Simulations should be done using the following method:
1. Load the clothing item.
2. At frame 1 apply any style adjustments.
3. Move your timeline slider to frame 15 and apply any body shapes.
4. Move your timeline slider to frame 20 - 25 and apply your pose. Simulate using at least 30 frames. More frames will allow your dress more time to settle.
5. Animated simulation should be used with larger or more busty characters for best results. For thin characters current frame is a good option. There is a simulation preset for smaller characters also.
Please note that when using material presets from addons by other vendors they may alter the simulation settings. For this reason it is recommended that you apply the default simulation settings preset after applying any materials from addon packages.
