Shade

This fixes a bug when creating shaders in the newest version of iOS

- Bug Fixes
- Fixed errors in Screen Size, Volume Flatten and Volume Textures nodes
- Fixed shader error in Noise 3D node when no position input is connected

- Shade Standard is now free (as in beer)
- All standard users have been upgraded to Shade Pro free of charge
- The free trial now unlocks Shade Pro for its duration
- New Example
- Trail Effect
- New Nodes
- Screen Size - The size of the screen :O
- Engine
- Updated to Lua 5.4, improved performance and garbage collection
- GLTF added to supported preview model formats
- Interface
- Gradient editor handles touch interaction more consistently
- Swizzle connections are now easier to drag
- Experimental (Beta features)
- Drag images into the gradient editor to sample colors directly
- Transform - Arbitrary 3D vector transformations
- Time Shift - Shift time for any expression further down the graph
- Function, Input and Output nodes enabling subgraph editing (very experimental)

- Custom Lighting (finally)
- Use Light Params and the new Lighting input to have direct control over all lighting in your shader
- New Example
- Toon Shading (using custom lighting)
- Triplanar (Simplified) (using new Triplanar node)
- New Nodes
- Light Params - for use with custom lighting
- Triplanar - simplified triplanar mapping in one node
- Spherical (replaced Spherical to Cartesian)
- SDF Paint
- Experimental (so much so they have no icons yet)
- Transform UV - experimental sub-network transformation shinanigans
- Buffer / Buffer Source - experimental double-buffered texture wizardry
- Exporter Plugin System
- Support for custom lighting and custom unpack normal methods
- Unity (Surface) plugin
- Added initial support for custom lighting
- Now using UnpackNormal() for normal maps
- ShadeUtility.cs is now bundled with the plugin (but not exported), copy to your Unity project in an Editor subfolder to use
- Graph.json is now exported as well for use with ShadeUtility.cs
- Texture sampling in vertex function now uses tex2Dlod and correct parameters
- Default Unity.shader exported in .shader bundles now matches this plugin
- Plugin now exports folders without .shader extension for improved portability (does not effect ShadeUtility.cs)
- Misc
- The IAP is a once off forever purchase, functionally identical to a full-price app

- Fixed the main menu UI in the library from rendering incorrectly
- Some potential crashes fixed
- Improves usability on Mac

New Examples:
• Simply Sand - Stylised PBR Island Sand Material based on a certain game with animals that cross paths
• Jack-O'-Lantern - Spooky Halloween pumpkin showing off vertex displacement and parallax offset effects

Performance:
• Reduced texture memory consumption by roughly 1/3rd (should help with super-heavy graphs like Forest Floor)
• Reduced node-preview resolution to save memory

Bug Fixes:
• The background input for Tiler nodes no longer rotates when setting random rotation
• Non-pattern inputs for Tiler nodes now use coordinates relative to the Tiler (instead of stamps)

Misc:
• Updated IAP copy to make extra double super sure that users know we do not have subscriptions, just a FREE trial

New Built-In Plugin:
• Map Export, export all texture maps to a folder for use in other tools and apps

Bug Fixes:
• Repeat/Mirror/Clamp sampling options for texture-based nodes now work correctly
• Updated several plugins to export folders instead of bundles
• Added missing mip level parameter for texture2DLod method
• Built-in Unity exporter code generation fix related to gradient nodes
• 8 and 16 bit Grayscale/RGB/RGBA images are now saved to PNG format correctly

Bug fixes for people living on the edge

*** Emergency Hot-fix replacing version 1.2.2 which contained a serious crash bug ***

- Perceptual Gradients
The Gradient node has been updated with more options.
It now blends your colors using a spline through CIELAB color space, rather than linearly through RGB color space.
You can change this with the `Interpolation Mode` and `Perceptual Color Space` settings in the Gradient node options

- Texture Node Update
Adds `Wrap Mode`, `Filter Mode` and mipmap options

- Improved Unity Export (Pro only)

Compare Node

- Compare two inputs using logical operators (less than, equal, and so on). Choose which value to send through based on the result of the comparison

This version of Shade adds support for your mouse or trackpad, plus:

- Updated environment maps to use prefiltered irradiance cube map
- Added environment blur and fade preview options
- Preview camera controls updated to support panning via pinching and trackpad scrolling
- Face AR preview now updates in realtime regardless of shader setup
- Fixed typo in Codea shader evaluator
- Added updated texture property options
- Disabled mipmapping for Gradient node
- Added default texture values for Tiler outputs
- Added missing texture property defaults for baked node outputs
- Removed redundant shader property generation

The Kitchen Sink Update

6 New Nodes

Tiler & Tile Data: Advanced tiling texture generator
Ambient Occlusion: Generate ambient occlusion based on height and normals
Curvature: Generate convexity/concavity from normals for roughness calculations
Parallax Offset: Generate parallax effects to create fake depth
SD Capsule: More raymarching shapes, yay!
