere else. Turns out it was the usage of the "Append String" (Or "Append multiple"? Can't recall...) function of the VictoryBP Plugin.
Since I replayced it with the builtin "Append" function, everything is working smoothly again.

So I'm working with the Get Sound Wave from File node in 4.24, it creates the USoundWave with the correct duration but no actual audio samples, so there's no sound playing. Same thing happens with the other two nodes (at location and attached). Importing the .ogg file manually, it plays in editor, though this somewhat defeats the point of the nodes. Any ideas?

Hello, I encountered the same problem. Do you have any solutions?

Yeah Sound Importing is broken for me in 4.25 aswell. Tried modifing the code a bit but as I am not very good in c++ so the only thing I could manage is to get some static noise after a week on working on it.

Here's working modified version of that function, add it to your blueprint function library. Check if it works in packaged game.

USoundWave* GetSoundWaveFromFile(const FString& FilePath)
{

#if PLATFORM_PS4
UE_LOG(LogTemp, Error, TEXT("UVictoryBPFunctionLibrary::GetSoundWaveFromFile ~ vorbis-method not supported on PS4. See UVictoryBPFunctionLibrary::fillSoundWaveInfo"));
return nullptr;
#else
USoundWave* sw = NewObject<USoundWave>(USoundWave::StaticClass());

if (!sw)
return NULL;

//* If true the song was successfully loaded
bool loaded = false;

//* loaded song file (binary, encoded)
TArray < uint8 > rawFile;

loaded = FFileHelper::LoadFileToArray(rawFile, FilePath.GetCharArray().GetData());

if (loaded)
{
FByteBulkData* bulkData = &sw->CompressedFormatData.GetFormat(TEXT("OGG"));

bulkData->Lock(LOCK_READ_WRITE);
FMemory::Memcpy(bulkData->Realloc(rawFile.Num()), rawFile.GetData(), rawFile.Num());
bulkData->Unlock();

//loaded = fillSoundWaveInfo(sw, &rawFile) == 0 ? true : false;
FSoundQualityInfo info;
FVorbisAudioInfo vorbis_obj;
if (!vorbis_obj.ReadCompressedInfo(rawFile.GetData(), rawFile.Num(), &info))
{
//Debug("Can't load header");
loaded = false;
}

if (!sw) loaded = false;
sw->SoundGroup = ESoundGroup::SOUNDGROUP_Default;
sw->NumChannels = info.NumChannels;
sw->Duration = info.Duration;
sw->RawPCMDataSize = info.SampleDataSize;
sw->SetSampleRate(info.SampleRate);

sw->RawPCMData = (uint8*)FMemory::Malloc(sw->RawPCMDataSize);
vorbis_obj.ExpandFile(sw->RawPCMData, &info);

loaded = true;
}

if (!loaded)
return NULL;

return sw;
#endif
}

Boldened code is what's different from the original.

Thanks a lot! I can confirm this works now in 4.25 editor and packaged/shipping build!

Hey fine people of the forums!

I use the .wav file loading code to ...well, load .wav files. Works great. I use a UAudioComponent with the resulting USoundWave like so:

AudioComp->SetSound(Sound);
AudioComp->Play(0);

That works like a charm. EXCEPT when I give the Play function a StartTime like so

AudioComp->Play(1.0f);

Now nothing plays anymore. I've tried to chase down the rabbit hole of the Unreal engine code to see what is need for the StartTime to work, but I couln't figure it out. Any help/suggestions are greatly appreciated.

EDIT:

I found my mistake, pretty dumb but I'm leaving it here for completeness:

I did this:

USoundWave* Sound;
Sound->RawData.Lock(LOCK_READ_WRITE);
void* LockedData = Sound->RawData.Realloc(RawData.Num());
FMemory::Memcpy(LockedData, WaveInfo.SampleDataStart, WaveInfo.SampleDataSize);
Sound->RawData.Unlock();

instead of this:

USoundWave* Sound;
Sound->RawData.Lock(LOCK_READ_WRITE);
void* LockedData = Sound->RawData.Realloc(RawData.Num());
FMemory::Memcpy(LockedData, RawData.GetData(), WaveInfo.SampleDataSize);
Sound->RawData.Unlock();

and since 'WaveInfo.SampleDataStart' is null, the RawData in the Sound wave was also then a null pointer. Since the Unreal sound processing on relies on the Sound->RawData, this meant Unreal could not do its thing.
So, totally my stupidity.

Thanks anyway, cheers.

Hello everyone!

First of all:
Rama thank you for sharing this awesome asset for us!

I am using your LoadObjectFromAssetPath BP node, in the editor to load assets into my scene.

I am struggling to get it to load stuff runtime, from a folder that has not been packaged with the game...(Content creator's folder for importing clothes as skeletalmeshes and props as staticmeshes)
Not sure what kind of path can I feed to the node that works with runtime, non-packaged stuff.

Maybe there is another node that I do not know of?

Many thanks
Janos

Hello everyone does anyone happen to seen my post?

[Joaobrasil65]

Hope that the Scene Capture Project functions & CreateTextureRenderTarget2D function are of use to someone.

We've been using CreateTextureRenderTarget2D() for our optical sights and UI related elements for quite some time. It allows us to create texture render targets on the fly and not have to worry about creating them manually in the content browser.

We use Project() for rendering attachment points for our character and items in the customisation UI.

I created a crappy quick mini-map project that uses it as an example.
I'll see about getting it online soon.

Kris.

Do you have any examples of how to implement this for a scope in a dedicated server multiplayer game?

[Kris]

It is not something that would be done on a dedicated server - it would be on the clients.
There are already a number of tutorials/examples floating around showing how to use a scene capture component to render to textures.
A 3d optic is no different to this.

I couldn't figure out how to install this.. First off I had a hard time finding the vertex snapper since I thought that VictoryPlugin25 didn't have the instanced mesh thing for static meshes (didn't find it) then when I try to start up the project with the version of the plugin that has "VictoryEdEngine" which I supposedly need for the static mesh stuff (only thing I need from the plugin) it just gives a bunch of errors when I try to compile..

So..
Does the 4.25 version of the plugin have the 'combine multiple static meshes into an instanced static mesh' stuff? If so, how can I get it to work? I just couldn't figure it out, also I'm tired so that may be a factor in why I couldn't figure this out

Hi there,

I would like to get the save string array to work frame by frame. So that for example i would directly print multiple position metadata of agents per frame into a file.

Hey there,
I wanted to let you know, Rama, that when compiling a game in 4.25, I get some "warnings" for future versions related to your awesome plugin:
