Mesh Viewer

• Matrix-> Matrix In

Functionality

Similar to (Viz-> Viewer Draw) but instead of using OpenGL calls to display geometry this Node writes or updates Blender Meshes on every geometry update. The bonus is that this geometry is renderable without an extra bake step. We can use Blender’s Modifier stack to affect the mesh. The only exception to the modifiers is the Skin Modifier but we aren’t entirely sure why, maybe because BMview invalidates the BMesh between updates.

Note: The performance of the node can be increased significantly by putting vertices in numpy.float32 format in case if topology of the mesh remains unchanged.

Parameters & Features

Param	Description
Live	Processing only happens if update is ticked
Show/Hide objects in viewport	Hides current meshes from view
Make objects selectable	Disables the ability to select these meshes
Show/Hide objects for render	Disables the renderability of these meshes
Mesh Name	Base name for Objects and Meshes made by this node
Random name generator	Generates random name with random letters
Select generated objects	Select every object in 3dview that was created by this Node
Collection’s name	Pick collection where to put objects
Material	Assign materials to Objects made by this node
Create new material	It creates new material and assigns to generated objects
Origin	If it disabled then origins of generated objects can be set manually in viewport
Merge	On by default, join all meshes produced by incoming geometry into one
Show edges	Show edges in viewport
Apply matrices to	Matrix can be assigned either to objects or mesh. It will effect only onto position of origin. Also if matrix is applying to objects lock origin will be always True
Fast mesh update	It tries to update mesh in fast way. It can not update mesh at all in some conner cases. So it should be disabled
Smooth shade	Automatically sets shade type to smooth when ticked. Generator-> Sphere
To 3D panel	Show the properties in 3D panel Generator-> IcoSphere

Note: Some features are placed in the `N-Panel` / `Properties Panel`.

Outputs

• Objects

3D panel

The node can show its properties on 3D panel. For this parameter Show in 3D panel should be enabled. After that you can press scan for props button on 3D panel for showing the node properties on 3D panel.
