+**How To Import A 3DS Model** by Panda[PL]
 This is a step-by-step tutorial on how to import a 3ds model. It is intended for people who have no idea and weren't around in the OFP times, so that they can make their first addon (I suggest a rifle, and I supply an RVMAT I used for weapon).
-This is a TIP (Tutorial In Progress). I will add some pictures, example textures etc. in the future. I also encourage contribiutions.

   * all your hard edges should form closed loops (otherwise they will simply be turned into smooth edges).\\
   * when unwrapping try to avoid cutting along soft edges (will save you some fixing later, see below).\\
-  * model has to be tesslated into quads and tris (If you have multiple vertices along one straight edge do it manually - otherwise algorythm can create a zero-surface face out of these vertices positioned in line).

-When impoting the model gest cut along hard edges and along the edges where texture mapping is not connecting (places that were cut when unwrapping). In other words you get [[http://tactical.nekromantix.com/images/wiki/Import_3DS_edgesbl4.jpg|this]]. Note I was unwrapping outside of O2, this happened upon importing a mesh with UV coordinates and smoothness set in a correct way.

 Squarize means merging tris into quads, can screw up edge hardness. Merge merges back the edges divided upon importing, again an easy way to mess up edge hardness. Models do not get imported with textures anyway, you need to do that manually (see below).\\
-  * DO NOT bother to merge (or "fix") model manually afterwards. The binarisation will cut it apart once more anyway, save your time. Just pay attention when selecting not to leave any floating geometry... floating.

 **Fixing edges that shouldn't be hard:**\\
-  * Examine any smooth edges you have cut durring the unwrapping in 3D application - now they appear hard in viewer! Select with a box each verticle of each of these edges and use "SHIFT+E" to view vertex properties. There are probably two verticles. Press Shift+D to merge them. After dooing the same for other vertices along the edge you can select them all (carefull not to select extra ones) and press I - to turn the edge they create into a soft one. You might have to select the model and hit F5 (recalculate normals) to see results.

 Trick with normal map (if you get "rainbow triangles"):\\

 **Avoiding performance problems**\\
 Number of [[section_fixing|sections]] (or draw calls?) is the most important factor. Each group of faces  using different material or texture file is an additional section. Use only one rvmat per model if you can. Use specular map to make different materials look different (plastic, steel, wood...).
