Unity Particle System Interatction

January 13, 2023 - 8:43am #1

Hello, is it possible for Unity Particles to interact with detected planes in an AR application. I have a Particle System in Unity that animates water being sprayed in a circular pattern and I want the particles to appear on the floor (plane) in AR. I haven't discovered a way to achieve this and it would be amazing if that's a possibility.

IFC Prefab does not move with Target

Unity Editor
January 10, 2023 - 8:49am #1

I am creating a HoloLens application in which I track an IFC model that I imported from the Unity asset store using the IFC importer with an image target. However, the prefab does not move with me when I move the target. I have also added a cube for testing. This moved with the target when I moved it. I also tried to detach the elements from the prefab. Unfortunately, this did not work either.
What could be the reason for this?

Does Go 3 supports ground plane tracking?

scaling objects and orientation

Unity Editor
August 25, 2022 - 2:16am #1

Hello,

when I place .stl files or .ply files via the model creator in Unity, the orientation is sometimes different and the scaling is 0.1 / 0.001 respectively.

Even replacing by hand or rescaling leads to improper orientation. 

What is the optimal workflow here? How to set the orientation best in the model creator, stricly on the base plate??

There is even a diffenrence between .stl and .ply import ? (see attached picture)

Thx for help

How do I make the animation start from the beginning when I move away from the image target and back

Hello,

I am sort of new to Unity and Vuforia have been pretty good about figuring out my issues on my own, but this one has me stumped.

I am using Vuforia for my AR Camera and Image Target in Unity and how do I make the animation start from the beginning when I move away from the image target and back again?

When I move away from the image target and move back, the animation starts from where it was when I moved away from the image target.

I tried two setups using the midair placement components with the world origin set to the midair stage :
