View Full Version : Display Tag override question

Let's say I have a null with 20 objects inside it.

over time, all of the objects inside the null fade OUT by animating the display tag's "visibility" percentage. This works fine.

But now, I need to add a display tag to the parent null itself and have that fade IN at the beginning. This won't work for me, it seems the display tags on the objects themselves override the tag on the parent null.... I hope this makes sense.

Is there another way to accomplish this?

I guess I could animate between an invisible texture on the 20 objects inside the null and just use the display tag on the null... but there are many different nulls, so that would involve a lot of work.

Any thoughts or solutions?

TIA,

Joe

You could just select all the display tags and simply animate them all fading in at the beginning, you should be able to animate them all in one shot with a single ctrl click on the keyframe dot once they're multiselected.

Thanks Per-Anders.... that did the trick!

I was planning to go that route, but didn't realize you could select all the display tags and keyframe all at once like that. That sure saved a lot of time.

I would use a User Data to drive all the display tags. That way, you would have to deal with one object instead of 20 (or whatever number of tags you have).
