Extract Vertex Painting informations from UE into my HDA 2020年11月20日5:48
Hey folks !
I try to deal with some stuff since yesterday at my work, i'm really stuck and need help.
To resume :
Actually i have an HDA running in UE4.
I give him some objects inputs.
I need to extract the Vertex Color of theses objects.
But i can't figure out how to deal with that.
-I have paint vertex color inside UE, on the original mesh.
-I have also paint vertex color directly on my HDA.
The two won't work, i can't extract vertex color from it.
I have the sensation that it's ok from houdini to ue, but not the inverse.
Maybe this is not possible.Maybe some of you have the anwser.
It's someone can help me, it'll be very very cool and you probably going to save my day.

Copy random part at the extremity of the previous one 2019年11月7日17:28
Hello !
I'm new to this forum and i'm actually diving into Houdini since two months.
Now, i'm pretty close to finish a HDA about Subway generator.
I'm come here because i'm stuck and i can't find solution, so i hope that i could directly find help here.
Let explain my issue :
I've got three subway part, one large, and two others, much more smaller.
I've got a parameter which copy part based on the bbox of the part selected.
What i want to do it's that for each copy, it choose randomly an entry in my switch, to have a mix of differents parts and not just a copy of a same part all along (which is what i've got now, with a basic copy).
So it has to check for a part selected, the bbox of the previous one selected to determine how long it have to be translate to be placed at the extremetity of the previous one.
I hope, i've been clear enough. I'm really stuck about, so if somebody could help me with that, it'll be really nice !
