That is a great idea! I was looking for an excuse to look into multiplayer stuff. Might do exactly that as a practice. Thanks for the feedback!

In case it is not clear still, I will put here a couple of gifs of the feature and an extra explanation :)

When you place a block (any block) it will be placed following the grid and snap to the the center like so: https://gyazo.com/20aee426492f975d80df9c839e788dc4

BUT, if you hold G while that is happening (before left-clicking with your mouse to place the block in the scene) the object will snap to the surface normal of anything your mouse is over. Like so: https://gyazo.com/7878c0d63f0c37c641a3888d8e7c1e1d

After an object is placed on the scene you will be able to move the object using the gizmos (axis/arrows) like you would in any other 3D software (Unity, etc...). At this point G will no longer be used to snap the object to the surface of other objects but instead to group blocks together to combine them into a single object. (Can be undone by pressing CTRL + G). (Like parenting if you like to think about it that way)

Hope this helps :)

I'm making it from scratch in order to get a better and more extendable result since last time I had little time to make it.

Will post it here as well once I have a decent demo :)

Cool! Let me know if it does work. At the time I didn't have any vive devices to test it.

I have not tried it with steam VR but might work as is. Either way I'm working on making it specofically for index now that I have it and add new stuff and fix old bugs.
