test of obj with per vertex color

grabcad

Testing an object with per-vertex color is a straightforward process. First, ensure that your 3D modeling software supports per-vertex coloring. Most modern applications do. Next, select the object you want to assign colors to and access its properties or attributes panel. This is where you'll find the settings for vertex colors. Under the vertex color section, click on the add new vertex color button. A dialog box will appear asking for the color values. Enter your desired color in RGB format (Red, Green, Blue). You can use decimal values between 0 and 1 or hexadecimal values like #RRGGBB. Once you've entered the color, you'll see it applied to the object's vertices.
