Daz Studio, Vue Complete 11, Photoshop Elements 11, Filter Forge, Artrage
The cavemen and mammoths were posed in DazStudio and rendered in Vue Complete ver 11. The render was brought into ArtRage where I painted the clothing, spears and birds.
In Photoshop Elements I duplicated the original layer 3 times. On the layer#1 (top) I used FF's Comic Stylize & weidness (opacitty darken 100%), layer#2 StevieJ's sketch black (opacity multiply 100%) layer#3 Smeary oil painting (opacity normal 42%) and layer 4 (bottom) is the original render...
Filter Forge is one fine app... Love it...well worth the money...
