Spinning Around

With a bit of time off over Christmas the external mapping is now more or less finished, give or take some minor animated parts that will go on a separate small texture. This has also let me check the different textures are aligned properly by applying the standard pattern camouflage. At the moment the textures are 2048×2048 but I’ll up this to 4096×4096 for the final product.

I’ve also modelled the four bladed prop, this appears to be more or less the same as was used on the later two-stage Merlin Spitfires. It was only used on the low-level Seafires with the cropped supercharger that gave combat power up to 2750′. The standard Merlin gave max boost up to 14000′ and was paired with the three bladed prop. Oddly although the Spitfire V came in normal and low-level versions as well it only seems to have ever had the three bladed prop.

With a single-speed single-stage supercharger as used in the early Merlins the cropped unit for the low-level version took less power from the engine . Hence although it was providing the same boost as the standard engine at 2750′ the engine was providing more power to the propeller, by a few hundred horsepower.
