Default Gravity confuses me

[stevenls]

Hey there,
I have a 23 story building built close to scale in Max, so it's just under 60m tall and about 18m wide.. like a tall apartment block.  I have a couple of spheres hitting it at various places, fracturing and then the peices fall down etc.

What I am finding though is there seem to fly out to far before they drop like they are just too light.  The do drop but it's just waaaay to exaggerated and I am not sure what to tweak.

The gravity is left at the default of -1cm  (my scene is 1unit = 1cm).  Should I be tweaking that or is there somewhere that tucked away in the physx settings that I should be altering the mass of the objects that are generated with the impact.

Thanks

You can click the arrow menu next to the gravity spinner to set it to a real-world value.

Hey there,
I clicked the down arrow, clicked 'Real world value' then it changed automatically to -1.633cm? Should I leave it at that, is that tyflow calculating real world gravity based on the scene settings?

That's a real-world (-9.8m/s/s) setting in scene units. It'll only be accurate in your scene if you've modeled things to scale.
