Hi. I upgraded my unity project (using 5.5.4p4) to 2017.1.2p4 recently. Then I found that particle systems using Mesh renderer doesn’t work correctly.
I found the problems like below:
- Vertex position for vertex shader is changed from object-space to world-space. Additionally, unity_ObjectToWorld and unity_WorldToObject seems to be identity matrix.
- TEXCOORD0 of vertex input is incorrect.
- When Scaling Mode of particle system is Hierarchy, the result is different between 5.5 and 2017.1.
Is there any solution or documentation for this issue?
