RenderTexture.Create

Description

Actually creates the RenderTexture.

RenderTexture constructor does not actually create the hardware texture; by default the texture is created the first time it is set active. Calling Create lets you create it up front. Create does nothing if the texture is already created.

See Also: Release, IsCreated functions.
