Hi,
When facing this kind of issue, you can check more details under the
General >
Forest Stats window. It should give you a hint of where the problem is. In the case of big areas or high density, you may reach the
Max items /
Max faces for viewport / render limits, and you may need to increase some of them. Since the Forest Pack Pro/Lite 5.0.5, "All scattering limits (
Distribution >
Max. Density,
Display >
Max Items/Faces) can be disabled by
setting the value to zero." It's also possible to set them from Maxscript in the following way:
$.maxdensity = 0
$.vmaxitems = 0
$.rmaxitems = 0
$.maxfaces = 0Please feel free to have a look at
this related post regarding the error message ("Some forests were not built correctly in the last render").
I hope that helps.
Best regards,
