Awesome! That is surreal! I love the scene and the under-color blend through, nicely done.

Can I make one small comment, maybe you could try to yellow the white a-bit, see how it looks. I believe non-yellowing white was not available as of yet. Plus the white would have the tint of color from the top coat varnish too.

Great model & great renderings Becco! I hope you'll eventually do a large format render (1600 x 1200 or 1920 x 1200) for a PC "wallpaper".

I do agree with womenfly2; I'd dirty-up the white cross backgrounds a bit more & make the ribs show through at least as much as they do on the blue undersurfaces.

Thanks & please post more!!!

womenfly2: Thank you. I will dirty the white a little but not too much. Was varnish applied over the white or was the white painted over the varnish?

Patrick: Thank you too. The wing rib definition depends a lot on veiwing angles, lighting direction and probably most important the surface material. I've seen a few 3D models where the wing rib effect look over done with very difuse non reflective materials being used. The 'cloth' on this model was simulated with Cinemas' cloth engine and I feel it turned out fairly close (but not perfect!).

This early (October, 2007) work in progress shows the wing ribs clearer

Something to shoot at! I was toying with the idea of making a tail section of another aircraft to place in a render - the plans shown here are of a S.E.5a. drawn by W Wylam in 1944. The pilot has yet to be given some bones - hence the strange pose in this preview!

Using some reshaped cubes in Hyper Nurbs and the tail section begins to get formed. using a simple plain material for now - to be textured when some detail is added.

Becco,

I had previously posted my Dr.I horizontal tail drawing that correctly shows its unique elevator curves and rib spacing. Here it is again for reference to enhance your fine Triplane rendering.

Just my opinion, un-varnished white would turn to a yellowish tinted white over time. White over varnished would be tinted the color of the varnish.

I love were your going with this!

Regarding the yellowish color (more "tint") caused by the final varnish coating applied over the doped fabric, I have a large section of original "five" color Fokker D.VII lozenge wing fabric with German cross that today shows much yellowing tint caused by the aged final varnish coating. Where this varnish coating has cracked away, and in surface areas where some lozenge fabric rib tapes have pealed back, you can see fresh doped lozenge fabric of brighter color underneath where the yellowish tinted and aged varnish coating had not penetrated.

I assume the Dr.I was also given a final coat of varnish over the doped fabric, which over time would have resulted in a slight yellowish color tint over the upper surface streaked olive dope into the linen fabric, lower surface solid sky blue dope, and white doped German cross border areas. These surfaces were probably all tinged with a slight yellowish color, especially over time in field service use.

gipsymoth236k: Thank you for all that useful info'. I remember checking my Dr.1 tail with your drawing last year and accepted there were differences - my internal 3d framework is shown as red overlayed over your drawing. At the time I did adjust the front of the tail but didn't adjust the rear curves. Your rudder drawing got fully used though and helped to get that part much more accurate.

I assume surface yellowing would not amount to much at the time these aircraft were operational all those years ago. I think what's wrong with my finish is that the overall rekective and roughness properties are uniform. For the next proper render I will be converting the texture 'dirt' layers into reflection and roughness maps for use in the materials, particularly the 'cloth' parts. This (I hope) will also make the surface look dirtier and more natural.

womenfly2: I agree over time white paint would yellow but over how much time would this become noticable? The white 'cross' borders have been slightly yellowed but the present in progress render simulates sunlight so they still look white! Let's see how things change when reflection maps are made and used in the material?

Nothing to do with the Dr.1 model but this didn't seem worth starting a new thread. It's a rough and ready wing section using true volumetric sub suface scattering through the cloth surfaces. I hope to find time in future to develop this into a nice looking doped linen effect. Still trying to work out how to achieve the colour of the scattering though
