Hello everyone,
I'm following Robert Magee beginners tutorial "Nodes, Networks & Digital Assets" and I have an issue.

In the "Copy to Points" node, if I check "Pack and instance", my instances turn grey. But if I put the display flag on the "Switch node" (placed right before) where there are the points, I can see that those points have the color I'm expecting. It seems like the color attribute is "lost" after this "Copy to Points" node...

How can I check "Pack and instance" and still have the color?

I hope it makes sense... sorry I'm a total beginner with Houdini.

Thanks for your help!

Version is 20.5

The viewport can relay color information to you, however, it does not look inside packed primitives for that information. Once you pack them, they become a single point. It's like a ZIP file, you can't see what's inside at a glance. Try an upack node after the switch, and you'll discover your attributes are still there.

I am precisely having the same issue! If I don't check it, the colors and the rubber toy material appears, with of course the massive amount of polygons almost to 1 million.

Tried unpacking, as well as changing attribute from Cd to instanceCd. No joy.

you may need to be more specific since in the viewport you should see the color on top of packed prim multiplied with the color inside
