For these bugs, I’m using the latest Neon, and the renderer is set to rhino.
Bump maps: I’m still having some real troubles with bump maps in Neon – I used to get some nice realistic mirrored effects with subtle bump maps and edge softening turned on. The bump maps look ok until I turn on edge softening, then everything goes all zig-zaggy. I’ve reported this in the past… I thought it was fixed at some point, but if it was, it’s back.
Turning bump maps on and off makes everything go all, well, neon colored. When I change a bump map or turn on on or off while neon is running, the object gets all trippy colored and I have to set the viewport to shaded then back to neon. While this is easy to work around, it does slow the process quite a bit, since starting neon over from scratch is much slower than updated a neon viewport.
