/*
A BC5 normal map texture visualization shader for RenderDoc.
Usage:
1. Save this to %APPDATA%/qrenderdoc/ on Windows or ~/.local/share/qrenderdoc elsewhere
2. Set Channels mode to Custom in RenderDoc Texture Viewer
3. Select the shader from the dropdown menu

equalent / Qt 5 Dark Fusion Palette
Created February 3, 2020 23:56 — forked from QuantumCD/Qt 5 Dark Fusion Palette
This is a complete (I think) dark color palette for the Qt 5 Fusion theme, as well as a nice style sheet for the tool tips that make them blend better with the rest of the theme. To have immediate effect, be sure to put this in your main function before showing the parent window. Child windows should automatically inherit the palette unless you …
qApp->setStyle(QStyleFactory::create("Fusion"));
QPalette darkPalette;
darkPalette.setColor(QPalette::Window, QColor(53,53,53));
darkPalette.setColor(QPalette::WindowText, Qt::white);
darkPalette.setColor(QPalette::Base, QColor(25,25,25));
darkPalette.setColor(QPalette::AlternateBase, QColor(53,53,53));
darkPalette.setColor(QPalette::ToolTipBase, Qt::white);
darkPalette.setColor(QPalette::ToolTipText, Qt::white);
darkPalette.setColor(QPalette::Text, Qt::white);
