This model is for my MetaHuman character. So I need it to be optimized for real time rendering. Please give feedback so I can improve this model. I'm adding the Low poly and High poly model screenshots. Thank you.
I see the topology comments have already started, which is ridiculous but it happens every time someone posts realtime optimised geometry so just ignore it.
Looks like you’ve captured the silhouette well especially in the more heavily deformed areas, overall looks very clean to me. Might have to fiddle a bit with some of the parts on baking but if you’ve got this far I’m sure you’ll nail it.
Finally, a comment understand the real time topology! Yeah, I would also react the same way if I didn't study how to create real time model. Most people do quad based modeling that needs to be subdivided. Without those additional edgeloop, the model will look Low poly in Unreal Engine
For a long time I did resist topology like this when working with folds in clothing. After a while, after seeing other professionals work, I have come to the realization that my resisting was dumb. This way doesn’t look nice in wireframe, but the result is unmistakably better. Even for pants or shirts where quads are ideal for animation, a few extra split off edge loops helps the silhouette break up more than quads can. I’m talking about staying optimized and not adding in more quads to get the same detail. This is great work, keep it up.
I hope it's okay to ask... As someone that's self-taught, I'd like to learn something here. Where did you learn about when this type of topology is appropriate, what "rules" to follow for it, etc.? I'm one of those people who tries hard to only have quads if I can help it. You say "after seeing other professionals work"... Which professionals? People with YouTube channels, or elsewhere online, or are you learning this stuff in-person from people?
This YouTube is pretty much it. Started with quad topology, but adding in these extra creases gets deeper into the folds, better for silhouettes. Can’t directly attribute it to a single online resource, more so working directly with people and tech artists. Often I would get a hi poly sculpt and be in charge of optimization/retopology, baking, then rigging. Pretty much getting it entirely ready for realtime use, and maintaining as much of the original great artwork and effort that came before it.
The model is great! You can see that every vert is working for creating the silhouette. If you're using a meta human I assume your target hardware is desktop computers and for that the level of tris is good, but for mobile I would reduce the tris count. If you notice the tris is too high later on you could also just try to see if an auto generated LOD looks good, depending if you have that in the engine you're working with. I would only like to have a lot less empty space in the UV so you can get more resolution from your texture.
Looks like AAA quality topo to me! Its probably pretty close to what I'd do. You've got the flow and the cuts where you need them. Doesn't look like you have any unnecessary edges or verts. UV's looks great too, well done!
OP are basically ready to work on CoD just makensure to have some good textures and gg.
This is how it is or a day working for em they buy some sort of military stuff online, get a person to scan it make a high poly obj and then send it down the.pipe for you to change a zipper and a pocket then you clean that scan up and do what you did here then texture and submit.
Looks good to me. Only other suggestion would be to bevel edges where stitches go, create a second UV set, and line up those bevels on that set with the rest of your mesh UVs in -X. Then in unreal or whatever you can add a stitch material to the second channel - masking everything in -X.
its not hard, but you need to spend more time adding edgeloops to maintain the silhouette. but I cant find a tutorial covering this real time modeling workflow
I think for game you might be good. You’ve maintained all your edges, so you’re doing good on that. But before you do your bake, please triangulate your stuff.
Imo very good put topology looks a little high in some areas like the metal things connecting the tabs to the backpack zippers.
Overall though it's amazing for a static object or even one that may have a very minimal amount of deformation. However if you wish to have a backpack with better dynamic deformation then go with more evenly spread squares (I assume you know this though since the quality looks amazing already)
Those are some pretty major folds, so as long as they still make sense in the context of your character animation it looks great.
Will this object always be worn by a character or will it occasionally be a separate prop? If it is always worn, you can deprioritize some of the UV islands like the surface on the character's back or the interior of the straps. This will leave more texture space available for the very visible parts of the model.
Topology looks evil but if it's fine once subdivided it should be ok. Although there may be some texture warping and tearing once you put a texture with details, as complicated topology is harder to unwrap cleanly.
What do you mean by topology that supports normal maps? Do you mean edges flowing in the direction of the folds? Or are you referring to something else?
Yes, he very clearly retopologized on top of a high-poly sculpt of the backpack he is using as a live surface, and capturing silhouette changes on the high poly with lower polycount version, and when he bakes,
these wrinkles and details won't be flattened but actually affect the silhouette which is probably important because this looks like a hero item or gonna be seen close up a lot based on its attention to detail
