Problem with Dataprep and rendering translucent materials at distance.

[MrRooTMe]

Hi,

Im trying to use dataprep for a massive open world game, and i have a problem with glass on distance.

when im importing a building using dataprep with glass on a point far away from the center point of the world (0,0,0) the glass appears to have some visual cluttering (image below).

after tons of testing the problem appears to be the distance between the glass and center world + datasmith usage + opacity at 0.5 value.

if im not using dataprep at all in the project and im making a simple glass material everything looks fine.

how can i solve it? i really need to use the dataprep for my imports…

You are importing datasmith files from which DCC?

Sounds like you could replace the glass material you get from dataprep by a more simple one if that works. Else get the model closer to the origin: in the original DCC or in UE.
Is the distance to origin on the transform or on the position of meshes’ vertices?

You could also try to enable High Precision Tangent Basis on the static mesh of your glass.

You could also share a udatasmith file with just the window so we could take a look at it.
