Even on a uniquely textured model it often doesn't make sense to be welding objects together, though as we've already said, this is dependent on the model. Just as an example from a model of mine Welding the spokes to the rim and the center wouldn't make sense for a variety of reasons. While I agree that wasted space in a…
I'm going to disagree with the sentiment that the first example is the better solution whenever possible, in fact for games the second example is more often than not a better solution. It's highly dependent on the use of the model however. Deformation is only important on a mesh that will animate (and deform during…
I would agree with the comment by CrackRockSteady, it got to the point. The only thing I would like to add in here that noone have mentioned yet, is z fighting at distance. It wouldn't really happen with the particular mesh shown in the example, but it would definitely happen with thinner boxes. Its usually not so…
Oh, I absolutely agree with you that in the OPs presented case welding would probably be the preferable method. It's just that the OP isn't asking about his 2-cube example specifically, he used 2 cubes as a simple way to present his question clearly. His question is about welding vs. interpenetrating geometry as a general…
Yeah your example is a good case when the geometry should not be merged, for starters they're technically not considered part of the same surface since they're not carved from a single piece of wood. Referring to my previous post that mesh would fit my exceptions as (1), (2) and (5). Unfortunately, it's really not very…
@CrackRockSteady @Axi5 That two models was just an example, not specific models I've got problem with. Thanks for discussion, I didn't expect so many posts :) So it really depends on the situation and lead/client wish.
Id say it depends mainly on the model and your workflow. Think about how it would be constructed in reality and try to mimic that. For example those two cubes could be separate objects but it would make sense not to just have them clipping into each other, there would be a join where they're connected (such as welding…
