Re: tutorials for skecth up
I think this was exactly my point, dalomar…I probably should have just left it alone!
But since I’m going through the same thing as victorincon with learning how to use vray4SU, I understand how getting a firm grasp on this can be discouraging at times.
You’re absolutely correct; Vray IS very complex. However, after trying several different systems, I can confidently say that there really is no “silver bullet”. But for my purposes, SU paired with Vray is pretty close! It will take some time to study and learn how to manipulate all the controls skillfully and for many users, myself definitely included, that can mean a significant commitment to get encouraging results. Like you, I am also an architect and have very little time to allocate towards becoming a “software expert”. I’m actually just starting to demo this with hopes that I will master it well enough in 30 days to make a convincing presentation to my principal. I really want him to provide me with a license, so I guess that’s my motivation.
You’ll probably discover that there are a few global setting that you may never have to worry about too much, however there can be many scene-specific variables that must be accounted for in order to produce really good renders. Again, there is no “silver bullet”. I’m finding that you just have to dig a little (sometime a LOT) to learn how to make those adjustments on a scene-to-scene basis…now and then, even outside of these forums (gasp!). 
Just out of curiosity, victorincon, is there something in particular that you’re trying to learn that you were unable to uncover in the manual or from searching these forums? Like dalomar mentioned, there are many knowledgable people here with a great amount of valuable experience that I’m sure are willing to assist you with your questions. Obviously, I probably can’t help much since I’m still very green, but if you could describe exactly what it is you’re trying to accomplish and the problem you having with achieving your goal, I’ll bet there’s someone who would be happy to help.
I can tell you that almost everything I can do with this so far is a product of reading, searching, and more reading. And naturally when learning anything new, there’s a dash of trial and error thrown in for good measure. For me, the last week has been comparable to learning a new language. However, with some patience and persistence, I’m certain your efforts will pay off. Hopefully, mine too! Good luck!! ;D
