All - Thanks for the quick response. An attempt to add more detail on the issue.
I'm using a mixture of stock and freely available segments/entities but most come from the FPS Stock or new Model Packs. A few things I picked up off of FPS Free (just entities, not segments). I have tried characters from the SciFi, WWII, model packs 5 and 6 I believe. Same issue for all characters. The entities are placed on the floor (using Shift+Enter to line them up).
I have changed the settings for light in the global script to reduce ambient light. I have tried changing the settings for shaders and lighting in the Build Game settings (experimenting with each setting). This had no effect.
I'm using Sprites from the Sprite Pack 1 in the level. A difference from the test level that worked.
Characters are slipping completely through the floor. The animations run, but the character quickly drifts through the floor segment and disappears.
FPSC Version is 1.06.
My system is a Pentium 4 Dual Core, 2 GB Ram, nVidia GeForce Go 7600 running Vista (one of my greatest regrets in life). I could easily blame Vista for it given all the other problems its created, but the problem seems specific to this level.
Thanks for your help with this. I hate to toss the work I've done.
