"Replace Objects" is a MaxScript tool that lets you replace multiple selected objects in your scene with a single chosen object. It keeps the position, rotation, and scale of the original objects, making it ideal for swapping placeholders, optimising assets, or quickly replacing geometry in bulk.

This script is completely free to use. If you'd like to support the author, you can purchase the extended license!
