I have had a strange issue coming up during the last week when using the layered lawn presets. Usually the grass renders looking pretty close to the thumbnail in the library.
However for the last week whenever I use any of the layered lawn presets (it doesn't seem to matter which one) the grass is rendering very dark and clumpy looking. I have attached some images showing the difference.
I have opened a previous file and that renders fine, and have compared the settings side by side and there does not appear to be any difference.
I haven't changed any settings other than to change the border to edge and both are using the exact same lighting and render settings. Can anyone tell me what may be going wrong?
even when reducing the file down to just a small patch of 5x5m grass the file size is too big to upload here unfotunately.
