I’m happy to give more detailed feedback:
First of all, the sheer quantity of information is great and since it’s well structured (and the layout / type setting looks gorgeous) you can jump right into any chapter that you’re interested in.
The most important read for me is the workflow going from blender to Substance Painter and back again. This always cost me a lot of time and requires experimentation and not a lot of other tutorials tackle that subject. Had I read the “It Is Necessary To Have A Material For Each TileSet” Tip earlier, I wouldn’t have spend a whole night shouting and curisng at my laptop.
I also found the lighting chapter (4.4) to be very helpful. Somehow I never found good guidance on lighting, so I learned by experimentation and often end up with overly complicated lighting set ups. It would be great to see a tutorial in the future that focusses on lighting.
I also found some new tools (F2 looks like something I should have used ages ago), the same applies to some of the hotkeys and other tutorials - very helpful.
I found it quite surprising that you chose a document size of 4096px. I usually set the document size to 512px or 1024px and export at a higher resolution (but I guess you need the resolution to paint all the details). Can you give a number of how many materials you have in your scene(s)? Dividing your scene into multiple .spp files now seems like such an easy trick that I should have used before.
I am thrilled to hear you work on a video game project next, can’t wait to see how that turns out!
