No worries on the triangle count. If needed those of us with slower PC's can just fly it on a photofield. But thanks for trying to keep it down.
I think the DC-4 will need more triangles than the Clipper because the landing gear and wheels will take more triangles than the floats did. So I went back to see if I could get rid of any more polygons on the back of the engines where you can't see them in the cowl. I ended up recovering another 3,408 triangles that you can't see so that will help create the gear. To get the tires and wheels to look nice and round takes a lot of triangles to add more segments, and there's four of them on the main gear. I want to keep the total triangle count around the same as the Clipper which I'm not sure I'll be able to do with four 9 cylinder radials. I could end up needed to make them 7 cylinder radials.
You could do the engines as propellers thing I told you about years ago.
I looked at the directions but being honest they were confusing to me so I never tried it. But at the same time that doesn't change the rendering load so the frame rate hit should be the same either way. I do have 135,000 triangles so I think that's enough I just didn't want to use that many so the frame rate hit would be lower.
I whipped up a moki that can be plopped on any model.
I added the nose gear today. Like always it's not scale but it has some scale elements.
Close is good enough for this. I'm sure plenty of tweaks remain for you to ponder in the coming weeks
