- "TimeTrimOut" = "(Ctrl+Alt+Shift+O)"
- for azerty keyboard, add "Pad" before numbers ex : 1 -> Pad1

Easy crop comp : select region of interest then composition - crop comp to region of interest
Preserve underlying transparency (small T check) = clipping mask in Photoshop
ctrl + double click pan behind tool = pivot to center

Some expressions

loopOut(type = "continue");
loopOut(type = "cycle", numKeyframes = 2)
loopOut(type = "pingpong", numKeyframes = 2)
loopOut(type = "offset", numKeyframes = 2)

# force fps animation
posterizeTime(8);
value

# round value
Math.round(effect("Slider Control")("Slider")) 
# keep only one decimal
effect("Slider Control")("Slider").value.toFixed(1)

#copy animation from layer and offset time
thisComp.layer(1).position.valueAtTime(time-1)

MAYA / MEL _ flat shaded viewport

edit : Now in Maya 2015 there is an option for that in the viewport -> lighting -> use flat lighting.

I didn't find a simple way to display a flat shaded viewport. So here is a simple script to toggle the viewport with a flat shaded view, usefull to see silouhette when animating. This mel script create a global render layer with a surface shader material override, to change the flat color just modify the surface shader.

// TOGGLE FLAT - using render layer
global proc toggleFlat ()
{
 if (`editRenderLayerGlobals -q -currentRenderLayer` == "defaultRenderLayer")
 { 
  // Check if Render Layer FLat exists or create it
  if (`objExists "RL_FLAT"`)
  {
   editRenderLayerGlobals -currentRenderLayer RL_FLAT;
  }
  else
  {
   createRenderLayer -n "RL_FLAT" -number 1 -makeCurrent -global;

   // SHADER ///
   string $shadName = "SH_FLAT";
   // Check if Shader doesn't exists and create it
   if (!`objExists $shadName`)
   {
    $shader = `shadingNode -n $shadName -asShader surfaceShader`;
    setAttr ($shader + ".outColor") -type double3 0.7 0.7 0.7; 
   } 

   hookShaderOverride("RL_FLAT", "", "SH_FLAT");
   editRenderLayerGlobals -currentRenderLayer RL_FLAT;
  }
  headsUpMessage "FLAT ON";
 }
 else
 {
  editRenderLayerGlobals -currentRenderLayer defaultRenderLayer;
  headsUpMessage "FLAT OFF";
 }
 
}

toggleFlat ();

NUKE / VRAY _ get 3d camera in nuke with vray exr pass

http://polygonspixelsandpaint.tumblr.com/post/40175774250

NUKE _ $gui

- keep subdivision of 3D objects low in GUI, high in render ($gui?10:100)
- keep motion blur sampling low in GUI, high in render ($gui?3:20)
-"$gui" in expressions will return 1 in the UI and 0 at render time. Great for enabling nodes only when rendering on the farm (use it in the disable knob or Switch node).
