I have colored my model in Vertex Paint mode, but it loses all coloring once I switch to Render. How do I go about making the color show up when I render it?
In object mode select the object that you would like to color, then add a material to that object. In the materials options panel, scroll down until you reach the Vertex Color Paint checkbox.
Once you check that, then all the color you add in the Vertex Pain mode will be rendered.
