I hope I have placed this in the correct sub forum
I have followed this tutorial for a rug using hair particles, but the base of the carpet renders tranparent even it has a solid material applied to to it.
I’ve run through the tutorial again, but can’t see where the error may of come from.
As work around I added a solid object underneath the carpet object to act as the carpet base, but I’m guessing there’s a better solution.
I’ve attached render images of both with and with out the solid object, to show the transparency issue.
Below everything is mesh object I use as a background ( thanks to the great @artfromrachel) and made sure this object wasn’t intersecting.
I’ve stripped down my scene file and uploaded it too.
Stumped, any help would be great.
