T3D 1.1 Beta 3 - Huge Performance Drop with Shadowless Groundcover and Point Light Shadows - RESOLVED

Thread Body:

Build: 1.1 Beta 3

Platform: Windows XP 32bit

Target: Editors

Issues: When a pointlight is set to cast shadows and interacts with the groundcover, there is a huge performance drop, even if all the groundcover shapes materials are set to not cast any shadows.

Steps to Repeat:
1. Create a terrain and a ground cover with 1 billboard and 3 meshes and a dense amount of it.
2. Create some point light shadows interacting with the groundcover and set them to cast shadows.






As you can see, FPS dropped from 125 to 57 even if no shadows are cast.
