TIPS CG

add effect, roughen edges (works only if alpha so if not, copy channel to alpha before)

edit preference of AE, file menu item :

source (in comments)

MinMax effect - sometimes allow to remove black border on mask (ie normal AOV mask)
for better result add a remove color matting Effect just after

install fnord exr update from their website (AE not up to date)
color settings :

Use the effect remove color matting (create an alpha before with shift channel or other if no alpha exist)

Use the "solid composite" effect

use the channel combiner effect with solid alpha checker to unpremult (kind of)

or just a layer style

and set 0 to fill opacity to just have the effect

while pressing quickly it enbale/disable the 2D pan zoom

Now we can't directly acces to all videos of a profile in Vimeo like we could in the past.
We can acces it adding "/videos" to the url to get back this page. As this is a bit tedious to do it manually, we can create a bookmark on the chrome bar and add this function instead of the url :

javascript:(function(){location.href=location.href+("/videos");})();
or
javascript:(function(){location.href+="/videos";})();

selectPref -clickDrag (!`selectPref -q -clickDrag`);
useful for animation in some case to click and drag an object with one click

Useful for adding thickness to animated mesh, add an extrude then edit the component list :
setAttr "polyExtrudeFace4.inputComponents" -type "componentList" 1 "f[*]";

to offset an animation with a node, create a frameCache node, connect an animated channel to its stream channel, and use the past or future values for the offset.
Connection has to be done with scripting :
connectAttr frameCache1.past[14] key.translateY; -> will offset of 14 frames

twist from start :
set attribute on ikHandle like this : twist = roll * -1
for example, roll=150 and twist=-150

Sometimes the Diffuse RE of V-ray is not full flat colors but has some sort of shading/fresnel.
That is normal as it's the Diffuse Filter RE and is affected by reflections. To have full flat colors on compositing do the following :
Diffuse RE divided by the invert of the Reflection Filter RE

Use STMAP node to remap the color of an image with a gradient. set rgb to UV channel in the node.

Sometimes while using motion path, flipping is hard to avoid, here is one solution :
- motion path your main object to the path "path1" blue curve
- duplicate "path1, rename it to "path2", offset it, delete history and edit it to shows the direction pink curve
- create a locator "loc1" and motion path it to the path "path2"
- connect the Uvalue of "path1" to "path2" so they have the same speed
- in the motionpath1 attribute, set follow, object up and in the world up object field enter "loc1"

EDIT : Actually the best method is by far to use a curve on surface as motion path and choose the normal type. To create a curve on surface, first create a surface, then make it live and create a curve on it.

Blocky - mosaic effect in nuke
If someone needed a mosaic filter in nuke, no need to turn to 3rd party plugins, or doing resizes, it's right there. Just have to load it, because it's hidden by default. It's called blocky. You can load it in your custom menu.py, by adding these lines, for example:

nuke.createNode("Blocky")

Sometimes when applying pole vector constraint on a RP IK, the joints move, here is the fix :

"The fix, as it turns out, is really easy. Before you apply the pole vector constraint, you need to place your controller (whatever is going to drive the pole vector) exactly between the start of the IK chain, and the end effector, e.g., the shoulder and the wrist. This is quickly done by selecting the start and end joints, and then the controller, and creating a point constraint (do not maintain offset). Then delete the constraint. Next, use an aim constraint to point the controller directly at the middle joint (say, the elbow). Delete the constraint. Then you just need to move the controller along its pointing axis a little ways, to push it away from the bones. For example, if your aim vector for the constraint was +X, then push your controller a few units forward in its local X axis. Now you can create the pole vector and the joints shouldn’t snap at all."

I had problems to bake camera projection to 2D texture and for any reason Vray texture bake wasn't working properly. Here are the two solution I found :
- Baking the texture (but a bit blurry)
select the mesh and shader then in hypeshade -> edit -> convert to fileTexture (Maya Software)
- Create a texture reference object ( may not work well with animated deformation on mesh)
select the mesh then -> rendering -> texturing -> create texture reference object

To reset perspective camera when it goes away pressing f :
Select an object then : View panel -> View -> Look at selection

Sometime it occurs that one transform node has multiple shape node, to clean it and keep only one shape node :
File -> Optimize scene size -> Deformers

1. Create your motionPath as you normally would

2. Select the "motionPath1" node in you Channel Box inputs and you should see "U Value" and it should be keyframed. Select that attribute and Break Connections to kill the animation. This "U Value" is just like "Parameter" in PointOnCurveInfo nodes in that it will move your connected object along your curve using values 0-1. You think it would be that simple but you will likely get Cycle Check errors.

3. To clean up the setup and avoid errors you can use the connection editor to connect motionPath1 (allCoordinates "xyz") to the translate "xyz" values of whatever object you have attached to your path, and then simply delete the 3 addDoubleLinear nodes that are no longer necessary.

This leaves you with your curve->motionPath->attachedObject and also gives you all the other options that are built into the motionPath node like Follow, Twist, etc. I usually attach locators to motionPaths rather than directly attach objects and also like to use setRange nodes to expand the 0-1 value of "U value" to something more friendly to interact with like 0-10 or 0-100

To procedurally create wave near object :

- create a VRayDistanceTex, a ramp and a shader.

- add object to distTex_set

- set the ramp like below.

- connect VRayDistanceTex.outColorR to ramp.Vcoord

- connect ramp to shader diffuse.

As it's heavy to calculate, it's better to bake it to a texture file map before rendering a long animation.

Sometimes, there is some buggy mesh on which Maya can't apply a planar mapping and when trying to export and import obj to clean the mesh we get this warning :

"Your OBJ file contains faces shared by multiple groups. Maya cannot create multiple objects for this file. A single mesh object will be created instead. The OBJ group information will be captured in Maya sets."

Here is a trick (for multiple objects) :

export to OBJ turning groups and point groups option off then import it in Maya then mesh > separate.

In UV texture editor : polygons > layout and set "Prescale" to "World".

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

- 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).

Annotation node can't have float value, only string. So to display a value in viewport:
- dynamic- particles - particle tools : create one particle
- select particle shape and add a float attribute toto
- particleshape - render attribute - particle render type : numeric
- attribute name : toto
- then connect any value (like scaleX) to toto


//Toggle Isolate Selected in Current Panel
$currentPanel = `getPanel -withFocus`;
$state = `isolateSelect -q -state $currentPanel`;
if ($state == "0")
 {
    enableIsolateSelect $currentPanel 1; 
 }
else
 {
    enableIsolateSelect $currentPanel 0;
 }

// Toggle SHaded WIreframe
string $panel = `getPanel -wf`;
modelEditor -e -wos ( !`modelEditor -q -wos $panel` ) $panel; 

//ToggleOutliner:
if ( `window -exists outlinerPanel1Window` ) 
deleteUI -window outlinerPanel1Window; 
else 
tearOffPanel "Outliner" "outlinerPanel" false;


tearOffPanel "Outliner1" "outlinerPanel" false;
tearOffPanel "Outliner2" "outlinerPanel" false;

For texture map add a Vray texture input gamma attribute

Create a standard gray shader : Vray MTL with gamma correct node in diffuse, 0.5 value color and gamma value 0.455
