Unexpected behavior for td.twirl shader

    Nov 27 2011 | 2:25 am
    I've used other tx-class shaders successfully, but tx.twirl is baffling me (in both Max 5 and 6 on Mac). I thought it wasn't working at all.... just fills the window with a solid color. I've now found that occasionally a source image will allow me to see a spiral... but it's basically monochrome and lacks any detail of the source image. It's like it's just grabbing a small block of source pixels and twirling them, rather than the classic twirled full image like in Photoshop and other systems. Any information is appreciated!

      thanks for the report. i can reproduce, and we'll try and figure out what's going wrong here.

      It's because the texture coordinates used go from [0, 1] and not [0, dim]. I've fixed this for the next release.
