kpprt / SimpleIBMTextToSpeechWS.cs

Last active September 18, 2020 19:59

A simple MonoBehaviour for testing the TextToSpeech service of IBM Watson via Websocket connection. Tested with IBM unity-sdk 4.8.0 and IBM unity-sdk-core 1.2.1. Currently there seems to be no way to determine the final length of the AudioClip while streaming the data. So we use an _estimatedAudioLength that defines the length of our Playback Au…

kpprt / write_makedirs.py

Created October 18, 2019 18:31

Short snippet to create output folders of a Write Node in Nuke.

	import os

	n = nuke.selectedNode()
	if n.Class() != 'Write':
	nuke.message('No Write Node selected')
	else:
	filepath = os.path.dirname(n['file'].evaluate())
	proxypath = os.path.dirname(n['proxy'].evaluate())

	question = 'Yes = create normal file path:\n'

kpprt / CK_Write.tcl

Last active September 1, 2023 08:56

An advanced Write node for Nuke where you can define certain path fragments which are combined to the final path via expressions.

kpprt / CK_AxisBlend.tcl

Last active October 4, 2019 14:07

Blend between two Axis' in Nuke. Caution: The resulting Axis might be skewed while blending even when the sources are not! If there are time offsets on the input Axis' they need to be filled in manually since they are not taken into account automatically.

	set cut_paste_input [stack 0]
	version 10.5 v1
	push $cut_paste_input
	Group {
	name CK_AxisBlend1
	tile_color 0x9c0000ff
	addUserKnob {20 CK_AxisBlend}
	addUserKnob {3 time_offset0 l "time offset 0"}
	addUserKnob {6 hold0 l hold -STARTLINE}
	addUserKnob {26 space l "" -STARTLINE T " \| "}

kpprt / createExrCamVray.py

Created February 26, 2019 16:20

Generate a camera in Nuke from the metadata of an EXR sequence that is rendered with VRay in Maya.

kpprt / CS_CheckerBoard.tcl

Last active February 26, 2019 09:17

A simple checkerboard generator for Nuke that doesn't require a specific format. Instead it takes the input format and overwrites the rgba channels with the checkerboard colors.

	set cut_paste_input [stack 0]
	version 10.5 v7
	push $cut_paste_input
	Group {
	name CS_CheckerBoard1
	addUserKnob {20 CS_CheckerBoard}
	addUserKnob {41 checker_size T Expression1.checker_size}
	addUserKnob {41 centered T Expression1.centered}
	addUserKnob {41 center l "" -STARTLINE T Expression1.center}
	addUserKnob {41 colorA T Expression1.colorA}

kpprt / CS_SequenceViewer.tcl

Last active November 5, 2018 17:29

Shows the current shot side by side with the previous and the next shot in Nuke. Also the previous shot and the next shot are temporally aligned to the current shot.

	set cut_paste_input [stack 0]
	version 10.5 v7
	push 0
	push 0
	push $cut_paste_input

	inputs 3

kpprt / CS_StabilizeCamRotation.tcl

Last active November 1, 2018 17:07

Stabilize an image with the rotation of a 3D camera in Nuke. An additional axis input allows camera animations on top of the stabilization. Options for filtering, overscan and output of motion vectors are available.

	set cut_paste_input [stack 0]
	version 10.5 v7
	push 0
	push $cut_paste_input
	Group {
	inputs 2
	name CS_StabilizeCamRotation1
	tile_color 0x9c0000ff
	addUserKnob {20 CS_StabilizeCamRotation}
	addUserKnob {41 stabilize_frame l "stabilize frame" T FrameHold1.first_frame}

kpprt / CS_Line.tcl

Last active October 8, 2018 15:27

Create a straight line in Nuke from one position to another and define a width as well as rounded or square caps. Since it is realized internally with a Roto node it is also possible to render the line with Motion Blur.

	set cut_paste_input [stack 0]
	version 10.5 v7
	push $cut_paste_input
	Group {
	name CS_Line1
	addUserKnob {20 CS_Line}
	addUserKnob {41 output T Roto1.output}
	addUserKnob {41 cliptype l "clip to" T Roto1.cliptype}
	addUserKnob {26 divider_shape l "@b;Shape"}
	addUserKnob {41 color T Roto1.color}

kpprt / CS_Flicker.tcl

Created April 20, 2018 15:33

Simple Multiply node for Nuke extended with parameters to control a flicker noise.

	set cut_paste_input [stack 0]
	version 10.5 v3
	push $cut_paste_input
	Multiply {
	channels rgb
	value {{"offset + (noise(frame * frequency1, seed) + noise(frame * frequency2, seed)) * 0.5 * amplitude"}}
	name CS_Flicker1
	addUserKnob {20 Flicker}
	addUserKnob {7 frequency1}
	frequency1 0.123
