    <p>Your loaded object has geometry (along with its vertices, faces and UVs) and material. Create ShaderMaterial that combines the textures in some way that suits you and create mesh with geometry from loaded object.</p> <p>Use ShaderMaterial and set both textures as uniforms, and then blend them within shader.</p> <p>So, you make ShaderMaterial:</p> <pre><code>var vertShader = document.getElementById('vertex_shh').innerHTML; var fragShader = document.getElementById('fragment_shh').innerHTML; var attributes = {}; // custom attributes var uniforms = { // custom uniforms (your textures) tOne: { type: "t", value: THREE.ImageUtils.loadTexture( "cover.png" ) }, tSec: { type: "t", value: THREE.ImageUtils.loadTexture( "grass.jpg" ) } }; var material_shh = new THREE.ShaderMaterial({ uniforms: uniforms, attributes: attributes, vertexShader: vertShader, fragmentShader: fragShader }); </code></pre> <p>And create mesh with that material:</p> <pre><code>var me = new THREE.Mesh( my_loaded_model, material_shh ); // you previously loaded geometry of the object </code></pre> <p>You can put simplest vertex shader:</p> <pre><code>varying vec2 vUv; void main() { vUv = uv; vec4 mvPosition = modelViewMatrix * vec4( position, 1.0 ); gl_Position = projectionMatrix * mvPosition; } </code></pre> <p>And fragment shader that will actually do the blending:</p> <pre><code>#ifdef GL_ES precision highp float; #endif uniform sampler2D tOne; uniform sampler2D tSec; varying vec2 vUv; void main(void) { vec3 c; vec4 Ca = texture2D(tOne, vUv); vec4 Cb = texture2D(tSec, vUv); c = Ca.rgb * Ca.a + Cb.rgb * Cb.a * (1.0 - Ca.a); // blending equation or wahtever suits you gl_FragColor= vec4(c, 1.0); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
