Full dynamic one-click solution for material blending of objects

in Blender 2.83+ (2.90, 2.91, 2.92)

Main features:

• Easily create material blend of selected objects with active
• Non-destructive operations: create, apply, remove material blends
• Option of executing the operations for all blends of source object
• Real time dynamic blends works in viewport, Eevee and Cycles
• Option automatic create material from blended objects
• Option to Blend Normals of objects
• Easily tweak individual blend of object
• Easy tweaking of all blends of source object
• Preserve texture scale from source object with mapping options:

1. World space: Geometry node – Position output

2. Object space: Texture Coordinate node – Object output

3. UV v1: Texture Coordinate node – UV output + Blendit Transfer UV

4. UV v2: UV Map node + Blendit Transfer UV

Note that for the version 1.3 there are many limitations, restrictions and some bugs.

I plan to figure out most of it in new versions.

Limitations:

• Only one blend per object supported
• Two source objects can’t be blended together
• The add-on only works with the first material slot
• You shouldn’t rename Blend materials for proper functionality
• You shouldn’t remove original materials for proper functionality
• You shouldn’t rename Blendit modifiers for proper functionality
• The quality of the blend depends on mesh density
• Only an UV map with Active Render can be transferred
• Multi-user material doesn’t support different blend source objects
• Auto Smooth turns on when Blend Normals is used
• You must use UV mapping and Transfer UV to blend Normal maps
• Used simple inaccurate blending of normal maps
• Automatic connected Displacement and Volume outputs aren’t supported
• Limited support for input nodes depending on the source object
• Mappings inside node groups are not affected
• Blender 2.90+ bug, crash when switching to UV Edit of source object
• Blender 2.90+ bug, crash when switching to Edit Mode of source object

Changelog:

Blendit v1.1

• Implemented full support of Frame Nodes
• Fixed issue with Reroute Node and full support of these nodes
• Fixed issues caused by incompatibility with other add-ons affect material nodes

Blendit v1.2

• Automatic linking of unconnected node mapping input
• Basic warning if unsupported mapping is used
• Basic warning if unsupported nodes are used
• Fixed blended material doesn’t work in Cycles
• Fixed transfer of active UV Map instead of UV Map with Active Render

Blendit v1.3

• Full support of material nodes (ColorRamp, RGB Curve, Vector Curves)
• Small performance improvement through better modifiers settings
• Auto Smooth option added to Settings (recommended to turn-off in Cycles)
• Added switches for Simple and Advanced blend modes
• Advanced mode – added option to tweak the minimum blend distance
• Advanced mode – added option to tweak the gradient of the material blend
• Advanced mode – added option to tweak the blend of normals
• Fixed issue and added warning if objects have no materials
• Fixed Transfer UV doesn’t have ideal mapping when Blend Normals disabled
• Fixed Auto smooth did not return when blend was removed
• Fixed UV Map node could have non-existent UVs assigned
• Fixed applied blend shows sliders without influence

Planned features for next versions:

• Show/hide blend switcher
• Tweak multiple normal blends of objects at once
• Option to create a unique material per object
• Option stack and handle multiple blends on objects
• Operations for individual blends in the stack
• Supported blend according to height maps
• Accurate blending of normal maps
• Option to use template materials
• Option to deform geometry at the intersection
• Supported blend with multiple material slots
• Support for different blend sources for multi-user material
• Supported automatically connected Displacement output
• Supported automatically connected Volume output
• Supported transfer of multiple UV
• And more…
