Can a particular object's reflections be isolated? 2024年12月17日9:01

1. Yes, you can assign LPE tag to your object and then filter just for reflections hitting objects with that tag

2. You can try filtering for refractive paths ending with B event which stands for background, to get something like Alpha for areas that hit nothing

Both are described here

How to make a group based on camera view? 2024年12月16日22:52

you may want to make sure you are expressing your camera position in the current object space, rather than disregarding the object transform

string cam = chs('camera');
vector ndc = toNDC(cam, v@P);

int in_frustum = ndc[0]>=0.0 && ndc[0]<=1.0 && ndc[1]>=0.0 && ndc[1]<=1.0;

i@group_visible = 0;

if(in_frustum){
    vector pos_cam = ptransform( cam, "space:object", {0,0,0} );
    vector dir_cam = pos_cam - v@P;
    vector pos_ray = v@P + normalize(dir_cam) * 1e-3;
    int pr_hit = intersect(0, pos_ray, dir_cam, set(0), set(0));
    i@group_visible = pr_hit < 0;
}

Just wanted to ask that The Shown Info from a label could it be in block letter?
If you mean upper case use toupper() [www.sidefx.com] expression function
