Is there a good example on how to use ITextureEditorToolkit::GetTexture();

I’m pretty new to Unreal API programming and my C++ is very rusty. I’m trying to get texture info from the texture editor via a plug-in. Looks like ITextureEditorToolkit::GetTexture() is the best route, but it’s giving me errors when I try to use it. Obviously I’m not using it right. Is there a good example on using this function call?

UTexture *texture = ITextureEditorToolkit::GetTexture(); //doesn't work

I also cannot create an object of class ITextureEditorToolkit because they are abstract classes.

To clarify, what I am trying to do is:
Get the active Texture Editor window
Get the Texture
Get the Texture’s values

Which version are you using?

unreal engine 4.9.2 if that’s what you mean.

You dont really need to access the TextureEditorToolkit to get the Texture.
You can do as follows

When your module is initialized set this delegate to get the TextureEditor

FAssetEditorManager::Get().OnAssetEditorOpened().AddRaw(this, &FMyModule::HandleAssetEditorOpened);

Check if this the asset is a Texture, cast and modifie it as you like

void FMyModule::HandleAssetEditorOpened(UObject* AssetObject)
{
	if (AssetObject->GetClass()->IsChildOf(UTexture2D::StaticClass()))
	{
		if (AssetObject != NULL)
		{
			UTexture2D* Texture = Cast<UTexture2D>(AssetObject);
			Texture->AdjustBrightness = 0;
		}
	}
}

I’ll give that a shot and let you know! Thanks! :slight_smile:

That seems to work! I think it’s enough for me to move forward! Thanks a lot! :slight_smile:

okay, this seams to have stopped working.

	if (Str.Contains(TEXT("brightness"), ESearchCase::CaseSensitive, ESearchDir::FromEnd))
	{
		float testFloat = FCString::Atof(*value);
		UE_LOG(ModuleLog, Warning, TEXT("Setting to %f"), testFloat);
		
		texture->AdjustBrightness = FCString::Atof(*value);
	}

from the output log it looks like its reading in correctly, but the value remains unchanged

The log says:
ModuleLog:Warning: Setting to 0.250000

In the editor, it’s still set to 1 when it should be .25

However, my compression settings do update, so I’m not erroring out and I appear to have the correct texture

This no longer works. pinging again to see if I cannot get a responce
