Now let's paint. Go to polypaint tab on tool menu and click Colorize. In the Color menu choose a color of your choice and click FillObject button. This will add a base color to your object. Change the stroke to Spray, go to brush tab and under Auto masking enable CavityMask. Chose a color and start painting. You will see how your base color will remain under your paint as nice details. That is because cavity mask is enabled. You can play with cavity options and cavity mask curve to see the diferences. With more complex geometry you get more details thanks to cavity. You can get very nice results here and to make very detailed texture. At the end your model should look like fig 14F.


Ok now go to Texture Map panel and you will see several options here. You need New from polypaint for now. Click it and the texture will appear here. Then click Clone texture button. Go to Texture menu and you will see your texture there. Click export and save the file.

Go to Masking tab in Tool menu. Many options here too but you need Occlusion intensity slider and the Mask Ambient Occlusion button. Get the slider to 5-6.5 or so. Higher values get higher time to compute but deeper occlusion.Wait a bit and then press the Mask Ambient Occlusion button and see what should be in fig.15B. Go back to texture map tab and this time click New from Masking button. Repeat the steps again, clone your map, go to texture tab and export it. In masking tab there is Mask by cavity button. Optionally you can press it and generate a cavity mask. Then in texture map tab you can press new from masking and get a nice cavity mask too beside the occlusion one. But this is an option only if you want more details in your texture after combining all maps in photoshop.
