When you need to tweak object dimensions, do it with regards to other objects in 3D modeling application rather than in Unity. This rule should also be applied on every subobject in the model, not just the main one. Dynamic batching will also more likely work correctly. These settings should assure that you can use just basic scale 1,1,1 in your scenes to get consistent behavior and no physics problems. To make everything right, set the scale factor in models import settings (leave 0.01 for 3dsMax and Modo, set 1.0 for Maya), and note that sometimes you will need to re-import objects after changing the scale setting.

Sometimes it’s not possible to have this correctly set from your 3D modeling software because of different units these applications are using. It’s important to set the scale correctly. There are several things that the good model should fulfill. It’s critical to have all your models well prepared to be able to use them in your scenes without further modifications.
Common Unity Mistake #2: Working with Unoptimized Models It’s always important to ask yourself the question “can it be reasonably achieved?” If not, you shouldn’t waste your precious resources on something hardly achievable (in case it’s not part of your business strategy to have it as your main competitive advantage, of course).
Performance concerns have to always be in your mind when designing new levels. The way the levels will be designed is crucial for future work because the division of the level influences the performance a lot.
UNITY 3D SOFTWARE HOW TO
It should also be specified how to unify all the measurements to have a consistent scale, and import process throughout the whole application. You should have a clear idea about desired frame rate and vertex budget, so the 3D artist can know in what maximal resolution the models have to be, and how many LOD variations he has to do. Every topic in this article is influenced by this fact.įrom a more technical point of view, it should be necessary to set in advance the whole workflow of creating assets and models while providing them to the programmer, with particular attention to iteration process when the models will need some more changes and refinements. It’s also necessary to set the minimal supported devices specifications (will you support older low-end devices or just more recent models?) to have the idea of what performance and visuals you can afford. You have to be sure what platforms you will be releasing product for, and what platforms are in your plan.
These days, when product marketing is an important part of the whole process, it’s also important to have a clear idea of what the business model of the implemented application will be. Tweet Common Unity Mistake #1: Underestimating Project Planning Phaseįor every project, it’s crucial to determine several things before the application design and programming part of the project even begins.
