    for my projects.

thx, glad to hear.

Sure newbprofi, that’s why we give you source access :slight_smile: If you need to make improvements feel free to send us the pull request. Maybe it’s worth making that improvement for everyone so that you don’t have to maintain the change and deal with the merging.

I want to add that, if you make changes to any of the Engine code and we don’t merge them back into our main branch, then any modules (including those for plug-ins) that you create to be used by other developers and that depend on these changes may not work or compile unless these other developers also apply your changes.
