I don’t know if this is the right place to ask this, but as do I need it for the game engine, I believe it’s ok.
What I’m looking for is the most efficient way of level creation for an FPS (singleplayer MMS). It sounds easy enough, but once I gave it a try I felt utterly confused as to what method I should use. So I came here looking for an advice, alongside any helpful tips regarding terrain creation for the BGE.
For instance, how big should it be?
Do I need to follow the 1BLU = 1m rule, or is that relative? - especially as I’ve found it quite hard to work with objects/areas as small as that.
Next, what is the optimal resolution for the terrain texture?
I’ve found it quite confusing at times, as texture resolution does affect framerate (and I’d like my game to be playable on computers with rather low-end visual cards). How much is ok; good; and too big?
Would you recommend one giant plane with a huge texture, or smaller slopes of land put close to each other (especially for uneven terrain)?
And is there a way to paint textures directly (like in Unity), or do I have to create the full texture in Photoshop and import it as a final version?
Speaking of… does the terrain itself need normal and spec maps, or is that an overkill?
I believe these are not the only questions I have about terrain creation, but it is the majority of them.
