T4M Project

What that and why u e it !

The T4M is an terrain tool.It is an alternative of Unity Terrain using your own geometrie made with an ! Modelingtool "Maya# $arth%cul&tor# !% MA'# (lender...)

Initialy the T4M targeted the mo*ile device# *ut a lot of &eo&le find other *enefits at theT4M +, T4M is a tool that allows users to im&ort geometry into Unity to use as a terrain., the T4M for we* and mo*ile is the small size of the *uild# only one draw call# fast loads&eed and great &erformance"on old devices too)

%o# I decide to targeted all &lateform and &ro&ose a com&lete solution "e'e&t + $levationtool yet)The T4M included te'ture &ainting# &lanting trees - grass# and have an /! system and(ill*oard on every im&orted geometries.The T4M can also convert a Unity Terrain into geometry retaining the *lend te'ture and thefirst four s&lat te'tures and use it with all *enefits than an im&orted geometrie 0 T4Msystem.

All features are com&ati*le with Unity 1ree and ro
