its ~2000 triangles - which is about the same polycount as the siren or chair models have - also "minor" props, imo. before i started with my tf2 modeling i studied quite a bunch of original tf2 models to get a feeling for the work- and polyflow. I realized that they are quite heavy on the polycount-side which is because a lot lot lot of the details are modeled out. especially the buttons on all of the consoles and stuff. and since you won't be putting these fusebox 10 times in a row, it's alright, imo.
i mean, one open is enough, everything else will be repetetive. the rest may be closed fuseboxes, which will have far less, so its all good in the end, in my opinion
thx for all your feedback so far, guys !
