Hello everyone!

As a short introduction, I am trying to model a tractor for a game that I am working on and I am stuck now because of my model’s topology.

Workflow:

I am trying to make this a game-ready model, so I began modelling the high poly mesh first and do some hard surface modeling to better define the details of my model, and after that I am supposed to make the low poly version based on the final high poly model. (If I am understanding the workflow correctly)

So I have used subsurf to give the model the shape of my object and after that I tried using booleans for carving out the windshield, the doors and the back windows of the tractor.

And there is my problem, by using this workflow it became very hard for me to grasp how should I make the door curvature above the fender.

I tried different methods, by duplicating the faces of the cabin and then reshaping them to make thata curvature (which is messing up badly my cabin topology) and I have tried cutting the entire shape of the door, and after that I have tried to cover it up somehow.

At first I thought that I will just make a cover by using my fender’s shape and extrude down some geometry and make a cover out of that, but the fender’s edge goes all the way and bends to the back so I cannot use the entire fender edge. And by using a fraction of the fender’s edge becomes really hard to try and match the fender’s shape with the cabin’s shape in a way that will not look horrific in the end. (I want to abandon this method because I don’t think it can give me the desired result in the end)

So I am now thinking of somehow modify my topology in the correct way to allow my cabin to take the correct form of boolean nicely but I am stuck finding a good strategy to tackle the problem in a clean way and in the correct way.

I have some experience in CAD software from my Uni courses and there it seems to be easier achieving these kind of shapes and I tackled Blender for many years by now, but never quite reached a solid ground under my feet for some reason.

I have also watched a ton of youtube videos in the past days being stuck here, but I didn’t quite found anything that could answer to my question so I could solve my problem.

Thanks for hearing my frustration and also my little rant from fighting with Blender. I hope that someone could help me getting on the right track in this matter!
