After a long wait, I finally decide to practice some sculpting using Blender. As usual, Blender has some solid base in its own tools, lacking a direct way to do most of the advanced features, that have to be recreated with different tricks. I was impressed by what it's possible to achieve in Blender's Sculpt Mode, yet Zbrush looks more complete when focussing on the sculpting itself. Mainly I tried to understand if and how the sculpt mode can practically help the creation of a game in UE4.
I sculpted a simple skull (and I'm rather happy with the result too!) and that I retopo a the Low Poly version directly in Blender and baked Normals, AO and displacement from the High Poly. The result lack some quality and polish, a proper retopo would increase the quality, but overall it looks like a usable tool for a Blender to UE4 workflow.
Contact me if you have any questions! Good sculpting. :D
