take the steam punk challenge. Mike was going to get us all to swap models - but ditched the idea because of the software issues. Obj are rubbish as a file type if you need the to have separate parts to it. Mayas separate tools does not always work and you lose any group/laying with them. Also hardware wise I`m better my quad core pc could take the heaviest of models but I`m betting that others could not even open some of the files I work with, without crashing maya. I`m not trying to be like "My PC better than yours" or anything but thats just the it is sometimes. The only way a challenge like this could work is if there was a lot of restrictions on it. One of the reasons I like the challenges here is because they are quit relaxed here on the rules.
