Now let's paint. Go to Tool > Polypaint and click Colorize (Fig.14a). In the Color menu choose a color of your choice and click Fill Object (Fig.14b). This will add a base color to your object (Fig.14c). Change the stroke to Spray, go Brush > Auto masking and enable CavityMask (Fig.14d - e). Chose a color and start painting. You will see how your base color will remain under your paint as nice details. That is because CavityMask is enabled. You can play with the cavity options and cavity mask curve to see the differences. With more complex geometry you get more details thanks to cavity. You can get very nice results here and make very detailed texture. At the end your model should look like this (Fig.14f).
Ok now go to the Texture Map panel and you will see several options here. For now you need to go to Polypaint > New. Click it and the texture will appear here (Fig.15).Then click Clone Texture. Go to the Texture menu and you will see your texture there. Click export and save the file (Fig.15a).
