i have a problem with sculpt mode. if i create a cube subdivide it 4 times use the first brush when i come into sculpt mode and try to sculp the cube, nothing happens, and it says “Hide, mask and optimized display disabled”
the first picture is mine, the second is what i see on other videos and stuff
Apply the subdivision surface modifier so you are actually sculpting on the subdivided mesh or preferably use the Multires modifier which is designed for use with sculpting
how do i do that? im new to blender 
Apply the subdivision surface modifier
Press the ‘Apply’ button in the subsurf modifier settings
or preferably use the Multires modifierwhich is designed for use with sculpting
Delete the subsurf modifier (X icon in top right corner of subsurf modifier) and add the multires modifier exactly as you added the subsurf modifier, from the modifier list.
im new to blender
Go and read the modifier link above and watch some of the millions of tutorials on tutorial sites like cgcookie or youtube
found it now! thank you so much!
