I read that textures are limited in size (to 256*256, I think). Is there a way around this for doing things like texturing the ground?

Thanks!

power of 2 upto 512

e.g.

16^16
32^32
64^64
128^128
256^256
512^512

this is because 512^512 is the most commonly supported by graphics cards, and really you shouldn't need anything over that, however allowing multiple textures to be assigned to Matrix rather than a single 512^512 would actually be nice

some cards are not up to 512 but only at 256 maximum.
ITs a bit annoying but it can be worked around

Well, let me explain what I'm trying to do, maybe I'm just not taking the right approach.

I've built a "combat arena" type thing where a vehicle drives around and takes out robothings. This arena has walls around it. I could make the walls by simply putting up plains and texturing them, except that would make for REALLY, REALLY BIG pixels if I can only place one 256^2 texture on the entire wall!

is there an easier way to do what I'm trying to do? Is there a way to TILE that texture across the plain?

Any help would be GREATLY appreciated!

Thanks in advance! (either way)

Yeah, you can scale the object texture as well as scrolling it. The smaller you scale it along either the U or V axis, the more it tiles in that particular direction. Look up the texture scaling commands in the Basic3D help section, there's an example in there.

Excellent! I tried it out and that was JUST what I needed!

Now is there any chance you could give me some pointers in dealing with object to object collisions? <hopeful grin>

Thanks either way!
