Unity scene loading time optimization

Question

Hi, I have about 50 image targets in AR scene. Each image target has it own 3D model. Now it take a lot of time for loading in Mid-End android device (~45 seconds). How could I optimize my app to load faster?

Will reducing the image dimension help faster loading time?

Thanks.

Hi,

"Will reducing the image dimension help faster loading time?"

yes, high resolution images will impact load time drastically.

Also easyar uses image dimension if u do not specify image target size in your app so more image dimension should increase load time.

By the way you should test yourself to notice the difference.

What is the unit of ImageTarget Size? Is it Pixel or Real-World dimension of target (mm/cm/inch/m)?

I'm just copying this from easyar doc:
"The size of ImageTarget is set in json which will be loaded in the Load/LoadImage/LoadJsonFile/LoadJsonString method or calculated from image resolution automatically if not provided."

I believe it's centimeter.
