hi guys:
we are using unity’s terrain system,but we find when we has more and more complicate terrain the draw call for the terrain gos up very fast.it impacts the fps greatly.so we decide to draw terrain on our own.
but we have a problem,in the TerrainData,the detail map only record the density(a byte value?) and we guess unity generate grass mesh dynamicly. now we have to figure out how the grass distribute on the terrain so we can get rid of unity’s terrain.
any information may help
thanks in advance
Reduce the pixel detail and detail density etc.
If all else fail, try to make it in another terrain engine or just make it in a modelling software.
