====== Texturing ======

For texturing you can use things such as Adobe Photoshop, Paint Shop Pro, Gimp or virtually any paint program.

You should use the [[arma:texturing:texture_naming_rules|ArmA Texture Naming Rules]] always when texturing.

**Panda[PL]** said in [[http://www.flashpoint1985.com/cgi-bin/ikonboard311/ikonboard.cgi?;act=ST;f=76;t=66600|BIS forums]]: No, don't use different textures for each LOD. In ArmA if texture is not needed in high resolution anymore (because of distance or low framerate) the engine automatically scales it down in memory (drops out every one in two pixels, that's why all textures need to have dimensions of powers of two). On the other hand loading a texture from HDD or from ram into the video memory is performance consuming and will cause FPS drops. So use the same texture for every LOD and let ArmA worry about it.

**Ohara (BIS dev)** said in [[http://www.flashpoint1985.com/cgi-bin/ikonboard311/ikonboard.cgi?;act=ST;f=68;t=66677|BIS forums]]: Drop of FPS in vegetation is caused by overdaw, it means that grafic card is not able to draw so many pixels that scene needs. When GC draw scene, it automatically cut hiden pixels, BUT only if this pixels are not alphatransparent. Vegetation is builded from polygons with some opacity textures, so this cuting (early Z test on HW) not work here. There is no simple solution, better performance will be with low shading detail settings (simplified pixel shader), but overdraw is still there. Also using of worst LODs will not help so match, because less polygons means worst tree shape aproximation and final surface (what is most important for overdraw reduction) will be similar. We are still woring on some research in this area.\\
He concluded more (which really doesn't help us ArmA modders): Yes, we found solution how to reduce overdraw about 25%, but this solution need diferent representation of tree surfaces and vertexes (diferent model and binarisation of this model and diferent way, how to switch vegetation lods). So it's  not usable for curent vegetation data and will be used in next projects. Alphatextures mean also masked textures (that is 1bit transparency or opacity if you want and we use them).

====== Overview ======

Basic tools for texturing are any sort of image editing program, we suggest Adobe PhotoShop with [[arma:tools:paaplugin|PAAPlugin]], then to fiddle with ArmA specific stuff use [[arma:tools:texview2|TexView 2]].

You can use [[arma:tools:oxygen2|O2]] to apply the textures into your p3d model. You must create the rvmat file for your specular and normal maps, the rvmat is then applied normally with O2 into the model.

====== Specular Maps ======

More details on specular maps read [[arma:texturing:specular_maps|here]].

====== Normal Maps ======

More details on normal maps read [[arma:texturing:normal_maps|here]].

====== Merging Textures ======

Merging textures in O2 is possible, read [[arma:texturing:merging_textures|here]].
