Hello NudeFan6,

Here is a process: To get a good result, load your g3f figure as obj and your genital obj in BS3D. Apply Torso map to G3F Torso and create a blank map 4096x4096 and apply it to the genital obj Paint with a plain color around gen obj on g3f in order to get a guide for your painting

Select your genital obj and move it slightly horizontally. As you certainly want the same amount of details, use the clone brush from the g3f torso to your map applied on gen obj Once done, you can reset position of your gen obj to see if it match perfectly Now, in brush tile setup, load your reference image, align it and paint to add details.

Your diffuse map is now ready.

To get your base bump map, save your diffuse, re import in the map tad, right click and turn it to greyscale Create a new map in the map tab, affect it to the gen opacity channel, go in opacity wiew, fill it with black and invert in the map tab. Opacity is done Save and re import your bump map and use the blur tool to make your spec map.

For all the maps, do not forget to do a "bleed UV seams" before saving. All the set is done now.

Hope it helps,

Best regards
