So i have some images with transparency but i want to use them on an opaque mesh
after i do material.transparent=false & material.needsUpdate=true
there’s still some depth issue present which is causing some glitches
screenshots:
material.transparent=true + material.needsUpdate=true
and when i make the materials opaque
material.transparent=false + material.needsUpdate=true
opacity is 1 and alphaTest is 0 so they are not causing the issue
is there any step missing to make it behave like a fully opaque material ?
@donmccurdy is this a bug ? should i report in repo ?
Even after i remove the images and material.tranparent=false
, it still has some transparency
So the problem comes when using glb but not when manually creating the planes Geometries w/ textures
Transparency on
Transparency off
trying to setup jsfiddle but it does not seem to load glb from github raw url ,
update: code sandbox loads glb
here’s the demo Transparency issue - CodeSandbox
@orion_prime GLTFLoader will set .depthWrite=false for any materials that are transparent (use alpha blending, in glTF terms) in the GLB. If you’re changing them to transparent=false you will want to set .depthWrite=true I think.

yes!
depthWrite fixes this problem
based on this issue 17706
@donmccurdy also when the model loads the transparency looks perfect from all angles , but after i toggle transparency off and then On, i’m seeing this pink planes in the transparent region at certain angles
can that be fixed ?
I’m not sure what’s happening there… it sounds like the material settings are not quite the same before and after the toggle?

i was traversing the scene and setting depthWrite and transparency
and the ground projection mesh was also affected , that was the issue i guess
I added a separate group to traverse and it seems fine now
