Hi guys. I know this question has been asked before but I haven’t seen much activity on it recently. The issue is basically dark shading artifacts on foliage when using ray tracing. This is on a megascans asset but i know this happens on others. So far I’ve tried:

Turning off wind (world position offset) - This stops the weird black effect but I need the wind so this is not an option.  
Turning on ‘Evaluate World position’ - This is only available as a static mesh, not as foliage in a volume or landscape grass material.  
Turn off cast shadows - Stops the effect but then I have no shadows which is less than ideal.

I’m pretty sure this can be omitted with commands as seen here :[link text][1] however I dont think these commands work in the shipped version of 4.26

Thanks for reading!

I’m assuming those console commands will work in a packaged game, you can call them from the console node. Have you tried it?
