multiple detail maps

how would I go about implementing multiple detail maps for a terrain, based on type? For example, one detail map for grass, rock, lake bed, etc...

Are the detail maps per material only?

 

do you mean detail like an AO map or being able to tile multiple textures? for multiple textures search for layered shaders - there's at least one on the wiki and a few threads about it. you use alphas to define what texture goes where.

there's a project you can dl that has a 4 texture terrain.

 

Hi guys,

as Marble was also questioning recently, it seems to me indeed that combining the strength of bump maps and detail maps can be powerful.
On top of this, I as well see the relevancy of multiple layers with each his own alpha, detail and bump maps.

layer 1
main1+detail1+bump1+alpha1
layer 2
main2+detail2+bump2+alpha2
...
layer n
mainn+detailn+bumpn+alphan

what do you think and can the code be that flexible for us to specify how many layers are used?
