FMP: Trying to fix the side


I tried to fix these issues, but failed. I've also remade this panel, and again failed to remove these imperfections, I am now remodeling this panel again, but this time I'm taking extreme care to never move individual vertices. 



I've been trying to use the Boolean tool as much as I can in order to cut accurate forms in the mesh. But I've been finding that the tool isn't very accurate. When using the Boolean function I will normally duplicate the mesh I'm using to cut out the hole, all the meshes involved have their pivot points set to 0.0 on all axises so I can accurately place the meshes exactly where I want them in the scene. I've found that after Booleaning if I then move the duplicated mesh that I used to cut out the hole back to 0.0 that the hole doesn't actually follow the exact form of the mesh. Thus the tool can not be relied upon to create accurate forms. 



Well, the remodel didn't go to plan.



I've started again with this area, Here I have simply made a clean smooth surface. Sadly though I have issues here as well.



Ok finally I'm starting to get some progress here. The area around the vents is mostly smooth, the vents themselves though still need work.  


I've got this down to there only being one crease at the start of the vent. I'm going to try and add more geometry to the shape of these vents now as well. 

I tried  to get rid of the crease at the start of the vents by adding a chamfer, this sadly did not work. 
Also the connections that ran over the top of the car are also visible. 



I'm going to have to stop this process and pick the best of the shells that I have created, simply because I must move on from this area. 


I'm going to go with this front quarter, with single harsh crease at the start of the vent. At least it's neat, also the panels appear mostly flat when viewed with this surface material quality.

Week 5: Day 2 - Problems




After looking at the above model I thought that I had done a good job of removing pinching and general shading errors.  

Because of this I moved on to the interior and then unwrapped and packed the whole car. 

It was at this point that I was made aware of the real challenge when creating a glossy car model body.  This is how reflections and light will completely break at the slightest imperfection causing extremely distorted reflections.




In this image the panel below the side crease that runs the length of the car appears to be flat and smooth. I now know that simply getting the car looking clean at this point has very little bearing to how light will react to the car when it’s in an environment with a glossy finish.


The above image clearly shows that the car shell is far from finished. I’m not actually shore how to fix these issues, the errors are extreme and seam inconsistent with the slight errors that must exist in the geometry. I don’t know if this can be fixed by simply moving individual vertexes until the area is smoother, the tolerances here might be so fine that this will be impossible to do by hand. This could also be a problem with the normals. 

Tyres

Prior to these revelations I did make several high poly tyres and backed these down. 


First high poly tire



Second bake. I now need to come up with a better design for the centre of the tire as this one isn't backing down very well.

FMP: Still Modeling

Vents Below Windscreen




I was shown a quick way of removing tries from a wheel. This is to Select an inner edge and then to go to modeling drop down and then Dot Loop, this will select every over edge along that line of edges. Then you can remove these edges by clicking collapse. 







This didn't actually work very well, shadows are being pinched up every edge making up the centre of the tyre. 

I finally did the front window , i've been putting it off. 


I actually did this about a week ago. I've since retopologized, done the interior, and unwrapped the majority of the car. 





These images are showing the interior "Tub", All these parts in the image are also unwrapped, and have had the Average normals scripped ran on them.

FMP: I need to move on from the shell

I've spent today trying to get rid of any shadow/light pinching. I can still see the occasional issue with this, but I need to move on.

According to my planning I should have started Texturing today. Although I have timetabled in a week of unaccounted time during this project. This set back is eating into this time.

Currently I am now going to move onto creating a basic interior. With my knowledge of Sub D work flow I should be able to model this allot faster than I've just done the body.

FMP: Retopology

A whole day of retopology and now i'm apparently 20k under budget , which is good.
