  1. Hello, I have to control depth of meshes with alphaIndex in my situation. but when meshes are over 10, rendering gets strange. need your help. thanks.
  2. The new GlowLayer doesn't seem to work when an opacityTexture is applied to a mesh that also has an emissiveColor. See PG When opacityTexture is commented out then the glow returns. Is this a bug or just a limitation of the technology at present? Or have I missed something?
  3. I've been experimenting with the ability to use the opacityTexture with materials. And I have a couple of questions. First, what is the functionality of the opacityTexture in BJS. In the PG demo of fire, it appears to be acting as an alpha map that gives a general shape of the flame. Candle stick However, when I try to use the same flame and alpha map on a simple plane in a playground - I just get the square image of fire Simple plane Why? Does the use of .opacityTextures require the fireMaterial script? If it does, that is not indicated in the docs. Secondly, I tried using the same two textures in Blender - see result below. A simple plane has one material with two textures - flame and opacity.- and as you can see both have an impact on what is rendered. However, when I export the plane to .babylon I get this curious comment: Looking at the .babylon file the material only contains the flame texture - no reference at all to the opacity texture used. What does that mean? And how do I export these alpha map textures from Blender ? Edit: I have the opacity texture exporting now by changing the value of the "alpha" in image below to 1. But I still get the warning message and the result viewed in the sandbox is just the square plane with the flame texture cheers, gryff
  4. Hey all! I'm having a hard time with opacityTexture. Hair just seem to "flip" somehow. I'v attached some images so you can see the difference. Any idea what might cause that kind of behavior? Code: var material2 = new BABYLON.StandardMaterial("texture2", scene); material2.diffuseTexture = new BABYLON.Texture("data/models/hair.png", scene); material2.opacityTexture = material2.diffuseTexture; material2.backFaceCulling = false; hairModel1 = newMeshes[1]; hairModel1.material = material2;
  5. I discovered babylon.js last week, and its very good mostly Lets me finally take a crack at game design, since full environments like Unity are too daunting for me. I started playing around with it, and one of the issues I encountered was that imported meshes with an opacity map are not displayed correctly in my scene, the meshes behind 'bleed through'. I unfortunately cannot setup my scene in the playground since it loads .babylon meshes and is enveloped by php/mysql already, but I have a screenshot: As you can see, I circled two areas where the bushes in the background bleed through the bush in the foreground. Also a bit to the right more foliage is bleeding through, which I didn't circle. Oddly enough the grass, which obviously also uses an opacity map also doesn't suffer from this. But the grass is just a Plane, not an imported mesh.
