  odd viewport behaviour w/continuously rasterise on

  Posted by Jimmy Brunger on November 10, 2011 at 4:19 pm

  Hoping someone else might have had this problem in the past….

  Built a basic map using masks and various colour overlays, bevels, etc which I want to move around and fly close into with camera. each country border is a sep mask all on the same solid layer. I have an expression on each mask (below) so I can change the gap between each country with a slider in the parent comp depending on how far I am zoomed into map. Also a similar expression used to control bevel so that it looks right at diff magnifications…

  NOW, I need the CR button checked so map doesn’t go soft when zoomed in close, but when this switch is on my comp behaves very strangely….if I move the camera at all or set any camera keyframes nothing is updated in viewport/comp window. However if I then RAM preview the same couple of KFs it shows me my camera move. Purge cache and then tap through and it shows me the movement, but when I actually physically move the camera or type any new values in I don’t get an update….

  CR button switched off and my comp behaves as you’d expect, albeit VERY soft and pixellated.

  NOTE: This is only a problem when using the camera – if I scale, position or rotate the comp it works fine..but obviously not ideal for animation of a scene.

  Any ideas guys!?

  Thanks for any help you can offer,
  Jim.

  comp("PARENT COMP").layer("Control").effect("Mask expansions")("Slider")

  value+comp("PARENT COMP").layer("Control").effect("Bevel")("Slider")
