Can CSG "Solid Modeling" Lag Your Game?

Asked by

I've been curious about CSG "Solid Modeling" that can cause lag to the game. I heard many people say that CSG could lag your game. Is that true? I'm just curious about it.

Thank you for your time!

Doesn't solid modeling decrease the lag in your game?!? Since there is less parts for ROBLOX's Physics to worry about? UserOnly20Characters 890 — 9y

CSG models are probably more expensive for physics (at least if they're not anchored); but they're probably cheaper for rendering BlueTaslem 18071 — 9y

Yes it does, if you know anything about modeling off of roblox on other things, then you should know more triangles = more lag, https://gyazo.com/a2b59d6c2414c54a28ed5c4454df6b84 Triangles are the shapes that make up a part the more you have then it lags more. For example a single cube has 6 faces and 2 triangles in a shape, https://gyazo.com/2b2d74464371e363812c33ffc31d5e63 But theres one more thing this one I dont understand too much but this can happen too: https://gyazo.com/f422b86db6538758aeef48391eb65f93 But in the end, CSG models do lag but only on how complex they are, https://gyazo.com/71304190ec4e3c276cb459b3e890e17e both of these would lag but the part on the right would lag more. The lag CSG models make isn't alot but if you have lots of CSG models in your game it can slowly add up to lots of lag. Also.. A tip, CSG does lag but not a lot if you have a model with lots of parts https://gyazo.com/e093bbd21a63ddfe4a7e21a7c9471363 it will lag more sometimes CSG is better because it can turn lots of parts into one more triangles do lag but not as much as more parts https://gyazo.com/c8cd48f88082b5f550de46f2628461a9

CSG models will have fewer triangles than the corresponding parts that made them up. Obviously less complexity = better performance, but CSG should REDUCE complexity, not increase it. BlueTaslem 18071 — 9y

your right about that part, but more parts are laggyer than 1 CSG model not because of the triangle it has but because of roblox physics it would have to load 10 parts but if those were put into 1 part it would lag less lucas4114 607 — 9y

I think CSG doesn't lag your game (remember everyone's comp isn't the same.) I've only heard one bug that when you solid Model It turns your Union transparent, even though the transparency of that union is 0.
