Houdini to Substance Painter Workflow for Heightfield Terrains!

Here I demonstrate how to export a simple heightfield from Houdini and import it into Substance Painter. We generate mask images using all the fancy Heightfield information we get from the erosion node like the Cliffs, water, debri, and so on. Then we use these mask images and plug them into the Substance Painter to setup materials for shading.

Houdini到Heightfield地形的物质画家工作流程!

在这里,我演示了如何从Houdini中导出一个简单的高度场并将其导入到Substance Painter中。我们使用从腐蚀节点(如悬崖,水,碎片等)获得的所有奇特的Heightfield信息生成蒙版图像。然后,我们使用这些蒙版图像并将其插入到Substance Painter中以设置要着色的材质。
