Object Mask problem
Hi guys, I have a question, i try to used Objects Masking with dash, but it's doesn't work, do you know why?
I put a scatter object on selection on my floor, and pick the house on object masking, but nothing append, the snow still applied everywhere in my scene

Hey @Awening 🙂
I would think that you need to increase the Distance parameter a lot to see any difference 🤔
And maybe right click and invert it to get the results you are after
And keep inside and optimize for curves should not be checked as you are not using a curve👍
Maybe this helps?
Oh I know why........
It was not an object, my house is a blueprint
So i can't put it like that, any solution to make it works with blueprint ?
but the solution is working !
Easiest would be to maybe just draw a spline around the house and use that instead I think
But maybe @spatiotemporal have any good insights here on using BPs as an Object Mask?
BPs work, but object masking has a peculiar way of working(mostly for closed objects), so use proximity masking instead
Is it possible to scatter a blueprint on a path scatter?
the meshes will be sampled from the BP, but it will not actually be the blueprints themselves that will be scattered.
that will come next year BPs cannot be used with
Instanced Static Mesh
so if you have lights or logic in your BP it will be ignored and just the meshes themselves will be usedMy blueprint is only like that:

But when I try to display this blueprint on the scattercurve, it's not working 😞 I think I have a bad process @spatiotemporal
do you have any errors in the output log?
its a dumb example, but it should work fine, this is just a 3 staticmesh BP:

oh it's weird i just restart unreal and it's working now
thanks you so much!
if there's any problem next time, make sure to open Output Log first, there might some clue there and we can work from that
any time 🙂
