solved Something wrong with my mesh

[howdoideletemyaccountpleas]

I'm creating a mesh from scratch but when I add a texture, I get nothing. The plane is simply white. Are my UV coords or normals not set up correctly for Babylonjs or am I missing something else?

 

import { Mesh, VertexBuffer, StandardMaterial, Texture } from 'babylonjs'

export default function CreateMesh(height, width, scene) {
  const mesh = new Mesh('TerrainMesh', scene)
  const indices = []
  const vertices = []
  const normals = []
  const uvs = []
  const startX = -width / 2
  const startY = -height / 2
  let index = 0

  for (let y = 0; y < height; y++) {
    for (let x = 0; x < width; x++) {
      vertices.push(startX + x, 0, startY + y)
      uvs.push(x / (width), y / (width - 1))
      normals.push(0, 1, 0)
      if (x < width - 1 && y < height - 1) {
        indices.push(index, index + width + 1, index + width)
        indices.push(index + width + 1, index, index + 1)
      }
      index++
    }
  }

  mesh.setVerticesData(VertexBuffer.PositionKind, vertices)
  mesh.setVerticesData(uvs, VertexBuffer.UVKind)
  mesh.setVerticesData(normals, VertexBuffer.NormalKind)
  mesh.setIndices(indices)

  let groundMaterial = new StandardMaterial("ground", scene)
  groundMaterial.diffuseTexture = new Texture("textures/earth.jpg", scene)
  mesh.material = groundMaterial

  return mesh
}

Hello! can you repro the issue in the Playground?

Hi guys!  First time posters... my treat (sometimes).    (I have no life/purpose)  heh

https://www.babylonjs-playground.com/#RGZPJH#7

I found problem, too...

https://www.babylonjs-playground.com/#RGZPJH#8

  mesh.setVerticesData(VertexBuffer.PositionKind, vertices)  // correct params order
  mesh.setVerticesData(uvs, VertexBuffer.UVKind)  // reversed params
  mesh.setVerticesData(normals, VertexBuffer.NormalKind)  // reversed params

I've made this mistake a few HUNDRED times, myself.    Party-on!

Wingnut, I don't know how many times I've looked through this code for an error. I've played with the UV mapping to go from 0,size and 0,size-1, started UV's from each corner, played with the normals.

I was so focused on that, I never would have found the param order bug. Thank you!

heh... MY pleasure.  I had to add 'BABYLON.' to many places... to make the playground run.  During adding BABYLON.VertexBuffer, the code gods gave us a gift.
