I have an object called
origin with 272 meshes/faces and
Float Property Layers (called
random_layer), i.e. every mesh has a its own attribute. You can see random values in the Data -> Outliner -> Data API (see screenshot).
Goal: I want to use the values of the
random_layer to manipulate shaders/nodes.
Already tried: To get the values, I tried to use the
Attribute Node calling it with the name
["random_layer"], but with no luck. I tried to wire the the three output nodes, but all seem to output 0.0. Setting the
Vertex Colors) works fine.
The object has a material ('TheOne') using a
Vertex Color node, this is working.
I have searched and found this: Use custom properties (variable values) in the node editor
However, this is not actually using the values of the
Float Property Layers, but rather the graph editor. Also, my values are static and not dynamic.
Any help or pointers are much appreciated.
- Win10 Pro
- Blender 2.81a
- Engine: Cycles (also tried Eevee)
- Add-ons: 'Node Wrangler' and 'Sun Position'
just to clarify how the float layer is created.
mesh_object is an intermediate object for one mesh/cell/face that you see in the screenshot.
random_layer = mesh_object.data.polygon_layers_float.new(name="random_layer") random_layer.data[mesh_object.data.polygons.active].value = random.uniform(0.0, 1.0) bpy.ops.object.mode_set(mode='EDIT') random_layer = bm.faces.layers.float.get(random_layer.name)
Also I am using the experimental 2.82a
