- always make displacements lined up or else you cant sew 'em
- i recommend use power of 2?
- don't stretch the displacement to where the white lines are stretched out. this will make things somewhat harder.
(ex. a 1024 x 16 displacement)
It is okay to stretch.
- never turn a displacement into any brush entity, that won't compile it correctly therefore not compiling the map and instead loading the previous version
(I did this once)
- don't stretch the geometry to an insane amount. if you are trying to make a mountain, instead make a huge 2-sided displacement and subdivide it and make some minor tweaks (trees, acorns, other)
You should already know this.
- watch tutorials
- or you could always just never use displacements, they're a hazard
they're a hazard if you set the power to 4
