JAS-39 Gripen

Hello Manos,
From what I see, issue is that you are working too much on an automatic way.
When you unwrap an object of your aircraft you have to figure out :
- If this object is gonna be specifically textured (type 1)
- If object will simply receive an ambient occlusion treatment (type 2)
Type 1 means that you need a clean uvw, which can be understood by human.
Type 2 means that a simple flatten with minimum spacing will do. You will apply a base texture color, and texture backing will do the rest.If you are proceeding type 1, like fuselage, you will often have to unwrap polygon by polygon. It means that you will have to select by hand polygons that have the same horizontal / vertical aspect to unwrap them with a back/front - right/left normal mapping.
Unwrapping is a long process. If you do not prepare it properly, it will be a true nightmare to create texture for.
Be ready to spend much time on it.
Also, even I would time to do it, I would not do it. Why?
- Unwrapping is extremely personnal. If I unwrap, you might not understand what I did.
- If I do it, you would not learn how to make it. I learned unwrapping starting by simple objects, like an house. Then, I moved to missiles and bombs. Then, one day, I did an aircraft. I am still so far to know everything about unwrapping.
- Unwrapping is somehow one of the most boring and hair tearing phase. Also, working on one model I haven’t created is not ok to me.
So, I think it’s time for you to suffer, to learn, experiment and succeed with your unwrapping. You are on that phase we all met!

As it seems you have right my friend… I did something simmilar to the first attempt of the F-5 also in the second cause i wanted very easy and not that complicated uvmapping as u suggested back then. But i had A LOT of free time to do it. I had almost 2-3 days off from real work and nothing really to do (no money to get out ) so i had more than 1 whole night and i was selecting as u said face by face the parts i wanted to be textured. The general idea worked but its not and still isnt flat so in complex camo also the panel lines and rivets in some points get distorted. So here i wanna do it flat is it gonna work with the way u said (selecting faces etc?) I wanted to make it like a box or something you know sides L/R and Upper and lower but anyway i will find the way as face by face it is time consuming and iritating sometimes but it worth it. Thanks for the advices…
Cheers

In addition to Radiums good post, …
First of all make really sure your geometry is good,
no overlooked and needless single tris, etc.Next, the automatic unwrapping tools don’t do always a satisfying job
on complex geometry.
It’s the 3D modellers job to fix those parts.That’s why I unwrap my objects “manually” often.
Stack example:
Unwrap UVW
UVW Mapping
Poly SelectWith the Poly Select modifier and Poly subobject activated select
all polys you want to map.With the UVW Mapping modifier choose projection of mapping (cylindrical, planar, …)
Hint: a click on the UVW Mapping modifier in the stack results in a yellow
colored mapping “Gizmo”, which can be tranformed and rotated.With the Unwrap UVW modifier place, scale, mirror, etc. your mapping.
Hint: you can still try one of the auto mapping toys with the actually selected
polys.Repeat above stack example for other parts of your model.
Another methode to solve your problem is to use “detach, weld and stitch”
within your Unwrap UVW modifier.Cheers,

So i had some time to start unwrapping as i have it in my mind at least to be. I started with automatic and then slowly selecting each automated piece of map i want to be in one area (upper and lower in this) and weld them together,this far is going well it will take some time but i think i will have this weekend enough to continue. I used also this letter/number test texture i found and it seems good the whole idea this far. We will see
-
Just doing some tests to see the current mapping. Nothing final….
-
…I like the “TEST”! Almost a keeper.

Just wanted to have a text so i can see how flat is the whole thing there hahahaha good one Stevie! When i will finish ill make one texture for u writing “TEST” maybe something like this:
Anyway i think im in a good way to map it… still long way to go and i have a long night in front of me
And a more “artistic” test :

https://image.ibb.co/cX3Y9w/Gripen17.jpgI see you’ve started also to draw panel lines to prove your mapping.
IMHO, Go ahead and draw more panel lines.
If you find a problematc area, correct mapping.YOU have full control of mapping AND pixels !

LSWell im not done mapping yet my friend those panel lines are there just to see the distortion if there is any and how i can fix it. I will draw panel lines of course as soon ill finish the mapping 100% theres still areas i wanna cover and Areas that must be cleaned or deleted as it seems the geometry of the model needs a lot of cleaning. I have some tools to make it happen i hope i won’t “break” anything . Also align the maps so the Texturing and “paneling” will be easier to do ofcourse

…love it!

Ok i will be back in track in the coming days. I had a very rough Christmas period in work (still is a bit too much) had also a short vacation after it and now im willing to start really working all those projects and finish them slowly. More updates soon.
PS. This covers all the models i have started porting/making or whatever -
-
Test shots (not textured yet) in game to see any weird tris and stuff in game… looks good this far! Some areas need to be fixed a bit and also some areas need to be “closed” as if you look from a angle behind the cockpit and inside towrds the instrument panel you can see through the nose that means either the nose section will be doublesided or i will extend the cockpit wall (much better and not expensive in tris) Currently standing at 23457 tris

Pretty! Comes into shape slowly…

Pretty! Comes into shape slowly…
Yeah… slowly… i found more issues looking closely. After the welding i found that many things has to be fixed…

Soon will be some news on this model stay tuned
-
I am waiting for. Thank to keep it alive and I hope it will be succeed. I’m working a new more detailed and accurate model now
-
seems great, I reaaly hope you will succeed
