How to remove these black stripe when using depth-of-field effectComposer?

[lucid falcon]

I try to use dof effectPass but I find that sometimes there are some black stripes exist in the scene, if I remove this post processing then the stripe will go, and there is no light can cast shadow. why these black stripes appear and what should I do to remove them?

what does the effectcoposer code look like ?

try adding "frameBufferType":THREE.HalfFloatType into the composer constructor

this looks like NaN propagation - a given pixel is rendered out as a nan and then this value spreads due to blur. Are you using any custom post processing effects?

[lucid falcon]

no other processing effect,I just add a button on the page to determine whether to use it and not all models have this issue, I tried other stage model and looks fine. The confusing part is sometimes those black patches will twinkle even if I didn't control my camera or other thiings in the scene

const bokehParams = {
    focus: 1.0,
    aperture: 0.00005,
    maxblur: 0.01
}
const bokehPass = new BokehPass(scene, camera, bokehParams);

https://threejs.org/examples/#webgl_postprocessing_dof
didnt find the type in constructor

Oh you are using the three js composer i thought you were using pmndrs/post-processing when you said effectpass .. Ignore that statement then

[robust tiger]

Yea that definitelys eems like NaNs... idk too much about the dof field pass to know what would cause it

[patent frigate]

if possible try pmndrs/postprocessing

use code from here as reference https://github.com/pmndrs/postprocessing/tree/main/manual/assets/js/src/demos
