Hey guys,

 

I'm designing a huge outside map, which kinda eed to have lower parts in the terrain where for example; rivers can be drawn.

Is it possible to lower the terrain on several parts?

in LE2 you had to use CTRL+mouse button. but how could this be done in LE3.X?

 

Cheers guys!

Thaks in common :D

while its representation is a 3d mesh or better a bunch of smaller 3d meshes it is bound to heightmap which is limited to 0..1 or 0..255 values depending on the internal format. Also a terrain system is a very performance hungry system in every engine so the culling, position calculation etc needs to be very optimized and if you can rotate, move or scale a terrain you always need add some cpu consuming matrix math to nearly each calculation.

 

I agree that moving a terrain should be possible without much performance loss (it more or less just an offset addition), but scaling and rotating are too calculation heavy for such a system and can break the whole performance.

it was possible in LE2 @klepto2 it did it before, at least in LE2.3 and 2.5 ..

What was possible in LE2? going below 0? no klepto is correct. I think you are thinking of the altitude feature but that was afaik just scaling in the Y direction - which could be used to move the terrain above the global 0@Y.
