Assigning material to prim group

[nicholas_yue]

Hi,

  I have the following geometry with prim group.

  I wish to assign a specific material to a specific prim group, I am using an Attribute Wrangler SOP to perform the VEX operation but can't work out the variable name I should be using to do the comparison

printf('%s',s@path);
printf('nicholas test\n');

// if(match('*sphere*', s@path)) s@shop_materialpath = '/mat/red';

Cheers

Generally you'd just use the group mask parameter on the primitive wrangle itself, rather than a conditional statement.

If you have to use a conditional, though, it'd look like this:

if(inprimgroup(0, "sphere", @primnum)) {
	s@shop_materialpath = "whatever";
}

This wouldn't let you use wildcards, though. It's better to just use the group mask parameter on the wrangle.

or directly Material SOP for that matter

but also you should be able to use wildcards, adhoc groups (or any syntax that group fields allow) with inprimgroup() function
