Do you have installed script mods? One of them is affecting the alpha of the hands component in peds. Move all script mods to another folder, and add one by one reloading scripts in game until find the bad script.

@danydino Is one of my all times favorite video games vehicles, is in my list of vehicle mods under WIP. Expect it in March.

@zh465 A 4096 x 4096 pixels texture uses a lot of VRAM (48 Megabytes each one) overloading too the UVs and shader per-pixel calculations in the GPU, stressing the hardware (Rage engine in GTA V applies 8 passes to render each pixel on screen, so just multiply and be amazed with the percentage of the game process are you using for a simple 4k texture).
For the health of the performance and hardware, the limits for each model is managed by the game engine. You can't abuse about that, the engine only assing ~10 Megabytes for each model including textures (approximate value when we see the most heavy models from the game with already compressed textures), and the textures are compressed to Direct Draw Surface (DDS) with Mip Mapping generating more sub-textures. So, always use the lowest resolution possible because each Megabyte in a open world game is precious and Rockstar knows that.

@nerovergil @Yelrix Request accepted with variations including jacket and no jacket.

@fripgrass Is possible, but is necessary more tests. Is in my mods to do list for this year

@Kwebbl Is possible like said @SkylineGTRFreak and the another way is with a simple script to simulate the bolt shoot and being enabled when the model is selected in the weapon wheel, in that way we can control too the crossbow model variations and arrows/bolts behaviour (features like staying attached to the objective until we pick up the bolt/arrow).

@SkylineGTRFreak I know well that, I'm making mods since 2006 with different nicknames and with GTA IV nobody knew the LOD improvement in my peds and vehicle mods but no one complained about vanishing models or performance issues.

The people just want visual quality without affect the performance like a native GTA V model. For me the LOD usage is necessary without forget the extra work, even if is just to center pivots, assign materials, put flags and add to hierarchy. The hardest step is the LOD creation, but actually that can be automatized in few minutes with some free software generating easily two or more LODs with different polycount in the same process (see indie development).

The true problem is when a modder takes models from CGI to convert in GTA V and not apply retopology. Is not just vehicles, we can see even simple props like weapons exported directly from ZBrush (for example) with millions of polygons and the modder not realize about that.

@baba0rum @ReNNie Oficially I'm starting in modding with GTA V and LODs will be included in my mods. I have some not released, releases soon.

@Frazzlee LOD models is not for fun, is a necessity for a game, including the modding. Is question of offering quality and things well done without affect the gamming experience (all we are gammers and dislike the lags and models vanishing in distance). Build a LOD is simple, search tutorials about and exists too free software to do that for us.
Not having time is not an excuse, it's just the pretext for not learn and put more effort into something.
