raytracing with texture

How can i use raytracing with a normal texture that uses alpha. Without raytracing it seems to be OK (except it hasn’t raytracing :slight_smile: )

With this option enabled it goes wrong:

I hope you know what i mean and how i can fix this.

have you done a render? because i think it should work in the render
