Engraver is a simple addon with set of few tools designed to help carving decals in 3d models. This addon was designed to support modeling with custom normals workflow. I tested many addons which provide much better functionaltiy than my humble Engraver, like Hard Ops, Decal Machine, Carver, etc… but sadly none of them respects custom normals. My work, especially modeling automotive (where perfect shading is a must), for realtime solutions or game asstets, almost always requiers from me to utilize custom normals in order to get both optimized topology and best possible quality. Some of you, who are familiar with tools like Y.A.V.N.E. or Data Transfer modifier for transfering normals, knows that altering geometry using boolean-like tools, almost always results in breaking normal data and destroying the shading of your meshes. For this and for saving time of modeling I decided to develop Engraver.
Engraver works with Blender 2.7* and Blender 2.8.
How to use it:
Simply select your decal geometry, then select your surface geometry on which you want to place it, use ALT+Q shortcut and chose from available tools:
Tools description :
Engrave - Merges predefined geometry of your decal onto selected surface geometry.
Engrave flat (Experimental) - This tool is still under development. It allows to define simple convex or concave decal from flat geometry. Works similar way as Engrave tool but instead of predefined decal geometry you can use flat geometry. After running the tool you can modify it’s bevel by moving mouse and accept it by clicking LMB. After applying bevel width you’re able to define depth of decal the same way as with bevel: mouse movement+LMP for apply.
Cut - Cut a crevice according to border edges of your flat decal geomtery. width ob bevel can be adjsuted by changing depth value under the Settings submenu.
Booleans - Simple boolean tools which maintains custom normal information of your meshes.
Mirror - Mirror model with custom normals.
Here’s comparision of mirroring model with custom normals using standard mirror method and Engraver mirror.
