What does RenderTexture.ReleaseTemporary do?

I wondering what the RenderTexture.ReleaseTemporary does?
The scripting AI says "Release a temporary texture allocated with GetTemporary"
https://docs.unity3d.com/ScriptReference/RenderTexture.ReleaseTemporary.html
But I still have no clue what this is talking about.

Thanks.

 

When you create a Rendertexture with gettemporary, releasing it will allow it to be re-used if you happen to need a similar rendertexture in the next couple of frames and if not, it will be destroyed.

The manual is pretty clear, I think, what is it exactly you're unclear about?

 

Unity has an automated object pooling system going on with RenderTextures. GetTemporary and ReleaseTemporary let you tie into this pool.

Google 'Unity object pool' for a more generic description of why object pools are a good idea, and what they are suited for.

 

OK thanks. After re-reading the manuals and looking at some examples I now understand this better.
"Release" must be object-pooling lingo.
