Update Low Poly SU cars

Hi Richard,
Just a quick update to say I was wrong about VRay not supporting weight mapping- it's done via a blend map and two diffuse layers/materials, probably in just the same way as Maxwell.
Dying to see the fruits of your labours- that Audi pic is still a real teaser.
Hey thanks for the reply Jackson!
I'm not sure blending (vray) and weight mapping (maxwell/fry) might be the same thing?
In maxwell weight maps either blend materials by the grey weight (50% grey = 50% blend) or can exclude / include just like clipping.
For example with the car (audi) posted the the glass layer of the material will have a weight map that is white (255) for the glass areas and black (0) for all others. The other areas will be white with black for the window areas, though a specularity map will gloss or matt the paint / trim / tyres. However what I was working on was the grey areas of the weight maps where some layers may or may not blend.
I'm trying to get the whole car as one material so it is just dropped in scene and rendered without too much user fuss! If every part of the car assigned a separate material as commonly done now and opened in say maxwell studio the material list will saturate with so many meaningless materials: car glass, trim, alloys, tyres, car paint red, car paint yellow, number plate etc etc. It just becomes confusing in a large scene and one has to dig to find any important materials to be adjusted.
I'm thinking that if the car can be done in one material then the material list can be Audi silver, mazda red, nissan gold etc. Simple!
I've been working on even setting up the low poly interiors I use for exterior renders this way so that the materials for the exterior (the ones I want to edit) are easily found and the rest shows as Interior 1, interior 2 etc - at present even a low poly interior for this use may have 10-20 materials, more than the rest of the scene!

Yep, AFAIK "weight" mapping and "blend" mapping are just different terms for the same method so your impressive hard work should translate over to VRay (or any render prog) without any problems. In VRay you have two diffuse bitmaps which are overlaid so the first always has precedence/render priority over the second. A grayscale blend map is applied to the first diffuse map which, by making that diffuse layer more or less transparent, allows the second diffuse layer to show through instead or creates a blend of the two where the blend map is grey. I've used this method mostly for road surfaces where I want a high detail tiling texture like tarmac, but I need it to show wear and tear and dirt where water has run off. The actual bitmaps which render might only be 2000 x 2000 px, but the blend map may be up to 10000 x 10000 px to allow for control over the whole rendered surface.
I seriously admire your determination and single-mindedness in streamlining the whole modelling/rendering process. I spent a considerable amount of time stripping all my SU car components of their many various materials and replacing them with a distinct set- Car Chrome, Car Tyres, Car Black Plastic, Car Aluminium Rims, etc (all with corresponding saved VRay equivalents) so at least when I drop a bunch of cars into a scene I only have maybe 10 materials to import and all the cars are taken care of. I had a recent forum conversation with a VRay user who was complaining that he was having trouble keeping track of the materials in his skp/VRay file- it turned out he was dropping 3DW car components straight into his model. He had over 450 materials undoubtedly with random, completely meaningless names. I never once regretted spending a bit of my spare time to organise my components and material libraries- the time (and stress) savings are easily worth it. Having one material per car would be awesome
Keep us updated with your progress, if only to generate more marketing for your product!

p.s. still dying to know how you apply the UV mapping to such organic forms in SU; lots of construction geometry and eye dropper/projected texturing?

Rather late than never
, I got around to playing with your model, I used Artisan to divide and smooth it further, added a bunch of detail, created a soft top roof and rendered in Thea.Heavy mesh (no longer low poly)
Quick Thea render, Raw render. no photoshop
I love Sunbeam Alpine's (mark 1)

That's pure sex pete! There is something so sweet about older numbers, nothing new compares really!

Oh yeah, the Sunbeam was a pathetically under powered 2 Lt 4 speed British sports car but what it lacked in Horsepower and torque it made up with sex appeal. It was made for swanking on par with the MG's, slow country drives, and many weekends of repairing oil leaks. Made for a true car enthusiast, I have always wanted one, nearly bought one in the mid 90's but got an Esprit twin turbo instead from the same estate auction. ( would have bought both if I could have)

Beautiful car! The model's not too shabby either, Pete.

Stop it!!!!!!

White paint with reflections, without loosing the details, how beautiful is this....
Thea is amazing, into the right hands! Congrats Master!

How you did the composition, if is raw render?
The shadows on ground are very accurate.
Are you so kind to write some steps?
Thank you. -

Hi Pete,
superb model and render. My dream was always the Morgan Plus 4 I could find until now no 3D model.

I love Top gear UK, so decided to watch the USA version on Netflix recently (not even close to the UK version) they featured the new Morgan:

What fascinates me is also the production of the Morgan roadster.
