Hi everyone,
I have been attending D2 for about 4 years now. It is a great venue, with really nice vibe and one can meet a lot of artists. Literally from all over the world - last year, there have been around 400-450 professionals, this one is probably going to be even more, considering the venue will take place in much bigger space.There used to be a workshop a day or two upfront, and I was lucky enough to visit one, lead by the guys behind PlompMozes. Last year there was a workshop, related to Unreal. From what people told me, it was bit too technical.
The Total Chaos is definitely bigger one, and not so tightly related to archviz. Lucky enough to work in Sofia, so travelling is not a problem. Strongly suggest the full package tickets, since there are really some quite nice talks and discussions which go simultanously with the main room event. There is going to be workshop as well a day upfront, and I am definitely looking forward it as well. The venue takes place really close to airport, and there are at least 2-3 rally nice, big hotels situated in close proximity to venue. The venue was visited by around 700-1000 people last year, with talks ranging from modeling to VFX - archviz, automotive, movie industry and of course some coding stuff as usual.
There are several other nice events - in Italy, one called immersive "something" and in Spain.
