Thanks Danny, thats a nice straightforward tute.

I have just been doing a cleanup of my folders and apps (again!), where do all these things come from, am I to take the blame?

Anyway, I came accross several boat building Pdf's in an odd folder--why they were saved there????---that I had forgotten about.
I guess I have hours of frustration ahead of me!

The images are sample from those pdf's

Hi Brian,

>>>I just HAVE to experiment with the Pilou method.

Construction as with pushing/pulling control points can appear an easy route, but it can add its own problems with good smoothing.

I have been looking at a boat construction with using cross_sections, but that again can cause some problems unless the cross_sections are very accurate.

I have now decided to simply construct with curves/sweeps, really just a guess, but I then have no problems with smoothing. A very quick example is a rowing boat I have just made (it only took a few minutes).




I will expand on this to create something bigger.

Another method some rustic :)
Move verticaly A and resize it then make boolean diff ;)

Placed in the memory file.
Thanks

For resize something in the case of the previous boat
Call Scale transform, draw an helper line on the boat's axe from clic to the brow to clic the poop
so you obtain the middle's boat axe = first click of the Scale, then second click of the Scale inside the boat on the the axe's helper or enter a % of reduction ;)

some boats' blue prints ;)

Thanks Pilou.

Hi Brian.

Your Boat looks great, even with the planking. Don`t see a problem here(edit: ok the plank texture is a bit distorted in one direction.
Maybe try to avoid texture-stretching by using different tiling factors for x and y or u and w).
I`m really admiring your uv-work. Something that has always scared me a bit.
I hope Michael could do some Magic here;-)

By the way, i would use a fresnel effect(ior) on all materials.
That is one reason why all the unbiased renders look so real (and the lightning is the other reason of course).

Thanks Dirk.
Using the fresnell effect all the time? The very first time I have, ever, heard that one?
Will investigate.
Brian

Dirk.
In Carrara, I use the Fresnell plugin shader from here---

Some initial comparrison tests suggest that, as I have normally done, Fresnell needs to be used judicially.
Appreciate comments from others.

Hi Brian,

yesterday i`ve made some tests again and i couldn`t detect much difference by using fresnel or not.
I am a bit biased by the unbiased renderengines like Maxwell and Fryrender(nice worldplay :-)) and they have turned fresnel all the time on , cause you can`t turn it off. You just change it`s intesity mainly by the ior and by roughness.
I`ve here one tutorial which is about procedural textures in c4d and there the author uses fresnel. Inside the tutorial he has two images, one with fresnel turned on and one without it, so you can compare its effect.
Unfortunenatly the tutorial is in spanish. I can`t speak or read spanish either but the images are named in english so you can easily see of what i spoke here. The link to the english text seems to be broken, so here is the spanish one:

The fresnel effect in a way accents three- dimensionality when there are reflections visible on an object.

The few quick tests I did shows a softening/degredation of contrasts/shadows on some objects.
That, especially, on objects which should not be reflective.
In Carrara, we have the Reflection channel as basic. The Fresnel plugins being a more "specialised refinement" in that area.
(Carrara is pretty good with it's shading tree variables)

Unbiased engines also have blurry reflections/refractions on ALL objects. This is how you find materials in reality. For materials such as glass/chrome, the sampling must be cranked up very high. For biased engines it will make your render time painfully long, but is more accurate...
