ProBuilder enter UV coordinates directly?

JoeStrout · May 8, 2020, 6:24pm

I’m in a situation where it would be really handy to be able to type in the UV coordinates numerically — for example, on a particular face I want them to go from 0 to 12 and not almost 0-12 like -0.023 to 11.97842 or whatever.

Is there any way in ProBuilder to just type in the coordinates I want? Or, having gotten them approximately correct, some button I can press to snap them to round values?

If not, how would I go about making such an extension?

Hi again On PC, when you are in the “UV editor” in probuilder, hold control to enable snapping. This applies to the full uv coordinates, a single vertice, basically everthing you can do involving movement within the uv editor. If you’re doing atlasing (not sure if you are), then it can make a huge difference working in 128,256,512, 1028 etc for this snapping to work best.

As for entering in numbers manually, I don’t know of probuilder having this ability, but I’ve heard of it being done via scripting with exported meshes. Hope this helps!

To get started on an extension to do this, a good starting point would be the vertex position editor.

github.com

Unity-Technologies/com.unity.probuilder/blob/master/Editor/EditorCore/VertexPositionEditor.cs

using UnityEngine;
using System.Collections.Generic;
using System.Linq;
using UnityEngine.ProBuilder;

namespace UnityEditor.ProBuilder
{
    /// <summary>
    /// A simple line-item editor for vertex positions.
    /// </summary>
    sealed class VertexPositionEditor : ConfigurableWindow
    {
        const int k_MaxSelectableVertices = 100;
        Dictionary<ProBuilderMesh, VertexEditorSelection> m_Selection = new Dictionary<ProBuilderMesh, VertexEditorSelection>();
        static Color s_EvenColor;
        static Color s_OddColor;

        Vector2 m_Scroll = Vector2.zero;
        bool m_IsActive;
