I have been making something similar to this tutorial: https://docs.zap.works/studio/projects/step-by-step-augmented-portal/
As a result, the content I uploaded was about 5mb (I kept the png images as small as possible). And there were only about 8 of them.
Do you have any tips on keeping content as small as possible for download?
Also, if you have tips for 3D models and bone animation, please share that too. I will move on to making 3D content very soon.
