To my knowledge, a good reason to merge objects into one is to reduce draw calls in a game engine. When rendering a frame, each object is drawn individually so having many objects can take longer to render vs having them merged into fewer objects will take less time to render. This probably becomes a concern mostly on weaker hardware like mobile devices or in very dense scenes. Other then that, if there's a practical reason to keep your objects separate, go for it. Just be aware of the tradeoffs.

I see few comments about merging into one object is better for games, and it's right most of the time (except for animated/moving parts). The critical point to remember guys, is to let the objects separated inside the modeling software, and THEN when you export into a game engine, you make it ONE .fbx/obj (which is one object in-engine). I always struggled about it, asking my self if i should split or not models in the modeling software : the answer is very often : NO (to keep better control).
@omri13244 жыл бұрын
You guys should have mentioned you're strictly talking about non-gaming production assets. Cause when you're making a game model you absolutely SHOULD merge it. Different objects means more draw-calls. one mesh = one draw-call. Therefore having each of your game models in a given scene be made of many separate parts = heavy performance issues.

One reason why you should separate your models is so that it's easier to calculate the mass of the model in physics situations, and especially the balance of weight. If your model is all one object, sure - you can still give the object weight, but if the object - say, a hammer - has a wooden shaft and a metal head, the physics simulation wouldn't be able to tell that the head is heavier, and your simulation wouldn't be accurate.

Hey guys, great video. I would say however having too many individual objects (especially in maya) can cause issues in complex scenes. In my studio we often combine geometry by material when possible. Obviously there are circumstances when this is not logical due to rigging, etc but this can dramatically boost performance in maya. We also lay out our uv's per material.

Well, I'm thinking of learning rigging in Blender; for my last anime-like character in the end I posed in Zbrush out of laziness but at some point I started to join the cloth with the body, thinking that it may be better to have them on the same UV island and not deal with UDIMs in Blender or whatever program. Actually doing so created an issue with SSS because there's a cut in the cloth (and also the body is cut where you don't see it so no need for more polygons there - and here's a new topic: "When to remove polygons on the bodies or not"), I had to kinda fake the SSS on that tiny piece of skin in the middle of the cloth lol I found an example of rigged character in Blender where the character has full body and separated clothes, I guess that's the way to go. It's kinda hard sometimes to find the right balance between the "game character" and the "industry production" workflows, especially when you're a hobbyist at home doing everything by yourself, not in a studio x) (oh and by the way you can see the result here : www.artstation.com/artwork/2xGy2a )

Very interesting. Somewhat unrelated, but here’s a topology question I’ve been trying to wrap my head around for some time now, so I thought maybe you’ll consider exploring this topic in detail to be an interesting idea. I couldn’t really find definitive answers anywhere. How bad (or good?) is it to have self intersecting/self crossing edge/face loops? Is topology with lots of those considered to be messy? Should they be avoided whenever possible and if yes, to what cost? Also are there situations when self intersecting edge/faceloops are actually desirable and should be actively pursued? Or is it maybe just not a big deal to even think about?
@Aussie.Owlcoholic4 жыл бұрын
From my experience it not a huge deal technically, but just for keeping things neat and tidy it can be good to not do this. Think of a wall with an extruded section. If you're really tight on poly counts then you could do a plane for the wall and a box intersecting it, but generally you would just inset and extrude, then separate if its another material. It means a few more Poly's (depending on the shape) but its clean and easy to read even in wireframe. One downside technically I can think of is some issues in baking the ao around the area but usually it won't be an issue. Likewise depending on the texture setup it can mean wasted UV space. If it was a huge issue performance wise then modular environments wouldn't really be possible since they often rely on lots of intersecting spaces.

When do you add more materials to an object? I believe with substance painter you can assign one material to everything and then paint in and sectively choose what parts get what detail, so often I feel there is no need for multiple materials. Is it simply for organization reasons or a UV map thing? I am unsure as ive never gotten a clear answer: When to use one material vs when to add another / use multiple.

I was actually thinking of a question along the lines of this topic. I will try to explain this clearly as possible; So say for instance I wanted to make a ship building system using modular pieces individually. I do think I would have to use the pieces separately so I would make the pieces in the model program and export them to the engine; but do I export the pieces with their own origins at their center or export them all sharing the same point of origin as the other pieces?

I get this when you work in Painter or in Maya, but what about when your mesh is ready to export to an engine? don't you want to merge smaller meshes? I can't imagine you want all these elements separate, because you constantly need to take care of these groups or parents and draw calls. Besides, it'll clutter your outliner in no time. I am talking about smaller assets mainly, modularity is always something to strive for.

That would depend on the project. If its a smaller prop that there will be a lot of it would be wise to combine. If its a huge castle its Better done modularly as occlusion culling would negate the issues of more draw calls. A whole building as one mesh might be okay in a top down game but 1st or 3rd person where it'll likely be higher quality and texture sizes would be bigger, separating walls and such means that it won't render the ones out of view which saves performance.

You should model it this way yes. But when it comes to exporting it to game engine no. It should all be combined into a single mesh especially in the case of the helmet they have shown in the video at-least. As another user pointed out this limits the amount of "draw calls" the game engine has to make, the lower the better the perf. Essentially the game engine pieces each frame together by looking for each individual object. You combine this helmet into 1 object it only has to do it once, verses uncombined 15 times for all the different components. This only makes sense if you're sending it straight to the game engine and not another artist who has to do animation or whatever.

This goes in a completely opposite way to everything I've learned about 3D assets and game engines for the past 3 years. The only application I can see for a mesh where everything's kept separate, is for high resolution, close up product shots. In every other instance, especially when it comes to using this mesh in a 3D engine, the mesh MUST be combined and one should use as fewer materials as possible (for example, for this helmet, one can use only 1 material instead of 5). This video makes absolutely no sense!
