The arch shape is your friend here, plus you'll want to keep some curves as simple as possible to save you some work.
However, I assume you've got a nice circular tunnel here, but I don't know your actual situation. Got a screenie?
out << i;
out.close();You don't get it do you?Do you, FresheD? Giving a rude answer like yours only stirrs up these discussions. There's no need for that. Tell them what they need to do to get help in a polite way, or don't tell them. No need for fighting.
Select everything, null it, texture only the faces that you will see, tie it to an entity. Saves w_ and e_ poly like nothing you've ever seen.I don't know if this happens with Nem-generated terrain, but if the whole terrain patch is made one entity an absurd lot of unexpected face-splitting may happen. Perhaps I pushes things too far in Mudanchee (the HLDM version), but be cautious.
And after, if you want a lot of details, put some CLIP brush, to avoid the player get in stuck... laughing -Func_illusionary does a nice job for details too...
