Irrlicht Engine

Hello everyone... i'm newbie with Irrlicht..

I have to questions..

First of all.. i made a water effect like in the irrlicht example.. but the problem is that my terrain is really huge (i use the TiledTerrainSceneNode) so.. i don't know if its good to create a mesh with the real size of the terrain.. maybe there is another way to create the water... maybe more efficient?? don't know how to do it.. the effect way .. with the huge size works.. but maybe there are more efficient ways..

The other question.. is about lights... i want to create some fire.. and some effects in weapons (my game is an rpg game), this effects should irradiate some light... (like torchs) to iluminate some parts of the terrain... I have to use "PerPixel Lighting" i can search for it.. but don't know if that's the way..

Thanks in advance.. and sorry for my english (i'm from Argentina )

Ok, maybe my question is so stupid to answer.. i'm suppose i have to search on my own..

Mh, I don't know how much water you can see on your terrain. If it's not much I THINK it'd be better to use more smaller waternodes.
Because of needing many small waterplanes in my game I changed the Reflected Water that way I can use it with a non-square groundplane. Now I can better fit it into rectangle sized places.
