Hi all, just wanted a quick sense check.

When I started out making my terrain thingy, I wanted to get to being able to render a 4097x4097.
I have gotten there and everything is happy and well. (yay).

However, I am creating a big normal map, 4097x4097 (on my lappie I have to scale it down to 2048).

So now I obviously want to go one more, and render 8193x8193, and I don't really fancy creating a texture that big.
So I want to create a normal map for each terrain section (which are 64,128 or 256 depending on my mood at the time).

I just wanted to ask if I am asking for a world of pain, creating that many textures?
(which will have to be set before sending each section down to render).

My thought was that I could maintain a big sheet of active sections, and then when a section wanted to load its normal map, it would load it into a slot on a big sheet
(So I would have less textures, but they would be bigger, and would be changing over time).

So to summarise I am looking for any warnings or advice, concerning generating lots of smallish textures.

No worries if no one has anything to say, my next step will be to see what happens when each section has its own normal map.

Have a nice day.

It's really hard to generalize without knowing exactly how many is "many"!  (and how often new textures are being created, etc).  But it's totally common for games to use hundreds of textures, and I would guess quite uncommon to draw a terrain using just a single giant texture.

Cheers Shawn.

I was probably overly fretting, just wanted some reasurrance that I wasnt wondering down a path of utter madness.
