Размещение объектов на не ровной поверхности

Nikkus · 3 фев 2011

Имеется плэн, с некоторым рельефом и большое количество домиков. Как их разместить на этом плэне чтобы они стояли на нем, т.е. в зависимости от изгиба и высоты?

Есть огромное количество скриптов на данную тему. А в 2011 этот инструмент вообще встроенный (и функциональней всех встречаемых мною скриптов).

Вот мой любимый для 2009-го. Его используют в уроках 3D_Palace

я скриптами никогда не пользовался и не представляю что делать с выше значимым
у меня 3дс макс 2010

wallpapers free, youtube

Александр Чернега · 3 фев 2011

Выделяешь и копируешь весь код, вставляешь в блокнот и сохраняешь. Потом меняешь у файла формат с txt на ms (переименовываешь). После чего бросаешь его в окно макса. В настойке ищешь категорию "paint", после чего, либо выносишь на панель, либо назначаешь горячую клавишу.
И еще один вариант, как можно впихнуть скрипт в макс http://www.render.ru/forum/viewtopic.php?post_id=886002#886002 (сообщение 13)

Где сейчас расположенны эти дома? Изгибы поверхности очень большие (крутые)?
Дома находятся над поверхностью и их нужно просто спустить вниз на поверхность?
Если поверхность была бы ровной, тогда ты бы разместил и раскидал эти дома вручную?

Turnado · 6 фев 2011

А где в 2011 максе встроена эта функция?

Александр Чернега · 8 фев 2011

Посмотри любую сборку видеоуроков о новинках 2011 макса, там должно подробно рассказываться как этот инструмент работает.
