How to upload 3d objs with Nomad to Spark AR

Hi! :smiley: I am new to Nomad Sculpt and Spark AR and I was wondering if anyone can teach me how to upload 3d objects in Spark AR. Well, I know how to upload, it just doesn’t work for me I tried every export options like gitf and obj. but the file doesn’t work on spark ar. I don’t know what I am doing wrong,( for context, I am thinking of uploading small 3d objects like eyelashes or small 3d hearts etc.) can anyone please help me? Thank you!
