 render.GetRenderTarget( )

Contents

Description

Returns the currently active render target.

Instead of saving the current render target using this function and restoring to it later, it is generally better practice to use render.PushRenderTarget and render.PopRenderTarget.

Returns

ITexture

The currently active Render Target

Examples

Example

Render something to a different render target, then restore the old render target

local w, h = ScrW(), ScrH()
local customRt = GetRenderTarget( "some_unique_render_target_nameeeee", w, h, true )

render.PushRenderTarget( customRt )
    render.Clear( 0, 0, 255, 255, true ) -- fill the background with blue!

    -- draw all props on the blue background!
    for key, prop in pairs(ents.FindByClass( "prop_physics" )) do
        prop:DrawModel()
    end

    -- save the picture to the garrysmod/data folder.  ~format="jpg" will not work.
    local data = render.Capture({ format = "jpeg", quality = 70, x = 0, y = 0, h = h, w = w })	
    local pictureFile = file.Open( "RenderTargetsAreAwesome.jpg", "wb", "DATA" )	
    pictureFile:Write( data )
    pictureFile:Close()
render.PopRenderTarget()
