Unnecessary Dark Lines And Spots Are Visible In Viewport

Hello, Team
Currently I am using free trial, as I have to figure out few things.
Whenever I try to import mesh from 3ds max (2023), a problem arises.
Meshes are not proper and Dark sports are visible in it , There are unnecessary Dark Lines are visible

Could you share a link to an uploaded scene showing these issues? We’d like to take a closer look at them.


Shapespark is focused on web 3D scene presentation, so it optimizes the scene geometry by default to reduce the download time and memory consumption. For your scene, having very detailed geometry, the default optimization settings are too aggressive. You can try disabling Meshes auto-simplification in the Objects tab, and increasing the vertex position precistion: Shapespark releases - #161 by wojtek
