There is a problem with the surface of the model？

[zihang]

After I open this model with vantage, there is always a black block on the surface of the model, which cannot be eliminated. There is no texture in the scene. The test scene is in the attachment。

It's hard to tell from the vrscene file alone, but maybe you have some triangles on top of each other there ?

If it's not that, can you send us the 3dsmax file too ?

Sorry, this is a file created from vrscene alone, there is no 3dsmax file, and I can be sure that the model does not overlap. And this black block will not move as the model moves

The issue only occurs around the center of the scene's coordinate system (0, 0, 0). We've seen similar shadow issues before, it's not caused by your geometry.

Is there a workaround for that?

Is there a workaround for that?

Can you try centering your object in its object space, i.e. so its center or bottom-center is at 0,0,0 in object space ?

We are working on a fix, but most likely it won't go in the next patch.
