Thank you for your feedback.
I can definitely round off the objects, I was being too conservative with the poly count. I was actually afraid that 19k polys would be too many which was why I was hesitant to round off those rubber bands, rails, and other objects. I'm glad to know that I shouldn't hesitate to shoot for the higher poly counts (80k or more) as you suggested.
I used a point and shoot camera for the playfield texture (Panasonic DMC-ZS3). The playfield resolution came out to 2232x3968. I just tested the reduce noise filter with your recomended settings and it helped quite a bit. I will still need to retake the picture, because the text, lines, and other fine details on the playfield should be clearer than it is currently appearing. I will dig deeper in the camera's exposure settings to try to reduce the noise and capture the playfield's details better.
About your playfield texture resolution, do you take one picture of the entire playfield and split it into two textures? Or do you take two seperate pictures (top and bottom)?
I can add the holes with the sides, and remove the parts in photoshop that couldn't be physically removed from the table. I'll look into the bake shading.
The texel density video was very helpful, thanks for sharing.
Again, thank you for your input, I really appreciate it.
