I bought some of Forst's tree packs, which look nice, but all I get is pink trees. He said to refresh them in Tree Creator, but that makes no difference. I then tried from scratch, downloading the Tree Creator tutorial pack - same again: pink materials. Are these shaders and materials not ready for HDRP yet? Using the HDRP 6.9.1 version. Or hopefully, have I missed something? Also the trees I bought - some open in Tree Creator, others don't. If I am making a tree in Tree Creator, how do I re-open that tree later, if I want to adjust it. Can't find that either. Bad day - hours on this Thanks.
