Color Group by VEX

[jingaa]

Hello there... I was working on something and noticed that , some group options changed in Houdini 16.

In houdini 15 i was grouping by clor with $CR<0.1 for picking red color but in Houdini 16 couldnt find a way for making that. 

And second of all how i can group like that usin VEX , any help???

 

Thank you!

Thank you for answer but this doesnt select group by color... I dont have enough experience with VEX this way dont know which part to change.

I couldnt find the way make a group by color in Houdini 16. That was very easy in Houdini 15 using $CR<0.1

if (@Cd.r < 0.1) {
 i@group_mygroup=1;
}

If you look again at the link that fencer replied to you that´s exactly what you need to group by color with vex.

Obviously they splitted the group node in different nodes. So you can create a "Group Expression" node to do the group and use the vex expression:

@Cd.r < .1
