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

**Research **

Thanks for sharing the additional info, helps me lock onto the faster :)

Texture2D and Texture2DDynamic both derive from UTexture, but that is their common base class, so you can't cast a Texture2DDynamic to Texture2D.

Because if you can do that, you can convert Texture2DDynamic -&gt; Texture2D via a UTexture initialization.

I've looked through the 4.15 Engine source code and Texture2DDynamic is used in only a few places, and there doesn't seem to be a conversion to UTexture2D.

The only use of Texture2DDynamic currently appears to be Download image -&gt; Set Brush From Texture 2D dynamic.

Or it can be used with a Texture Parameter in a material shader.


I've figured out how to get the platform data from Texture2DDynamic

You have to use UTexture base class which returns a pointer to a pointer:



```


/**
* Textures that use the derived data cache must override  function and
* provide a pointer to the linked list of platform data.
*/
virtual FTexturePlatformData** GetRunningPlatformData() { return NULL; }


```



For anyone trying  at home make sure to dereference the ptr ptr carefully before trying to even think about access the ptr itself!


```


FTexturePlatformData** PtrPtr = T2D->GetRunningPlatformData();
if(!PtrPtr) return false;
FTexturePlatformData* PlatformDataPtr = *PtrPtr; //Check before dereferencing! ♥ 

//Now check the ptr itself too
if(!PlatformDataPtr)
{
return false;
}

//use the platform data


```



However the is that the platform data for a Texture2DDynamic does not appear to be valid because I guess Texture2DDynamic does not use derived data cache.

**So that means we need to use the FTextureSource itself, I think, to get the byte data.**

But I do not see how to get the byte data from FTextureSource where I will know what the color ordering is to convert to FLinearColor and I am out of  to research .

Anyone want to continue and finish it?

We need a second version of GetPixel data that accepts FTexture2DDyanamic

Is there any plans on getting the Download Image Working with your plugin?
i was told that i can modified that { Download Image } blueprint node with c++ to have it take 2DTexture instead of waiting for the second GetPixel to accepts FTexture2DDyanamic but am not good with C++ :(.

we’ll probably be a piece of cake for you to share so that we can enjoy the plugin in the meantime.

Here’s a image of someone showing me that he got it working But not willing to share :

Thank you.
