Supported RenderTexture format?

Hey,

My game imply the usage of one or two RenderTexture for fullscreen image effect, and I don't really want to use a full ARGB 32bit texture for, say, an alpha mask.

So, what would be the supported RenderTextureFormat by the PS Vita?

http://docs.unity3d.com/Documentation/ScriptReference/RenderTextureFormat.html

 

Well, forget it.

Lazyness is what makes ask dumb question :

Got it with SystemInfo.SupportRenderTextureFormat(). Not that much format supported, only the minimum.

 

It may change with the next Unity-PSM update. The whole things still new'ish remember

 

Any possible date for the next update?

I can't see myself using a full argb32 format for a simple alpha map.

 

Well if you have more than one alpha map, you could get 4 for the price of one (rgba).

 

I'm bumping the topic.

Unity show that ARGB32, ARGB16 and Depth are the only available pixel format for render texture. Are they really the only ones supported? Or does it exists more format in the PSM SDK?
