Problem with " Positional Tracker " :(

hi ...
actually, " Positional Tracker " is an awesome feature for " image target " mode BUT ...

but I don't know why this happened really!
a bug ?! or my fault?



In some angles , the walls become dark !

 

Hi @Amin-

This is due to how you have your directional light setup and how your AR target is moving in the Unity Scene. I suggest that you try and inspect in the Editor mode how your AR objects are moving relative to each other and how they are affected by the camera perspective and directional light.

What is happening is that:
- with "First target" mode your AR Camera is the one that moves around the AR target.
- with "Positional Tracker" your AR target moves around the camera.

Tip: If you really want to use Position Tracker you can try to make your Directional Light as a child of the AR Camera so it always keeps the light angle that you want.

 

Hi @henriqueranj ...
Thank you for your reply
My scene is " baked " and making Directional Light as a child of the AR Camera won't work !


Actually , I found a solution after some tests
that's it :


unfortunately , in this method, you didn't have transparent material anymore !
