  1. hi guys, I am new in BabylonJS, and trying to build some PBR materials with special effects, for example "thin film iridescence" in BabylonJS. I am learning something about PBR-Material and building my own PBR-Shader. I built a basic PBR-Shader, and now I want to do something more with IBL(image based lighting) and hdr. For Specular IBL i need to use textureLod Function from openGL to load mipmap according to the roughness levels. I tried something, but i always get the error "ERROR: 0:51: 'textureLod' : no matching overloaded function found". hier is what i tried. in HTML file
  2. Folks, hi, again!!! I trying use BJS.DynamicTexture for draw in and next use in custom shader, but shader ignore geometry with shader material if i try set that texture as samplier2D. And do not generate any Errors (( If we switch off DynamicTexture or use simple Texture - all is ok. Sorry, i can't make this case in PG. Try show situation here: // var dataTexture = new BJS.Texture('/accel/static/i/fx/.../name.jpg',scene,true,false,0,function(){loadedTextures--;}); // its work var dataTexture = new BJS.DynamicTexture("dataTx",{width:2048,height:2048}, scene,fa
  3. Hey folks, first of all: thank you for this great forum. It came to the rescue a few times, now. So, thanks everyone, who's participating. I'm currently working on an idea, where I would like to project a spherical panorama texture to a mesh from inside (meaning from the viewpoint). Similar to a standard VR-Viewer, where the texture is mapped on a sphere from inside. But in my case I would like to map it on the actual scene-mesh which I get from 3dsmax. Now, I know, that I could create the UV's or bake the texture in 3dsmax, but I want to switch between two camera positions and theref
  4. Hey Folks! In our scene we have some images with transparency on quads. The transparency is just used to mask the silhouettes of the image, so we have no larger half- transparent areas. So far we used the default shader for this, which produced nice silhouettes. All these Objekt are registered in a shadow generator from which we extract the shadow map an pass it in a custom shader. After writing our own shader for the images we ran into a problem: The shadow generator now only takes the quad into account, not the transparency of the image. Therefor the shadows of
  5. Hello, this is my first post, but visit the forum for a while and am thrilled. :-) I'm currently working on a Babylon project and I'm using a CustomShader (ShaderMaterial) for the Meshes. Now I wanted to use mesh.dispose(); and mesh.material.dispose(); to remove the textures, but it does not work. Whenever I check the size with scene.textures.length, it becomes more and more. What helps?
