If you'd ever dreamt of dealing with hair and fur like with common polygonal geometry with absolutely no limitations, then MeshPaint is a dream that came true. The following pictures show our new benchmark for the hair and fur quality, with the details included bellow. The scene, accompanied by a full-blown tutorial is shipped with the product.

Platform: LW7.5, Win2000
Hardware:P4 1.6GHz, 512mb ram


System Overview

The main modeling tool provides many different workflow styles that are either active and allow to place new geometry using the mouse on an underlying base-surface, or automated - these consider an additional guide layer in order to substitute mouse-clicks and provide interactive post-edit modifications.

The MeshPaint system utilizes textures, envelopes, and plenty of custom-built gradients for each parameter, the fundamental transformations per instance, and probability-based mesh creation. The basic elements, crucial in the modeling process, such as points, lines, and curves are fully supported all the way across the board.





The MeshPaint package also includes several additional modeling tools such as Curve Tool for convenient curve styling, and Clone UV Tool for handling uv mapping of cloned instances.


MeshPaint Work-Flow Videos

The following section previews MeshPaint's key features and the various different work-flow styles.

  • Mouse Clone stands for the basic active modeling approach, cloning custom layers over the base layer. This mode can be described as "model by painting", hence the name MeshPaint.


    Feature: basic mouse-cloning, clone-layer settings, various parameters of the mouse spray, the minimum spacing feature, the edge gradient.

    Feature: advanced mouse cloning, custom mouse-button gradients instancing a different clone-layer with each mouse button, texture-based geometry cloning.

  • Points represents one of the automated modes. Instead of mouse-clicks, an additional guide layer including just points defines the areas where new geometry will be added.


    Feature: basic mouse-cloning, clone-layer settings, mouse spray sensitivity, the minimum spacing feature, application of the edge-distance gradient.

  • Mouse Selection offers the surface-aligned cloning for even the most fundamental modeling tasks. For instance, one can create a basic skeleton either from curves, lines, or polygons, and model the actual object by placing polygonal patches onto this skeleton. Another use may be an object's mesh redesign, such as low-poly from high-poly object creation. In this case, the user clones selected points over the base-surface and applies either custom or LW-native construction tools such as AddPoly to create polygons.


    Feature: The "skeletal patching" approach in action. All kinds of objects, both organic and mechanic, can be created this way.

  • Curve Create: similarly to the Points mode, curves in an additional guide-layer define areas on the base surface, where new geometry will be created. This time, the clone-layer includes a single fiber profile that will be extruded along each curve found in the guide-layer.


    Feature: fast and easy conversion of curves into polygonal geometry, basic styling with the Curve Tool.

  • Curve Deform: unlike curve-based extrusions of the Curve Create, this mode performs curve-based deformations of the clone-layer along each curve found in the guide layer. Moreover, MeshPaint in all of its modes generates an additional weight-map filled with the inherit surface parameter. This way, the weight of the base-layer can be transformed into clones, and utilized later, i.e. in the shading process.


    Feature: Automatic Clone mode, Curve Tool, the inherit surface feature, transferring the base layer's weight into clones, then applying a gradient to modify the outgoing vmap.

  • Curve Tool: serves a general curve-editing purpose. This solution offers plenty of various styling features; with each parameter texturizable, the system provides great control.


    Feature: a wide array of the Curve Tool parameters, ranging from the basics such as stretch, and drag, to the more advanced; curl, kink, smooth, textures and global falloff.

  • Clone UV: handles the uv mapping of the cloned geometry. Although the output can be shaded in many different ways, an uv-map can always come in handy, i.e. when selecting a particular clone in dense population.


    Feature: various clustering techniques applied by CloneUV Tool when handling UVs of the instanced geometry.
