Hi , for some reason i cant store attribute before simulation node to use?
Same geometry , same attribute , but after sim nodes it just doesnt work?
You may have confused using with storing ??
no , obviously i stored an attribute âTRUEâ before , just didnt show it here
âObviouslyâ one can type whatever one want into the name field of the Named Attribute node and if there is none shown then others do not know if they are also stored with the same name in the name field of a Store Named Attribute node.
Sometimes itâs exactly this⌠something one may have overlooked when working with something over some time and so showing here helps when other users do have a look.
Nothing is obvious from your descriptionâŚ
We canât see what came before the points on faces, we canât see what comes later in the sim zoneâŚ
⌠how are we supposed to know that youâre not setting the attribute later in the sim and then showing us a screenshot from a later frame?
With this type of question, the best response you can possibly get is âwho knows?â
Good luck.
Hi , heres the file simplified for the problem i encounter
Cantsotre.blend (1.1 MB)
from what i understand , i need to store this value per frame , but i dont know how to do that before the sim nodes
sorry , i attached a file now
From what I can see, itâs working as expected.
Your raycasting is not hitting the sphere so the âTRUEâ value is 0.
If you orient the rays from the raycasting node to +Z (0.0, 0.0, 1.0), then some rays will hit the sphere and youâll see different values.
Now, the BlurAttribute is too much⌠500 iterations for a 10x10 grid will make the attribute almost the same in all elements (and as itâs clamped, it will be 1 all over).
it is hitting the plane on frame 48, not the sphere, as for the blur attribute , i want to get a boolean value per mesh island , thats why i blur it
