[Vuforia] Object Shines When I Move Away The Camera From Image Target

Hello everyone,

I am working on a project with Vuforia SDK which is an augmented reality platform. The problem is, i have an image target object and when i show the camera to this image target, a 3D object appears. When i move the camera away from the image target, 3D object’s brightness increases. This situation occurred 5.4.0f3 version of Unity. I had no such problem in the previous version which was a version of 5.3… How can i fix this brightness. By the way, I have no light object in the scene. What added in new version and this happened? Thank you for your answers.

Any idea?

What material/shader the object has? Is it the same with Unlit material?

Maybe screenshot help also…

Hello,

Here is the screen shots of object:
