Question by srivello · Aug 26, 2015 at 01:02 PM · animationscalelegacylegacyanimation

Legacy Animation Scale Unpredictable if FBX Import Setting Read/Write Enabled = false

UnityIssueTracker_LegacyAnimationScale_Example

Version: 1.0

Questions

  1. Anyone else experiencing this issue?

  2. Will the issue exist with mechanim?

  3. Will the issue exist with Unity 5?

  4. Any other workarounds?

Bug

  • Depending on fbx import settings, the scale of model meshes are dramatically off starting the moment the legacy animation plays. It is obvious.

  • Reproduction 100% (10 of 10 attempts) on device

  • Tested device(s): iPhone 4, iOS 7.1.2. Probably others.

  • Tested Unity Editor(s): Unity4.6.7p3

  • Workaround (see 3a.) is not desirable

Setup Instructions

  1. Set 'Read/Write Enabled" (RWE) to true/false on /Assets/Models/props.fbx

  2. Run in editor... no bug.

  3. Run on device...
    • 3a. If (RWE) is true, no bug.

    • 3b. If (RWE) is false, there is a clear and consistent bug.

Play Instructions

  1. Run the scene

  2. Hold mouse button 0 down to play animation "up"

  3. Release mouse button 0 to play animation "down"

Project

  • Not attached due to legal/copyright restrictions
