**Hey guys! **

I created a plugin:

A simple example:]

But I want to ask one question.
For improvement, adding new features, support new versions of UE4 I need some profit.

If you are interested in a plug-in what you would select:

  1. To make a plug-in free. Donations can
    to pay for work on the plugin
  2. Use
  3. Use MarketPlace, and nothing else!
    And Please write your answer here

Can you reduce draw calls combining meshes and reduce collision costs by grouping similar neighbour meshes ?
If i should buy it it would be through MarketPlace because you get better support for plugins than Gumroad.
