Accurately Recreating Things from Movies

Does anyone here know what specific props (and the respective movies they correspond to) were scanned when DICE used photogrammetry during the production of Star Wars Battlefront? For example, I've heard that Darth Vader's model was scanned from his Return of the Jedi costume, but I don't know if this is true or not. In any case, I think it'd be a good idea to try to identify the source props used as the basis for DICE's models and see how they differ and what could be done to make DICE's models more film accurate. There already seems to be a fair amount of interest in this sort of thing, given that there's a bunch of mods on Nexus that try to make certain models closer to their screen counterparts.



If the DICE Vader was scanned from the ROTJ costume, does it differ in any way? I haven't really noticed any differences, but I'm pretty sure many Vader enthusiasts out there could easily identify any sort of inaccuracies, hehe. 

To add to this relatively old post, I'd like to say that DICE edited the scans, at least for Vader.

Either that, or they mismatched props and/or did improper scans. One thing that is noticeably different from the original suit compared to the game model is just the overall proportions of both the body and the suit pieces.
The chestplate has been made to bend with the actual body, and just jut out from the body at the corners. They also stretched the gloves and even the suit itself to fit onto the 6'2 plastic body they scanned the suit on, which means that there are a lot of inconsistencies in the way the suit moves and wrinkles compared to the films. Had they put the suit on a 6'6 body as they should have, they could have evaded this problem. But, there's an even larger issue.

The helmet.

From a glance, it isn't too different. But if you compare the helmets, you immediately notice MAJOR changes to the sculpt from the actual prop. Number one: They have completely removed the two-toned coloring of the mask from this scan. It's all black. Not only are you losing the details of Vader's mask in the sea of black paint and reflections, but now you make the chestplate stand out even more with that Stark White color they went with over the Gunmetal Gray of the original.

Number two: On both the chestplate and mask, they have ditched the two roughness settings of the paint, and have made both surfaces SUPER reflective. Now, on the dome, this isn't an issue. But the gunmetal portions on the mask and chestplate are meant to absorb much more light and make it look larger to enhance the details (Hence why in some shots, these details are brighter and/or darker than others while the black normally looks about the same color). This means that the white stands out EVEN MORE and the detail of the mask is EVEN MORE messy and incoherent because it's all blocked by admittedly pretty nice reflections.

Number three: They resculpted the mask for some reason. The dome was made to be symmetrical, and (I think) smaller, while the Mask has just been misshapen. It's longer, and thinner in the front. From an angle, it looks fine, but from the front it looks.. off. They also reshaped the neck, and now it stretches when Vader looks around, making it look less like a helmet and more like his actual face. This, to me, is probably the most noticeable change aside from the overall body proportions being off.

Now, I get that some of these changes (Like the symmetrical dome and the neck) make it easier to rig and avoid other issues, like clipping. But, to me at least, it heavily impacts Vader's look when he is slimmer, shorter, and misshapen.

Given that they did this for Vader, I would imagine that other characters have similar issues, but I haven't paid much attention to the other models.
