A support for exporting lights into GTA models have been added. To the moment the only model files confirmed to support exported lights are .yft files. Original game models have lights in .ydr too, but these have not yet been confirmed to get exported properly.
You can import any model with lights and copy pre-configured light into your scene. Lights come up with some parameters in used-defined options window and are equipped with default parameters if these are missing (light created in ZModeler with no extra parameters).
As this is a "work in progress" update, I would like to get reports on what effect different parameters produce to your observation. I've tested some of them to the moment, so can't give a full list with explanation. Here's a screenshot of parameters box in current release. These are a subject to test and probably refine for better usability.
Power = the strength of light (two values control the strength on light, it's up to you to test light behavior with different values). Probably range-specific or an attenuation-specific at low/far range.
Flags = a set of bit-flags to switch on/off various features. ranging from 1 to 32 inclusive. To the moment known are:
#8 = blurred shadow (in combination with #9 only)
#9 = enable shadow;
TOD = time of day activation. E.g. 0, 2-5, 18-23 (0 = from 00:00 to 01:00; 2-5 = from 02:00 to 06:00, and from 18:00 to 24:00)
ShadowBlur = blur of shadows (any value from 0 = no blur, up to 255 = fully blurred shadows)
Subtype = unknown, probably insignificant; may be corona-specific;
Color3 = unknown, seems to have no effect;
Params1 = unknown set of parameters;
Corona = corona settings; seems to be [power, size, unknwon, hdr multiplier]; suggest your meaning for these values if you find something;
Shadow = offset to shadow-rendering point. allows to move light into some object and shift shadow rendering point out of this object to prevent artifacts. For example, streelight bulbs light-source is behind bulb glass cover, and this shift value allows to render shadow without bulb glass cover being dropping shadow (just like there is no such on the way of light emitted from bulb).
Feel free to mess with original game files import/export and report your observations (whether some features stop working or something get missing or messed). For example, i haven't tested flashing lights in any way.
Note, the filter update is marked "Beta", so you need to enable "Install beta updates" in Settings->General->Network to get this version downloaded. I'll keep it in beta stage for a while as there are some important things unresolved yet.
