Yes, yes, I know there have been many posts about this because I've read them all. I've tried to apply the blendgroundtograss007, make it a displacement, alpha paint it...so on and so forth. I did, however, get it to work once, but I was playing around with other textures and haven't been able to get it back. I've also changed the detail.vbsp to detail_trainyard.vbsp as well as the detail material file to detail/detailsprites_trainyard. Other blend textures with yellow grass work fine. Does anyone have a solution?
