Is it ok to assign a material in a while loop..
eg:
while(1)
blah blah
my.material = test_mat;

wait(1);

it may eat more memory ? i am not sure.

It shouldn´t be worse than my.skill1 = 10; in a while loop .

Thanks ppl, I gave it a go didn't see any lose in framerate or any other
problems but that was with only two models. I'll add the material
to more models and keep an eye on things..

Thanks again..

all it does is tells the model to enable a material, so it's not much more than changing variables and skills in a loop, considering material really is a skill. (it's more or less what Slin said)

Thanks mp and Slin that answers it more clearly..
