complete terrain ent clipping away

I have 2 terrain entities created , each is 128 by 128 vertices with 256 size for each terrain cell .

the first terrain is centered at 0,0,0 .
the second terrain is centered at 0,0+first_terrain.max_y*2,0

both use the same material and textures/skins .

the second terrain is wholly clipped away at certain angles by the engine , even when I am directly on top of it ,while the first terrain remains visible .

why would my second terrain clip away completely even though my camera is right on top or near it ?

Thanks.

I think it is a level_ent size problem, when camera goes out of it terrain is clipped. I had something similar problem earlier.... you can set its min_x and max_x vectors manually.

I tried setting level_ent min and max to -90000 and 90000 , before , but it still happens at certain camera angles ,no matter where the camera is positioned ,it clips away at pan 19 and pan 157 also tilt -40 ..

edit : got it , added a wait (1) after each terrain was modified

wait(1) is our best friend (I laughed on last AUM interview, when read that if something does not work add some random waits it is so true)

Its a little bit sad... I mean programming is ment to not understand the code but it actually works somehow...

this one is on me , I sequenced 2 terrain's modifications within one frame , jcl said it needs a frame to update so makes sense to wait a frame for each terrain piece to do it's updates , what is difficult however is to actually figure out that some bizarre behaviour is the result of a needed wait ,not something you would always expect .

I had a smile when i started noticing that somehow what I read in aum became true in a creepy way ,in most cases the wait seems to do magical unexplainable repairs ,for instance take my recent bug report where a wait somehow made something work wich aren't suppose to work ,and turned out to not even be a frame wait problem ,but by Jupiter how it read my mind I don't know !

the wait seems to have a much bigger importance than one would expect ,there seems to be a lot linked to what happens after one frame under the correct circumstances .

the "make game" or "fix game" button must be titled "wait"
