model preperation

ok so now i have to worry about surfaces as well.... :(

does this sound right to anyone
my plan is to model the terrain all in one big model
create the image map while its all connected this is the easy bit.

then select all the polys on the floor area, cut out and save as a separate model, when i load into blitz i will have 2 entitys so i can detect for the floor and then the wall.....but when sufaces are mentioned i have to keep this low...by preperaing my model in this way does this mean i have 2 surfaces...even though parts of the level do not touch the next part...like over a canyon

this pic might explain in better

AFAIK, the floor will have 1 surface, and the walls will have 1 surface.

EDIT: Shouldn't this be in the Blitz3D forum?

thanks

i thought of putting in the newbie section as that describes me..but i thought it was more a model prep question

No problemo, Dave :)
