VRAY 3 _tips

Multi tile Uv texture -> just use one filetexture node then in the filename insert <UVTILE> and Vray will change it with the corresponding UV coordonate.
ex : path\color_<UVTILE>.jpg ->  path\color_u1_v1.jpg

MAYA _ nHair

To create nHair from custom curves :
- create guide curve
- select curve then nhair -> assign hair system
- select mesh then nhair -> create hair (optionbox choose the hairsytem)
To display the guidecurve after just uncheck intermediateobject in the attribute editor of their shape

MAYA 2016 _ new / tips

modeling :
holding ctrl Key + moving componenent : move along normal
multicut Tool : holding Ctrl+Shift : 90 degree cut / hloding shift : percent display
edit pivot + clic sur component : snap and align pivot

After creating a polygon primitive, you must activate the Show Manipulator Tool (Hotkey: T) before the In-View Editor appears.

Ctrl + 1 : toggle isolate
Alt + D : deselect

settings/preference :
animation  -> evaluation parralel and check GPU Override (faster for vertex animation/ skin)
display -> material loading Mode -> Parallel to avoid lag at scene opening when lot of shader
color management -> input color space rule : for texture color space, also check in attribute editor for file node to chose individual colorspace

single blendshape deformer:
create blendshape deformer on one mesh then windows - animation editor - blendshape, add new target clic on edit then edit the mesh uncheck edit and repeat to create blendshape directly on mesh.

dR_setActiveTransformAxis 3; // reset current manipulator handle to 3 axis
outlinerEditor -edit -expandAllItems 0 outlinerPanel1; // collapse all in docked outliner

NUKE / PYTHON _ copy text from .txt file and paste into the DAG

create a .txt file containing a nuke group or nodes (copy from nuke and paste as a text) then use this function in nuke to create a node from it

import nuke
from PySide import QtGui

def FromTxtToNukeNode():
 with open ("O:/_WORK/.../textfile.txt", "r") as myfile:
  data=myfile.read() #get the text in the .txt file as a string variable
 QtGui.QApplication.clipboard().setText(data) # set to clipboard
 nuke.nodePaste("%clipboard%") # paste into nuke DAG

NUKE _ rotate normal
