Transparent Texture Issue With Instancedmesh Questions Three Js Forum Hey, so, i have an instancedmesh object with thousands of semi transparent textured cubes (see pic below). from certain points of view, meshes can completely hide other meshes, even on the parts when they’re supposed t…. If your mesh textures have areas of complete transparency (rather than partial) you should be able to use material.alphatest to discard unwanted fragments without artifacts.
Transparent Faces In Three Js Questions Three Js Forum I have instanced objects spread around, along with individual non instanced transparent boxes, and you can see that at certain angles the instanced objects are not visible or they are: any tips or thoughts on how to handle this?. I’m facing some issues with a custom shader and instancedmesh. i made a fiddle to replicate my issue. to make it simple, this instanced mesh are moving around and from time to time one will be in front of the other, and when this happen, depending on the render order i think, the opacity won’t work correctly. Let me show you two different approaches to achieve good looking transparency of transparent sprites (like grass, leaves, and such) in threejs. we will be rendering a big grass patch to demonstrate them. Unfortunately, this kind of transparency issue is hard to tackle. setting depthwrite: false is right but you have to sort instances per frame based on their distance to the camera to improve results.

Have a question about this project? sign up for a free github account to open an issue and contact its maintainers and the community. I release a plugin about end of the week that will cover this sorting issue with a sort option for instances, the api is on top of instancedmesh but a bit different as you have regular mesh objects in your scene.

I’m using a custom shadermaterial to make their edges black and to control the transparency. when i set all the boxes except one to alpha=0, the one that’s supposed to stay visible has only three sides visible, instead of six.
