I used CCD but doesn’t seem to work goodly. It still keeps phasing through. it works better with CCD, terrain, etc disabled except force deactivation and setting collision margin to 2mm work better. Doing this way doesnt solved it but at least prevent player at 3 unit speed from phasing.
But using work around, @Simonrazer found a way to prevent player from phasing completely->http://pasteall.org/1355778 (I can’t find ccd, in file. forgive me if it is just there and i am not able to see).
