Hi,
I'm sorry to hear, you are facing trouble with it. Well, the number of items during the rendering is just estimated and it might be significantly higher – depending on the used distribution map and used features. I would suggest you set the limit to a higher value or even “disable it” by setting it to 0. Let me mention, that's possible to set these limits from the Maxscript in the following way:
$.maxdensity = 0
$.vmaxitems = 0
$.rmaxitems = 0
$.maxfaces = 0
I hope that helps.
Best regards,
