VDM Brush Baker v1.0.6

这是一款小型插件，可轻松在 Blender 中创建矢量置换贴图 (VDM) 笔刷。只需单击一下即可烘焙 VDM 并创建笔刷。

界面

位于 3D 视口 ‣ 侧边栏 ‣ 工具。

使用方法

使用“创建雕刻平面”按钮，为雕刻您自己的 VDM 笔刷提供最佳的初始设置。

使用“渲染并创建 VDM 笔刷”按钮，将平面的置换贴图烘焙到新笔刷中。该笔刷将包含所有相关选项，并且矢量置换贴图将以 Open EXR 文件（如果未保存 Blender 文件，则保存在“tmp”文件夹中）的形式保存在 Blender 文件附近。新笔刷可以在雕刻模式下的“绘制笔刷”中找到（雕刻模式下第一个选择的工具）。注意：此插件不会为这些笔刷创建任何预览图像。

提示

雕刻时，请务必遮盖平面的边界以获得更好的效果。 （自动遮罩：网格边界）

使用置换橡皮擦笔刷将顶点移回其原始网格位置。

如果您的 VDM 笔刷在角点处被截断，您可以在笔刷设置的纹理面板中将每个轴的尺寸增加到 1.1 或 1.2。

您无需使用“雕刻平面”作为起点。您可以使用细分度较低的网格，然后自行添加多分辨率修改器。只需确保在细分之前使用“保持角点为边界平滑”选项即可。

注意：烘焙材质依赖于 2 x 2 米（默认尺寸）的网格。

通常情况下，512 像素或更低的 VDM 分辨率就足够了。除非您的雕刻非常精细。

此扩展是 Blender 4.1 捆绑插件的一部分。

This is a small add-on that makes it easy to create vector displacement map (aka VDM) brushes in Blender. A VDM is baked and a brush created in one click.

Interface

Located in 3D Viewport ‣ Sidebar ‣ Tool.

Usage

Use the Create Sculpting Plane button for an optimal starting setup for sculpting your own VDM brush.

Use the Render and Create VDM Brush button to bake the displacement of the plane into a new brush. The brush will be added with all relevant options and a vector displacement map is saved near the blender file as an Open EXR file (or a ‘tmp’ folder if the blender file wasn’t saved). New brushes can be found as Draw brushes in sculpt mode (first tool to select in sculpt mode). Note: The add-on won’t create any preview images for these brushes.

Tips

• While sculpting, make sure to mask the borders of the plane for a better result. (Auto-Masking: Mesh Boundary)

• Use the Displacement Eraser brush to move vertices back to their original grid position.

• If your VDM brush gets cut off at the corners, you can increase the size inside the texture panel of the brush settings to 1.1 or 1.2 for each axis.

• You don't need to use the 'Sculpting Plane' as a starting point. You can use a grid with a lower subdivision and then add a multires modifier yourself. Just make sure to use Keep Corners as Boundary Smooth option before subdividing.

Note: The baking material depends on a grid that is 2 by 2 meters (default size).

• A vdm-resolution of 512 px or lower is usually enough. Unless you have extremely detailed sculptings.
