So, using Unreal to create assets for SC.... so for CIG. So Unreal is being used for SC (at least ToW), at least for modelling because.... its better than CryEngine for this?
Then why are CIG still creating models in CryEngine? Surely CIG should be hiring more Unreal people for the creation of models?
And there is still the suspicion that ToW is being made on Unreal rather than CryEngine.
UE is a standard in gaming industry. CE was but is not anymore since several years.
So when you have a company that works and will work on mutiple modern projects, it's better to use the tools used by the industry (UE, Maya, Speed tree, etc) and have staff able to use those tools. You have also established workflow in a company, often independant of the projects. So if your artistic workflow and all your artist staff use UE, you stick to UE, even if your final project is in UE, Unity or CE. Prototyping can be done in softwares completly differents from the software used for the final product.
For instance, a long time ago I was prototyping the websites for my customers with Dreamweaver (quick and easy). But even if Dreamweaver was able to create websites, I was only prototyping with it because the code given by this software was awful. Now I don't protoype anymore but the guys I work with use Figma even for a final project done with Bootstraps. They could use Bootstrapstudio to prototype (this software can generate the final website directly from prototype), but Figma is better and quicker for what they need.
CIG doesn't work on multiple projects, only 2 that extensively use CE and only CE. So having staff that know UE for now is not necessary or mandatory. It's better for CIG to have experts in CE. Perhaps they have some guys using UE for prototyping but it's just for that : prototyping.
