Textures flickering when importing into 8wall

Hello, i’m using houdini to create some models and exporting to a glb file and uploading to 8wall.
all of the models are fine, except for this debris i want to add to some scene.
it’s textures are flickering. it drives me crazy!
what can be the cause?
added a video

it didn’t let me upload an attachment since i’m a new user, hopefully this work.
any help would be highly appreciated, it’s a really critical model for our scene!
Thanks!

If the model is from Houdini, there’s a good chance it’s overly complex and could be simplified without losing visual quality. Would you be able to send me the model via DM?

hey george, thank you for replying. ill send you the model, hopefully it’s not too heavy.
i’m a 3D Artist and it’s really not a complicated model just because it’s from houdini. maybe the way houdini exports glb is problematic
