Hi! Thanks for your interest. The shape quality of the input mesh should be sharp enough. The surface of your input mesh is too uneven. I recommend using outputs from methods like 3D reconstruction or SDS (like Dreamcraft3D) as inputs for our model since these methods usually provide sufficiently high shape quality. As for feed-forward methods like LRM, their output quality is still not high enough. In my own attempts, they mostly failed.

but there is an 800 face limitation here though?
