I just got started on this aircraft model for a new group project.
Just a bounding box, backdrops, and rough fuselage so far...

texturing is way off, as you can see from the reference image, there are NO orangy wireframe lines present. I would re-evaluate your work to make it more realistic. Also try lowering the shading rate component.

Seriously though, I'd love to see how this goes. I have a thing for planes, but I won't admit it.

Edit: BTW Jeff, I tried e-mailing you a while back about San Diego housing but your e-mail bounced back. I'm looking for Accomedations in SD for Siggraph, not the couch, and was wondering if you knew any local info on affordable ones. It doesnt have to be right at the siggrah area. Thanks. yazan at null dot jo

Hahaha. Modo humor. Who knew there was such a thing?
;-P

Lovely project Jeff, please keep posting. Great photo, I love the wrinkly, dented look that old planes like this get. One could probably get that pretty easily with a bump map?

I worked for an architect in Cape Town who flew catalinas in the war, probably for RAF coastal command.

Makes me think I should get back to finishing my spruce goose sometime...

Yazan - Ha Ha ;-)
I sent an email to sdmodo members asking for hotel advice. I will pass along anything I get as I am not too knowledgeable about local hotels.
We have an sdmodo meeting this coming Monday evening, so I will ask there too.
My personal email address is: jeffrutan at mac dot com.

LRoy - Thanks for the encouragement - really helps to keep at it when lots of other things to do!

Grant: Yes - I remember - please finish your spruce goose! I was following that with interest a long time ago. The red civilian conversion model shown above is only one of many reference photos I am using for shape, not final finish. My final model will be a US military version with white belly and dark blue top.

Here is a small update with some fuselage refinement and a tail...

Jeff,
not the best of refs but this may help:

No extra canopies on yours though.

Phunkidude: Thanks! I got some great blueprints (see the backdrops in my first post in this thread) and plenty of great reference photos using Google Images. Mine will have the extra canopies - I will add those later - I am trying to get the basic fuselage shape just right before moving on to any details.

Pierre: Thanks! I didn't have that great image yet! It really shows some fine details in the front.

I'm looking forward to seeing how you do this as well. I know your other models have been impeccable, so I can't wait to see the play by play.

Yeah your blueprints do look much nicer than the ones I found.

Ah, I'm glad you're still working on this Jeff, I was just about to come and poke you with a pencil.

Looking great, but I don't think the underside is quite right. Your keel line appears to be pulled down slightly into a small point (in the front/rear view), along most of its length I think the lower part of the 'V' should be harder/straighter. At the widest point of the hull it's only the top which curves out towards the sides. At the front the underside should be quite concave.

oh the irony. I bought a plastic model of that a couple of years ago and it has been collecting dust on my shelf. I've been wanting to model it, and restarted it in 3 different 3D packages.

I can't wait to see what you come up with.

Grant, Thanks! You are right on both accounts. The reference shots I picked to stare at while shaping the hull were from lower underneath and it appeared to me to have the features I modeled, but looking closer at some other references and especially the 2 you referenced here it is obvious I missed those facts. I am also noticing that there are some very significant differences between different versions of this same plane in construction details - not just the gun turrets, but shape of the tail, nose and even significant surface details. Obviously I need to go take some detailed reference photos of my own of the real one I am trying to model.

Unfortunately I am not finding much time to work on this, but I am committed to finishing it in the next couple of months. More tweaking to do before moving on, but here is an update...

Oh, that's such a bummer when you get halfway through a model and realise you've based it on 2 different (conflicting) references. Been there ;-)

It's looking really good Jeff, and nice wires too.

How dare they change the design of an airplane in wartime!

Looking good Jeff. I'm subscribed to this thread but don't get notices...just have to keep looking this up.

I'm going to try to get my start up soon.

I am having difficulty trying to figure out how to model the window panes in the side blisters. Cuts to sharpen the corners of the frames tend to pull up, pinch and distort what should be a smooth rounded teardrop shape. I may just do the frames as a separate piece from the glass, but I would like to learn how to do this as one piece if I can. I really want to keep the geometry simple, low poly, no edge weighting and preferably all quads (although I have already strayed from all quads in these examples trying to smooth things out).

Any advice?

Thanks,
-Jeff

Hi Jeff,

This is such a nice plane to model. Hoop to see much more of it. Your going strong. Keep up the good work........

IMHO if you want low poly and sharp crisp edges you have a lot of work ahead of you in a unified SDS mesh. That will by its nature be a fight/struggle to the death. Maybe rethink your goal, if it must be modeled detail do them separately - far more efficient and clean. Or to stay pure low poly in SDS and treat them as UVed textures on the simple base geom. My 2cents.

Is looking beautiful Jeff!

-Rob

Forget the low poly man. What do you have all the RAM for anyway? :) Slice it. Dice it. Under 1 million is low poly baby. You oughta see the Wristwatch tutorial. No worries about one mesh there and that's just a tiny watch. Looking good.
