== SMD exporters ==
{{seealso|[[:Category:Blender]] for tutorials.}}


The only plug-in that can export [[reference mesh|reference]], [[collision mesh|collision]] and [[skeletal animation|animation]] SMDs is Dvondrake's.
{{blender|4}} is a free and open source [[:Category:Modeling|3D modeling]] package that can be used to create models for {{src|4}} and {{src2|4}}. Blender has also been available on [[Steam]] since April 3, 2015, it comes with automatic updates but has no support for the in-app Steam overlay currently.

* [[UV map | UV mapping]]
* 3D Texture painting. (see [[Skin]])
* Texture baking (see [[Normal Map Creation in Maya]] | <span style="color:red;">'''Note:'''</span> this is for {{maya|4}} same principles applies in {{blender}}).
* Weight painting, Rigging, Animations & Shape Keys (see [[Blender#Animation | Animation section]]).


* Dvondrake's exporter has [http://filesmelt.com/downloader/smd_vta_export.zip been modified by windwakr] to add [[flex animation]] (VTA file) export.

Blender has a very unusual interface that takes some getting used to. Matters aren't helped by its preference of hotkeys over of visible buttons. Nevertheless, learning it is quite achievable:

*# If you find you need to flip any polys, either use {{key|Ctrl+n}} to make everything point outward, or select those that need to change and press {{key|w,0}}.
* Because Dvondrake's exporter only exports the currently-selected object, you can store as many meshes are you like in the same .blend file. Use scenes and/or layers to easily manage the different elements of a model.
*This is simply a modeling tip: If you intend scaling the model or the armature, do this in Edit Mode. This can help not having problems with dimensions.
