AmbiguousPackage: Thanks for the link. I used it to download references. |They have nice collection and pictures are focused on details and are highres. Great help and i had to redo some parts which at first time just guessed by hand made scalled models. hehe
Xoliul: All you said makes sense. I went as you suggested across main parts and adjusted smoothing of corners to make them look less sharp. And for the rest of the modelling process i kept in mind what you said. Thank you.
Anyway here is another update on this. On high modelling pass i am at the end with all parts modelled. It was pretty good with polygon count after i started to model wheels and straps. Then it jumped from 1 to 2.7 and 4 milions with just turbosmooth interactions on 2 value.
Tomorrow i will start slowly with lowpoly modelling. May i ask what kind of mesh is better to represent straps. Single standalone pieces or just one mesh divided? I would say even if i will go with standalone meshes i can stay under 10k for whole tank.
