In this 2:44 hour long video you`ll see the process of creating a leather couch in Blender.
We`ll cover some of the general techniques such as 3d modeling, UV unwrapping, sculpting as well as material, light and render adjustments.
I will also show you how to create cushions with cloth simulation.

Together with the video tutorial you will be available two scene files with a 3d model.
1 file - Blender 2.8 + Eevee.
2 file - Blender 2.79 + Cycles.
Brush for sculpting, textures and all that you need to work, will be packed in the file itself. 


This lesson is recorded in version 2.79, but it can be performed in any version of Blender because in the video the focus is on creating the 3d model itself, not on parsing the tools. For the same reason, the lesson is suitable for people who have basic skills in the program.

If you want a more detailed overview of the process I suggest you check out this course:
