Specular map is a complex bitmap. Each color chanel has its own purpose. You should understand well the way of calculating pixel colors in scene before you paint those textures.

As written in http://community.bistudio.com/wiki/ArmA:_RVMAT value of each pixel is calculated with RVMAT values and engine lighting values.

Texture _SM has diffuse values in RED, specular in GREEN and, Specular power in BLUE chanel. _SMDI does not use RED chanel (better compression) GPU calculates those values automaticaly as Diffuse = 1 - Specular.

When you use specular map - diffuse, specular in RVMAT should be 1. Then paint B/W map with maximum specular and minimum specular values you imagine on surface. Than choose minimum (black) and maximum specular (white) values and change the bitmap levels to those values.

(Note to self) At some stage it might be a good idea (of course it may just as well not be...) to have a listing of common rvmat material settings with a reference picture. Maybe specifying shaders, values etc. for common materials such as metals, masonary etc. Might be something OFPEC might be more suited too as it may get 'out of hand' with a 'thousand' blood textures/materials or something just as stupid... anyhow, this is a reminder note to look at it in the future...

(Another Note to self) Start a discussion at some stage on the forums regarding bringing new character models in. Specificaly, different sized models from the current BIS content. This discussion would result in some general consensus regarding one (or more) 'sizes'. That is, all current rtm's and units are based around a model size of 1.8 metres. (apart from some which are unit specific ones...)If there was some community consensus, then perhaps (as an example) one could have some 5'6" (165cm) characters, or 4-5 ft. characters. Also, a characters volume would need to agreed upon. These, sorts of issues would only be necessary if there was a desire to have rtm's that could work with models from disparate sources. Also, a naming convention, similar maybe to bis's but also including a size reference.


[quote=Armored_Sheep,April 23 2008,03:56]For working animated material that is bind to vehicle damage you need:

1) selection on your model that contains faces with animated material (switch one rvmat to another) 2) damage materials 3) section defined in model.cfg for the animated selection 4) hitzone definition in config.cpp in class HitPoint* where the selection is written 5) class dammage in config.cpp where switching materials are defined 6) Model and all its sources must be binarised (packed) in PBO[/quote]

Undocumented O2Script 'callRuntime' command parameters

Following is a list of (so far anyway) undocumented O2 commands that can be called via the O2Script command 'callRuntime'.

eg.

_LoD callRuntime "isolatedpts";

From O2Script make a call to the runtime to 'select isolated points'.
