-**Ebud** said in BIS forum: The weapons are nice, but don't have proper lods for ARMA. They're not actually modeled down and just go from a high poly model to a billboard rather than model down each lod by 50%, and billboards for far lods shouldn't be used anymore.+**Ebud** said in bis forum: The weapons are nice, but don't have proper LODs for ARMA.

-**Skaven** said in BIS forum: All LODS modeled down, so it means the plain texture is over, I will wright a tutorial later explaining how I did it, basically I used p2m tool, [[http://www.sharecg.com/v/5169/software-and-tools/LithUnwrap---Free-UV-Mapper-for-Windows|LithUnwrap]], 3D Studio Max and [[http://www.mootools.com/plugins/us/polygoncruncher/index.asp|polygon cruncher]] in terms of polys/faces it's more or less as BIS's values in most I even used less, basically, I made a 50% decrease of poly/faces per LOD. All weapons now use one texture only, I used the [[arma:texturing:merging_textures|merge textures]] feature in O2, it's actually very simple I may also wright a tutorial about it, although Jackal already wrote once some time ago.+**Skaven** said in bis forum: All LODs modeled down, so it means the plain texture is over, I will wright a tutorial later explaining how I did it, basically I used p2m tool, [[http://www.sharecg.com/v/5169/software-and-tools/LithUnwrap---Free-UV-Mapper-for-Windows|LithUnwrap]], 3D Studio Max and [[http://www.mootools.com/plugins/us/polygoncruncher/index.asp|polygon cruncher]] in terms of polys/faces it's more or less as bis's values in most I even used less, basically, I made a 50% decrease of poly/faces per LOD.

 About texture merge: I've been checking your textures carefully and I think probably just one 2048x2048 file will do for all the tank however, if you decide to do merge them you should do it in steps and not all at the same time since you have two problems, 1 there are away too many texture files and 2 they have many different sizes. If you decide to merge them I think you should merge them by groups (sizes) first and than in the end join all of them. About texture merge: I've been checking your textures carefully and I think probably just one 2048x2048 file will do for all the tank however, if you decide to do merge them you should do it in steps and not all at the same time since you have two problems, 1 there are away too many texture files and 2 they have many different sizes.

 Once you normal map 1 or 2 models the rest is all the same you may increase or decrease the filter effect darken or lighter some spots but in reality it's really really easy, merging textures is also a piece of cake some code and a larger photoshop texture file is all you need in here. Once you normal map 1 or 2 models the rest is all the same you may increase or decrease the filter effect darken or lighter some spots but in reality it's really really easy, merging textures is also a piece of cake some code and a larger photoshop texture file is all you need in here.

-**Armored_Sheep** (BIS dev) about pilot proxy: Triangle that is placed in the model and represents the position of animated character is always relative to specific animation. Animations (RTM file, animation state) are defined in config. RTM files can be made in Oxygen using simple "puppet" rigid model of character (no skinning). For ArmA we tried to use basic rule that the bottom point is where the character has main contact with floor or chair. With releasing Oxygene2 we plan to publish also example character and skeleton models.+**Armored_Sheep** (bis dev) about pilot proxy: Triangle that is placed in the model and represents the position of animated character is always relative to specific animation.

-**[APS]Gnat** in BIS forums: Tip for bombs and missiles, when you make bomb and missile 3d models, give the GEO lod some weight (in KGs) but do not do Structure -> Topology -> Find Components. ie defining "Component01", "Component02" etc in O2.+**[APS]Gnat** in bis forums: Tip for bombs and missiles, when you make bomb and missile 3d models, give the GEO lod some weight (in KGs) but do not do Structure -> Topology -> Find Components. ie defining "Component01", "Component02" etc in O2.
  
 The "Find Components" option in O2 typically makes it so other objects are able to impact the geometry LOD, and vice versa. The problem is this means when a 100kg object doing 900km/h hits another static object, ArmA has a habit of making the static object fly off, especially ships. It also avoids problems like dropping bombs from a plane and having them "bump" into the plane itself. The "Find Components" option in O2 typically makes it so other objects are able to impact the geometry LOD, and vice versa.

 +
 +**Armored_Sheep** (bis Dev): ArmA engine does autocentering. The center of object in game is than affected by all vertices and all lods the p3d has. For proxies, such as weapons we use property Autocenter to prevent this. But be aware that if you place your model (for example building or car) far away off the 0.0.0 point in O2 and disable autocentering, you can brake for example AI path finding.
 +
 +Binarisation does the autocentering automatically for all objects except the ones with autocenter=0 property in geometry. Don't use autocenter=0, except for proxies or when you really have no other choice.
