Hello everybody.

I search a way to randomly apply some material on some objects.
I have 54 objects and 6 materials (6x9 = 54. I guess you understand ;) )
I want to randomly select object 9 by 9 and apply a material in each time. Of course the objects that already be select and get a material can't be select again.

All of the objects already have a material on it. I think to freeze the objects i select and test the freeze to avo´d this object be selected again. And when all objects has changed material, unfreeze all.

Someone has an idea to make it ?

Thank you for your help guys :thumbsup:

Hi Bruno,

You can use something like this:
for i = 1 to selection.count do selection[i].material = meditMaterials[((i - 1) / 9) + 1]

It basically loops through your current selection and assigns materials from 1 to 6. You can see that "((i - 1) / 9) + 1" creates values from 1 to 6 throughout the loop.

for i in selection do i.material = meditMaterials[random 1 24] would do what you need Laurent.

ok I got it by myself, thx!
But how can I specify the material range with a spinner or something?
rollout forege "random material"
(

label label0d "this tool apply random materials"

label label1d " from MaterialEditor to selection."



button un " RANDOMIZER - 6 materials "
on un pressed do
(for i = 1 to selection.count do selection[i].material = meditMaterials[random 1 6.0]
)
button deux " RANDOMIZER - 10 materials "
on deux pressed do
(for i = 1 to selection.count do selection[i].material = meditMaterials[random 1 10.0]
)

button trois " RANDOMIZER - 15 materials "
on trois pressed do
(for i = 1 to selection.count do selection[i].material = meditMaterials[random 1 15.0]
)



)
createDialog forege width:220 height:130

Or check the RandomMat script available here:

Laurent,

Just add a spinner control like: spinner toVal range:[1,24,6] and then use toVal.value instead of max values like random 1 toVal.value
