You should specify some more details like which platform you are exporting for and which texture type?
30 meg is the blank project size for android EC2 so you won’t get that small with any actual content. The biggest size dependency is texture size and number is textures. So you should specify that as well 
Do you have compress cooked content ticked?
There are some other tips on that link as well. A blank project cooked for ETC2 is around 50 meg with compressed content ticked for me
Hi! I’m working for a small interior VR and I have a package size issue. First it was 456 MB and now somehow reduced to 126 MB. And Can I reduced it to more like 30 MB.
Any help is greatly appreciated.
Using a blank project with no starter.
Packaging for Android ATC. Till now whatever I have done is all by watching Tutorials. And none of them are full or it might be a advanced tutorials.
Thanks.
s. I have seen this before and is it possible to reduce some more of the atc file size.
