Use a shape key to increase, decrease or smooth desired features Nazar Noschenko on easy UV deformations
Character artist Nazar Noschenko gives us five tips for creating vivid characters in Blender
QUICKLY RETOPOLOGISE YOUR CHARACTER
Take an already retopologised model and edit it to proportionally fit your sculpted character. Next, add the Shrinkwrap modifier and choose your sculpt as a tangent object. Now smooth and move the topology to emphasise the details of your character.
Then apply the Shrinkwrap.
Applying Booleans in Blender can be pretty time-consuming, especially if you have more than two objects. To speed this process up install the Booltool add-on.
CHANGE THE MESH RESOLUTION WHEN SCULPTING
In order to reduce or increase the resolution of your whole mesh when using dynamic topology, change the detail type method to constant detail. Now choose the desired resolution and press Detail Flood Fill.
EASY UV DEFORMATION
When you UV unwrap your character the main features such as eyes, nose and mouth usually turn out much smaller in comparison to the other parts. Use a shape key to increase, decrease or smooth the desired features and then unwrap the model. Afterwards, delete the shape key.
TAKE CONTROL OF YOUR TEXTURING
Start with a skin tone, and then create separate images for the red and yellow parts of the skin such as face details, freckles, ambient occlusion and so on. Use the MIXRGB node to combine them. This way you will have way more control than if you were painting it all on the same layer.
