масштабирование объектов в режиме выживания

As I know Construction Elements will be possible transform up to 5x5x5 units, and other objects like furniture are in range ~0.8-1.5. In creative their size can be between 0.01 and 32

We've been thinking about that in the past. It's true that it's basically possible to get an advantage by using larger construction elements (and therefore require less resources)^^

On the other hand, it may feel a bit less intuitive if resizing depends on the number of blocks you have in your inventory... for example, when resizing the block to 5 x 0.05 x 5, it would still require ~ 1 block, but if the player only has a single block in his inventory, he couldn't make the block thicker in this case (unless he reduces the length or width).

It is also a bit restricting when building with large elements in general, so probably it would still be reasonable to use smaller blocks, even if that's a bit more "expensive". Unless it's a rare material (iron, gold etc), it probably doesn't matter that much (considering it's easy to get stone or wood)

But once the world gen update is ready, the survival part may play a bigger role in general. We will keep a close eye on this, and if it turns out that the currently resource handling is indeed too unbalanced, we will definitely change that
