hi

i’ve export unity terrain to blender as obj. for texturing mapping

but blender is so slow to contain 4 million verts in edit mode

is there any idea to make it faster?

my pc specs

CPU i7 3960x
ram 32 GB
GPU GTX 690

blender usage at editor mode

CPU 0.5% to 20%
RAM 9.2 GB

try to turn off history undo in user preferences
but you wont have undo

may be split your ob in 2 or 4 parts

happy bl

step 1 does’t make deference

step 2 i need to split it to 8 times to make it smother enough to work with it but i’ve to edit 24 terrain if i split it thats will be 192 meshs

any idea please or another software

i don’t know why my last post was deleted

but i’m waiting for an idea

history should make a big difference
and use a lot less memory
what is the file size in MB?
how many modifiers on that mesh data ?

how many images UV are there ?

on an I7 splitting in 4 would give 1 millions verts and that should not be a problem
what else do you have on this mesh data ?

i’ve 32ram GB blender uses 2.6GB

it’s frames problem
in object mode FPS = 60
in edit mode FPS = 1.1

can i hide or resize vertices(black points)
i hope you gave me a solution
thanks

it might help to select a part of mesh and hide it
if possible

well if you have anim then remove it work on your mesh then redo your anim with the right set up for you mesh

What speed is your ram? When you are in the millions of verts ram speed matters almost more then cpu speed (assuming cpu is some form of I5 or better at least)
