This is really useful for my work. However, it says that the plug-in works for UE4 4.24 but I just tested 4.24.3 doesn't work. Looks like it only works with 4.24.0. This is a history version of UE4 and I'm not sure where to download it...  ... View more

found the mistake: should change PlantMix(listRange(mix,5,100)) to PlantMix(listRange(mix,5,1000))..I wish there was an option on this forum for me to delete solved comments : )  ... View more

There is no error message showing. But I noticed it only generated a certain amount of plants (stop after a few loops).  ... View more

sorry. For the sake of space I didn't put all plants in _getMix. The plant list is actually really long. If you could replace the _getMix to the following:  _getMix= "Sugar_Maple;12;20.65;5.55;0.2203;Sugar_Maple;10;20.68;5.72;0.2233;Sugar_Maple;24;27.92;5.88;0.2263;Sugar_Maple;33;32.67;6.05;0.2293;Sugar_Maple;52;41.58;6.21;0.2323;Sugar_Maple;6;14.86;4.91;0.2086;Sugar_Maple;5;13.83;4.75;0.2056;Sugar_Maple;5;13.0;4.58;0.2026;Sugar_Maple;5;12.23;4.42;0.1996;White_Ash;8;22.27;6.21;0.2323;Red_Maple;4;14.2;4.91;0.2086;Sugar_Maple;18;23.32;5.55;0.2203;Sugar_Maple;17;23.61;5.72;0.2233;Sugar_Maple;24;27.56;5.88;0.2263;Sugar_Maple;29;30.82;6.05;0.2293;Sugar_Maple;46;38.97;6.21;0.2323;Sugar_Maple;6;14.32;4.75;0.2056;Sugar_Maple;5;12.27;4.42;0.1996;White_Ash;10;23.22;6.21;0.2323;Red_Maple;5;12.12;4.42;0.1996;White_Pine;5;11.49;4.25;0.1966;Black_Cherry;18;23.53;5.55;0.2203;Black_Cherry;6;12.44;4.42;0.1996;Black_Cherry;5;11.5;4.25;0.1966;Bur_Oak;11;19.69;5.39;0.2173;Bur_Oak;5;12.11;4.42;0.1996;Paper_Birch;7;16.91;5.23;0.2143;Paper_Birch;12;20.06;5.39;0.2173;Quaking_Aspen;6;17.96;5.55;0.2203;Red_Maple;7;18.71;5.55;0.2203;Red_Maple;5;12.12;4.42;0.1996;Red_Maple;5;11.49;4.25;0.1966;Red_Pine;12;21.59;5.72;0.2233;White_Pine;18;23.39;5.55;0.2203;White_Pine;22;26.16;5.72;0.2233;White_Pine;22;26.74;5.88;0.2263;Paper_Birch;5;18.5;5.72;0.2233;Quaking_Aspen;2;17.23;5.72;0.2233;Red_Maple;4;17.96;5.72;0.2233;Red_Maple;5;19.39;5.88;0.2263;Red_Maple;12;23.08;6.05;0.2293;Northen_Red_Oak;30;30.25;5.88;0.2263;Northen_Red_Oak;44;37.57;6.05;0.2293;Northen_Red_Oak;37;35.22;6.21;0.2323;White_Pine;5;17.5;5.55;0.2203;White_Pine;6;18.79;5.72;0.2233;Sugar_Maple;6;14.76;4.91;0.2086;Sugar_Maple;5;12.21;4.42;0.1996;Paper_Birch;7;19.15;5.72;0.2233;Quaking_Aspen;3;17.37;5.72;0.2233;Red_Maple;6;18.81;5.72;0.2233;Red_Maple;7;20.26;5.88;0.2263;Red_Maple;11;22.92;6.05;0.2293;Northen_Red_Oak;27;29.17;5.88;0.2263;Northen_Red_Oak;38;34.9;6.05;0.2293;Northen_Red_Oak;30;31.96;6.21;0.2323;White_Pine;11;20.28;5.55;0.2203;White_Pine;13;22.1;5.72;0.2233;Balsam_Fir;4;18.66;5.88;0.2263;Balsam_Fir;3;19.33;6.05;0.2293;Balsam_Fir;3;19.98;6.21;0.2323;Balsam_Fir;3;20.63;6.38;0.2353;Balsam_Fir;3;21.57;6.54;0.2383;Black_Ash;4;18.15;5.72;0.2233;Black_Ash;4;18.84;5.88;0.2263;Paper_Birch;4;20.33;6.21;0.2323;Red_Maple;5;18.23;5.72;0.2233;Red_Maple;5;19.29;5.88;0.2263;Red_Maple;4;20.3;6.21;0.2323;Red_Maple;4;21.31;6.38;0.2353;Sugar_Maple;7;19.52;5.72;0.2233;Sugar_Maple;8;20.51;5.88;0.2263;Sugar_Maple;5;11.5;4.25;0.1966;White_Cedar;11;20.91;5.72;0.2233;White_Cedar;12;22.52;5.88;0.2263;White_Cedar;15;24.6;6.05;0.2293;White_Cedar;9;22.49;6.21;0.2323;White_Pine;10;20.54;5.72;0.2233;White_Pine;10;23.91;6.38;0.2353;White_Pine;6;13.26;4.58;0.2026;White_Spruce;4;20.52;6.21;0.2323;White_Spruce;4;23.47;6.87;0.2443;Black_Cherry;7;14.36;4.75;0.2056;Black_Cherry;6;13.23;4.58;0.2026;Northen_Red_Oak;7;13.76;4.58;0.2026;Bur_Oak;5;12.11;4.42;0.1996;White_Oak;5;11.49;4.25;0.1966;Paper_Birch;5;18.5;5.72;0.2233;Quaking_Aspen;2;17.23;5.72;0.2233;Red_Maple;4;17.97;5.72;0.2233;Red_Maple;5;19.4;5.88;0.2263;Red_Maple;12;23.13;6.05;0.2293;Northen_Red_Oak;30;30.39;5.88;0.2263;Northen_Red_Oak;45;37.85;6.05;0.2293;Northen_Red_Oak;38;35.42;6.21;0.2323;White_Pine;5;17.51;5.55;0.2203;White_Pine;6;18.8;5.72;0.2233;Black_Cherry;5;12.22;4.42;0.1996;Paper_Birch;7;19.15;5.72;0.2233;Quaking_Aspen;3;17.37;5.72;0.2233;Red_Maple;6;18.8;5.72;0.2233;Red_Maple;7;20.25;5.88;0.2263;Red_Maple;11;22.9;6.05;0.2293;Northen_Red_Oak;27;28.88;5.88;0.2263;Northen_Red_Oak;38;34.65;6.05;0.2293;Northen_Red_Oak;29;31.69;6.21;0.2323;White_Pine;11;20.24;5.55;0.2203;White_Pine;13;22.05;5.72;0.2233;Sugar_Maple;6;14.33;4.75;0.2056;Balsam_Fir;4;18.66;5.88;0.2263;Balsam_Fir;3;19.33;6.05;0.2293;Balsam_Fir;3;19.98;6.21;0.2323;Balsam_Fir;3;20.63;6.38;0.2353;Balsam_Fir;3;21.57;6.54;0.2383;Black_Ash;4;18.16;5.72;0.2233;Black_Ash;4;18.85;5.88;0.2263;Paper_Birch;4;20.33;6.21;0.2323;Red_Maple;5;18.24;5.72;0.2233;Red_Maple;5;19.3;5.88;0.2263;Red_Maple;4;20.32;6.21;0.2323;Red_Maple;4;21.33;6.38;0.2353;Sugar_Maple;8;19.66;5.72;0.2233;Sugar_Maple;8;20.67;5.88;0.2263;White_Cedar;11;21.11;5.72;0.2233;White_Cedar;13;22.74;5.88;0.2263;White_Cedar;16;24.85;6.05;0.2293;White_Cedar;9;22.66;6.21;0.2323;White_Pine;10;20.73;5.72;0.2233;White_Pine;11;24.13;6.38;0.2353;White_Spruce;4;20.52;6.21;0.2323;White_Spruce;4;23.47;6.87;0.2443;Basswood;6;14.26;4.75;0.2056;White_Oak;5;12.12;4.42;0.1996;" Many thanks, ---Jade ...

My generation just stops after a certain number of loops....I think it isn't related to the model size.

I just stopped using the models that are too big, but it still stops the loop after a few loops, I have no idea why.... ... View more

so I was able to use model that I downloaded online. However, they're too heavy. Each model is about 10-20 MB, and I have to generate hundreds of these. When I apply the rule, there's no error at all, but I notice that CE just generated a tiny portion of trees. The LumenRT's plant library is really light, I wonder how I could reduce my model size.. I tried to use cleanupGeometry commands but seems doesn't help. Can I do this quickly in CE? Or I have to manually import/export in other 3d modeling software ... View more

to follow up this question, scatter function does help. however, since clustering is a very localized effect, the plant distributor and plant mixer do not help much. The problem is I need thousands of plant clusters, each cluster has a specified number of plants, but the scatter function is global control. The solution I'm thinking now is to first scatter thousands of points, and then for each point, scatter the specified number of plants around it. But the scatter function doesn't take point object...do you have a better solution? --Jade ... View more
