Cave Vines Render Incorrectly With Ray Tracing On

Cave vines have their texture layered on top of itself with Ray Tracing on. This causes the texture to look much thicker and more confusing, and causes some z-fighting issues.

Steps to Reproduce:

1. Open any world with Ray Tracing off

2. Place Cave Vines anywhere in the world

3. Toggle Ray Tracing on and off

Observed Results:

The texture appears to change when Ray Tracing is toggled on, and seems to be layered on top of itself, which causes z-fighting.

Expected Results:

The texture should remain the same as with Ray Tracing off, and there should be no z-fighting.
