Replaced previous image with a new one.

That's a great image.......now add motion blur and some movement on the helix

[Becco_UK]

iker: Thank you. Not at the stage for adding motion blur just yet though. I'm still texturing the model.

Some time ago I tried a propeller at high speed with motion blur and it failed badly. Someone suggested that Maxwells' motion blur doesn't sample sub steps for fast moving objects that are rotating. In my test I ended up with a blurred triangle! I will try with this models prop' blade at a lower rpm!

Another day and some more parts added/ modified to the P-47M model.

In this preview I have made some new wheels that offer greater accuracy. Although not really visible in this render I've also added wing flap hinges - I was hoping to get them working like the real thing but opted for a simpler job.

The bombs have been modified because I thought the original ones would be more at home in a Lancaster bomber than attached to a smaller aircraft!

Have been trying various weathering effects using Painter that I hope to start this stage properly this evening.

The end is in sight!

This is an earlier preview render of the pilot I made for this aircraft. He's a poseable full figure job. Not very detailed but serves the purpose to add a figure into the cockpit.

Getting better and better! I love your latest renders!!

The aircraft is starting to look real nice now Becco, but perhaps you should roughen up the surfaces a bit with dirt, scratched decals and such things..

Most of all i like the way you document this whole process, best i've seen so far on the forum.

NicoR44: Thank you.

Maximus3D: Thank you too. I agree about the need for some dirt. All being well the dirtying up stage of this model starts this evening - I needed to get the panel lines done first so I can use them as a guide where to weather the model. Spent some time yesterday with Painter trying various effects and I think I've found some that hopefully may suit. What I wish to avoid is something too dirty with panels looking like pre-shaded model kit panels.

Found some time yesterday to have another mess with the P-47M model. I decided to dirty the undercarriage bays.

When tracking down what the rgb values are for zinc primate I found that there isn't a standard set. Usually it was varying shades of yellow green so I opted for a rgb value of 136,152, 30.

All the parts to be included within this texture map were given the same Cinema material.

BodyPaint Wizard
For these components I used BodyPaints' wizard. I'm not doing detailed paint work in these areas so I thought it wouldn't matter too much about having disconnected UV's. The wizard was set up to use the material I had already allocated to the chosen parts. I generated a 1986*2048 zinc primate coloured texture map and the only thing I checked for any overlapping UV's.

Using Ambient Occlusion (AO)



It's commonly known that AO can be used to simulate dirt in the 'nooks and cranies' but all it usually does is simply burn the existing colour. I use AO in a slightly different way. In Cinema4D I selected the previously UV'd zinc primate parts and connected them into a single object leaving the original ones in place. I connected the parts so that Cinema would bake an AO map that included all the parts otherwise it only works on sected parts. Then it's just a case of stting up Cinemas bake function and going away for about 30 minutes while it does the calculations. The settings I used are shown in the screen grab. The important bit here is to retain the UV's so that the outputted AO map can be used later, on the individual unconnected parts.

Cinema created a copy of the zinc primate connected parts and hides the original ones and at the same time allocates a new material using the colour and AO maps. All these new things were deleted within Cinema as was the connected parts I had used for the AO creation. All I was interested in was the AO map!

Using The AO Map



Using Paint Shop Pro I used the A0 map as a mask. I mask through a simple motled earth coloured layer onto a zinc primate colour layer. The screen grab shows the result. If necessary, it can be adjusted at a later point in time. This new colour map was saved and used for the Cinema material and to also make a Maxwell material.

How The AO Turned Out



The AO could probably do with some further adjustment but the method provides an easy to use method of getting natural coloured dirt and grime onto parts.
