The title of this product suggests that the software used for the tutorials is - obviously - Hexagon.
Hexagon has a complete set of tools for UVmapping, so in my opinion these tools should be used, explained if needed.
Being asked to get UVmapper is just the same as if they had advised to get Lightwave, just to be able to follow the tutorials for Hexagon.
The second thing that put me off: starting to build some kind of cloth for a DAZzie - now, while certainly everybody has some kind of personal preference to model, in a tutorial I do not want to see any personal preferences (and if, it should be noted, like “... there is the normal way to do XY, but I prefer to do it MY way…”).
So (still building the cloth) when I see somebody doing this without using the mirror option - think of a noob to Hexagon, or even 3D modeling entirely - it makes me want to grab into the screen, and push the right buttons for the person who is misleading folks .
The same goes for pushing points to get the base for a more organic form (the dino), when there is the soft selection.
Please, do not get me wrong here: nothing against pushing vertices around - but if there are better tools for the job at hand, why not show them?
The person who did all these modeling parts - well, I strongly believe that he learned Hexagon himself while doing his modeling for this course (later he found the mirror option).
OK, then the issue about the white board, about finding it not needed to be more precise in his scribbling:
If I do not have the time to spread out my personal theories in public (getting paid for this, remember), why should I do it?
“... I do not have time for this!” Is the impression that first comes to mind watching this. The modeler even said this at one point where more work should have be done for a part of his show.
Anyway, there are more issues in this “course”, but I think that - this time - my answer is long enough .
