Ah-ha - the next challange

Thanks for the info, Privateer. I'll just spend a little bit more time on the reflections and then look at the water streams.
For reflections I have been adjusting the "waterReflection@......" parameter which I have created in the sim file (having deleted it in the dat file). I have made the parameters the same as those for the VII's. Doing that has got rid of the great 'V' or 'U' shape darkness behind the sub (I see you initially had the same on the 14), but I don't get the reflection of the boat in the water - more than likely another parameter

I also do not get water transparency around the boat.
As I said - long ways to go for me. Just thought I would throw it out to the community to see if anybody else was doing the same model - avoid duplication. Seems there are few people looking at new ships, boats and planes.
