How to hide shadows

[bamiendev]

I have hidden the materials by:
setAlphaMode("MASK")
setAlphaCutoff(2)

How to hide shadows of all set materials:
setAlphaMode("MASK")
setAlphaCutoff(2)

Don't hide the objects like that, find them in the hierarchy and set their visibility to false. Than their shadows should disappear.

Aaa here is more api of three.js, it's too complicated for me. I need help, please help me

Use something like:

const mv = document.querySelector("model-viewer");
const sceneSym = Object.getOwnPropertySymbols(mv).find(x => x.description === "scene");

const model1 = modelViewer[sceneSym].children[0].getObjectByName('model1');
const model2 = modelViewer[sceneSym].children[0].getObjectByName('model2');
const model3 = modelViewer[sceneSym].children[0].getObjectByName('model3');
const model4  = modelViewer[sceneSym].children[0].getObjectByName('model4 ');

model1.visible = false;

and so on, you just need to find the path to the correct meshes... cant give you exact code because i dont know the structure of the model

Btw this is code from some older project, not sure it works 100% but should give you an idea how to do the thing you want to do.

is the same type of code i use, is working, i mean it's hide the object, but is still display the shadow, if anyone have an idea ?

Ahh I forgot to add this... you need to update the shadow after you hide/show objects.

modelViewer[sceneSym].updateShadow();
modelViewer[sceneSym].queueRender();
