making a car with an interior – workflow

Cirmius

Hi,

I coldn't find any tips on the internet about it, although I think its very important in game ready models. As the title says – what's the workflow for the cars with interiors?

I just finished an exterior with a blueprint of Volvo 240 and I don't have any clue how should I start with the interior. Should it be individual, non-extruded mesh? "Solidify" in Blender breaks the topology inside of a car and it works with simple separted meshes like car doors.

I duplicated the roof, scaled it down and now I'm connecting faces manually.

It works for now but I'm pretty sure it's not correct workflow, because it takes a long time and still you can easy screw something up.

solidify issues are typically caused by either normals facing different directions or overall non-uniform scale.

Try recalculating normals or clear/apply scale, respectively.

No hard and fast rules, in terms modeling an interior (low - mid - high) just what effectively works dependant on an envisioned goal, whether pre-rendered visual or realtime

Thanks for the tutorials!

Finally I finished my Volvo and I want to rig it. I see in tutorials that the wheels, car doors are separated meshes for the rig, but I don't really know when you should separate them for the rig or when it should be just by vertex group.

I want the model to make it ready for Unreal Engine.

Since they're hard surfaces, it's best to detach them as separate meshes. Then you can rig and animate without vertex weights, which is easier and has (marginally) better performance.
