The main difference betwixt high and depression polygon modeling is exactly what the name implies: whether y'all use a loftier number of polygons in your model, or a low number.
However there are other things to take into consideration when deciding the detail and poly level of each model. About notably the textures you use in your materials.
This article will become into the differences, the pros, and the cons of each blazon and why you should make up one's mind which technique you wish to apply before you start modelling!
Should I Use High or Depression Poly?
The answer to this question is highly dependent on how you intend to use your model one time information technology's done.
If you are making a model that you intend to employ in a game, or render in a real time engine such equally Unreal or Unity, then you demand to exist heavily using low poly modeling.
Low poly models tend to use less computational power to render, so they are more suited for these kinds of engines that need to rapidly calculate how your model reacts in the virtual environment.
However if you're producing a high quality render, peradventure for marketing reasons, and then yous will often employ high poly modeling.
If y'all are producing still shots or even a video, the amount of fourth dimension it takes to render a frame is more or less irrelevant. Because of this yous can produce models that are more difficult for your estimator to summate, considering the finish result does not need to calculate any more once it's completed.
Pros & Cons Of Each Style
The primary strength of low poly modeling was briefly touched upon in the last section: ease of use. The lightweight size of these models can brand them easier to work with if you're doing a lot of on-the-wing rendering(common with game development).
This counts for both you and your workstation too. Low poly models tin be a lot easier to load, view, and edit on your auto. This as well by and large leads to quicker return times.
These models can also be easier to work on from a modeling perspective besides. Information technology'south by and large easier to brand edits to a less complicated mesh, compared to a mesh with millions of polygons.
The downside of low polygonal meshes is that information technology'southward difficult to achieve the high level of detail you may desire in your finished product. Because you are using fewer polygons, you have less geometry that you can dispense into certain shapes. This ways things like creases on apparel cannot exist made in the mesh.
However at that place is a style around this. Using normal maps and height (or displacement) maps tin can simulate the style lite behaves on the object in the return. This can requite the illusion of details being on the model directly.
If washed correctly, this tin can expect just as skilful equally modeling in detail.
The final thing you need to consider when making a depression poly model is the texture yous use, such as normal maps, only only equally importantly the lengthened maps y'all use to add colour to your finished mesh.
The size and number of images you're using in your texture maps just add together more resources that your PC needs to calculate. And remember, low poly is great specifically considering information technology tin exist less resource-heavy!
For this reason you will rarely want to use images larger than 4096×4096 in your low poly models, and may want to condense multiple maps into a single texture sheet (a unmarried image that contains all of you maps that will fit onto a UV unwrapped model).
This is specially of import if y'all are making a game for a mobile phone, every bit they have much less computational ability compared to consoles or gaming PC rigs.
A farther do good of depression poly modeling is it helps you practice your optimization skills, and then even if you choose to specialize in high poly modeling instead, low-poly techniques tin still benefit you throughout your career.
High poly modeling has its own pros and cons too. And they can be hands summarized as the opposite of low poly models!
You lot can get far more detail in your base of operations mesh, which tin let for far nicer models in the final render, at the toll of renders taking hours to consummate.
They tin besides exist harder to work with. If your workstation is using older hardware then working on the model can become a chore. Moving around the viewport becomes a slow process and making edits can accept a long time due to the density of the mesh.
You lot can also use images at very loftier resolution. And use as many images as you want for your materials, which can brand texturing slightly easier and give higher fidelity results.
On the whole, information technology'due south a skillful thought to familiarize yourself with both of these modelling styles as they both take their uses.
Fifty-fifty in the case of depression poly modeling, an increasingly popular way to produce them is modeling the depression poly base mesh, then making a clone that you add high poly detail onto.
From in that location y'all can use software such as Substance Painter to broil the high poly mesh particular onto the depression poly mesh as a normal map. The more you exercise this, the easier it gets.
This gives you a effect that is comparable to the high poly model, but with all the benefits of a low poly model! Merely note this requires proficiency in both modeling methods, and that's ane large reason why you lot should consider practicing both.
