i’m currently working with Geospatial creator, im trying to make a portal that i made to stay at the place, touching the surface but it fails to stay at the place (only altitude, longitude and latitude are in the place), but i cant make it accurate because there is no VPS in the place the object is, any tip to make the object anchored to the surface?

I tried without using geospatial creator and using the plane detection, but because the object is big, the arcore tracking fails, i think is because the fps drop bcs the object, because i tried with smaller objects and it works perfectly, any tip for making it work with geospatial creator or with plane detection
