I put together this rough guide so that we can try to gauge which pieces are taxing our forge maps the most. I tested some common pieces by placing the maximum amount of them and timing the lighting generation process. Feel free to reply with other interesting results. See the results below: Testing was all done on the Awash skybox. 200 Wall Coliseums = 28 SECONDS 200 Cylinder large = 21 SECONDS 200 Walkway large = 16 SECONDS 200 Brace large = 11 seconds 100 Flat large terrain = 10 seconds 100 Cliff large terrain = 8 seconds 200 Ramp circular large = 7 seconds 100 Room triple = 6 seconds 200 Dish = 6 seconds 200 Window Coliseums = 6 seconds 200 Platform Xlarge = 6 seconds 200 10x10 Blocks = 4 seconds 200 Ramp stunt = 3 seconds 200 Seastack rocks = 3 seconds 200 Bridge Xlarge = Little to no delay 200 Landing pad = Little to no delay 200 Platform Large = Little to no delay 200 Tunnel long = Little to no delay 200 Cover glass = Little to no delay 100 Container open large = No delay 100 Grass planes = No delay 200 Glass panel 3x3 = No delay 64 Heavy man cannon = No delay 64 Tin cups = No delay 32 Light red = No delay 200 Tree 01 large = No delay, but obvious effect on performance meter
Good stuff. This is definitely a good starting point in determining which objects have the most impact on framerate and lighting.
Do not forge on Bloodline. I ran into really stupid lighting issues. No matter what I do there are just random pieces that are crazy bright.
