How to set the shadow resolution to avoid shadow issues?

Got a tiny scene that is a model viewer but the loaded models have some shadow artifacting on them I would like to fix

Here is the scene, Unity default cube in middle, not sure why shadows in Three.js are so sketchy

Seems to be shadow bias from my searches https://discourse.threejs.org/t/hello-i-am-facing-the-problem-with-shadow-stripes-on-model/18065/9

Only seems to happen with DropListener loaded models

by user 103054507105067008

These artifacts usually come from wrong settings for shadow bias. Shouldn’t matter if you’re loading these objects one way or another

It doesn’t affect the cube already in the scene which is at the top of the screenshot, I’ll keep playing with the bias but weird it only happens to Drop Listener loaded assets

I have shadow bias on URP set to the default that was in Needle Samples so not sure why its being weird and only for dynamically imported models

Does the dropped model contain lights?

Nope

I can share the model, was sent to Herbst a sec ago, I’m just dashing for lunch but i’ll be back

by user 103054507105067008

Btw latest version exposes the resolution. But as felix says these artefacts look like from wrong bias settings

Same here: lunch :slightly_smiling_face:

Why would it only affect drop listener loaded models though :confused:

by user 103054507105067008

It doesnt make sense yes

Are there two models ontop of each other?

I think i saw similar artefacts caused by that during our website dev

Where two planes/meshes where ontop of each other and instead of visible zfighting these artefacts appeared (both had the same color)

Nope it affects a character that is in the file that is animated too

by user 103054507105067008

It’s an avatar and a cube, both are animated

by user 103054507105067008

I will double check that the loading isn’t doubling up somehow though, could I console.log the scene to see that easily?
