<p></p> <p><b>新規ページ</b></p><div>=Custom Split Normals=<br /> [[File:CustomNormals_grass_example.png|400px|right|Using custom normals for grass (image by yadoob, thanks).]]<br /> Custom Split Normals is a way to tweak/fake shading by pointing them towards other directions than default, auto-computed ones. It is mostly used in game-dev area, where it allows to counter-balance some issues generated by low-poly objects (the most famous examples are the low-poly trees/bushes/grass/etc., and the 'rounded' corners).<br /> <br /> Blender supports custom normals on a 'smooth fan' base, defined as a set of neighbor face corners sharing a same vertex and 'linked' by smooth edges. This means you can have normals per face corners, per a set of neighbor face corners, or per vertex.<br /> {{clr}}<br /> <br /> ==Enabling Custom Split Normals support==<br /> First of all, to use custom split normals, you have to enable &quot;Auto Smooth&quot; option in the &quot;Normals&quot; panels of Mesh buttons. Please note that once you have custom normals, the angle threshold of the “auto smooth” behavior is disabled - all non-sharp-tagged edges will be considered as smooth, disregarding the angle between their faces.<br /> <br /> ==Creating/Editing Custom Split Normals==<br /> Currently, editing is only possible by using the [[User:Mont29/Foundation/Split_Vertex_Normals/Custom_Split_Normals_Manual/Modifier|NormalEdit modifier]].<br /> <br /> You can also copy normals from another mesh using DataTransfer (operator or modifier).<br /> <br /> ==Importing Custom Split Normals==<br /> Some tools, in particular CAD ones, tends to generate awful ugly geometries when tessellating their objects into meshes (very thin and long triangles, etc.). Auto-computed normals on such geometry often gives bad artifacts, so it is important to be able to import and use the normals as generated by the CAD tool itself.<br /> <br /> There is now the needed helpers in Blender RNA, which allows import scripts to set custom normals from read data. Currently, only FBX importer uses it.</div>
