Blender grease pencil tutorials2/15/2024 ![]() It contains a tree of different curves data-blocks. On the other hand, conceptually a grease pencil data-block is more like a collection. The curves data-block corresponds to a single group of curves, with a set of attributes on curves and points. While they look similar on the surface, with the GP 3.0 design, curves and grease pencil are very different internally (though they do share the same base storage data structure). ![]() This is similar to how both Mesh and Curve geometries can be used in Point nodes (e.g., Points to Volume). The idea is to allow for Grease Pencil geometry to be used directly in any Curve-compatible node (trim, fillet, resample, revert, …). Therefore a Named Layer can work similar to the Named Attribute node. But they may need to be fields (diamond socket).Īlthough layers will be defined in the modifier level, at some points in the workflow (or for advanced use-cases) the option to define a layer inside the node-tree is desirable. Note that in this design Layers are treated as data (circle socket). ![]() That means that layers should be (most of the time) definable in the modifier level as Named Attributes.Ī Layer to Selection node could even allow multiple-input of layers. We also need to make sure that a node-group can be re-used for different Grease Pencil objects. The details are not clear yet, but we will probably need them as a new data-type (socket), as a way to restrict Geometry Nodes operations. Layers are an important element to control the Grease Pencil. We also show Grease Pencil in the Separate Components node in the same order as of the Spreadsheet:
