    Turning off AA?

    Hi,

    LW10 ( yes I should upgrade to 10.1 but busy :P ) and I need to switch off AA on the render...

    I'm rendering out map tiles for a 2D game, which are perfectly sized and rendered but the renderer is blending them with the background (each tile is rendering out separately) which means lines in the game when I put the tiles together.

    I can scale a bit to overlap the tiles by a pixel but that just seems nasty.

    Any way of turning the AA off or making the alpha channel binary or some other trick?

    Thanks,
    Deano

    Wouldn't you be referring to a render done with "unpremultiply alpha"? The choice is under the output tab in Render Globals.

    Make sure you use a 32bit file format which will save the alpha out with it - 32bit PNG files work nicely.

    AA should be off when using Perspective camera with Classic reconstruction, and no Adaptive Sampling, oversample or Soft Filter. Usually you want to render with a black matte background.

    If there are BG objects or colors tracing, sometimes it is easier to simply drop a black card just behind your FG object and set it's properties to Matte and to not affect tracing.

    Thanks for the help
    unpremultiple alpha and sprite edger are both new to me and very useful!
