Material Normalmap Estimated reading: 1 minute 90 views XML<Normalmap fileId="693" bumpDepth="0.3"/><Normalmap fileId="693" bumpDepth="0.3"/> This XML string references another file ID listed in an i3d file. As you’ve probably noticed, the i3d file is an XML document when viewed in a text editor such as Notepad++. There may be variations of this string, such as bumpDepth, which is a simple decimal value that affects the ‘bumpiness’ of a normal map texture used within a material shown on a mesh surface.Note that the normal map’s unique file ID isn’t listed inside GIANTS Editor’s Material Editing Panel.
