    Default OR & Polygon limits.

    I know the original stock MSTS had a polygon limit, but I'm wondering if Open Rails have the same limit, or can it accept higher res. models?

    I've yet to find an upper a limit, and I have built several scenery objects well over 12,000 polys....

    As a test, I created a loco with 330,000 triangles. OR loaded 2 of these locomotives at the head of a train and ran with no problems.

    I did not skimp on details for my recent Tank Car upload, I don't see why I need to adhere to MSTS limitations if ORTS isn't making me do so.

    Well, I know TSRE5 can get a bit glitchy with high quality textures, (example: 2048 textures) but I haven't heard of a railcar limit yet. It would appear that its kinda just based on what your computer can handle.

    Hi Folks,

    Yeah - initially MSTS would start throwing artifacts on models around 10,000 or 11,000 polys. I never really noticed if BIN improved that - as I was an early adopter of ORTS.

    Derek Millers steam locomotives exceed 70,000 or 80,000 without issue - with long trains - on detailed routes - with multiple locomotives.

    Multiple 2048 textures on steam locomotives are now the norm for me - without issue - I use 1024 on freight cars.

    As someone who's tested ORTS performance extensively - the biggest frame savers are using model LOD's (especially on freight cars) (yes you can make the transitions seamless) and minimizing Draw Calls. It's better to use a single larger texture in place of many smaller textures.

    Regards,
    Scott
