red51 - i appreciate your answer, though it was exactly as i expected. I understand fully why you think about this. But i still think its not the Rising-World-way. You put so much efforts in making it realistic and immersive. But with reshaping a block out of inventory you open a can of worms, believe me.
Soon players will come and ask - why can i change a concrete block in my inventory from square-shape to a triangle but i can´t cut off the arms of my long-arm-shirt (sorry, don´t know the right expression) to a tshirt?
Being able to switch the blockshape inventory is convenient. But other things are not. So there will be a descrepancy between this process and others. I wonder why that should be. Why to use an anvil to create plates and poles out of a metal bar? Or if you have these parts, why do use a Tier 2 workbench to assemple them?
I wrote im surprised about this approach. I am because it doesn´t fit in to the usual concept of this game. And honestly, i seriously doubt anyone was ever about to abandon the game because he constantly mis-clicked the shape of a block. Yes, it might happen but really that often? And even if, stone and wood is available in abundance. Mining even just one hour means to have at least a full chest with stone (depending on the tool you use). And i think the new version will be similar. In the end there is stone everywhere and wood is, thanks to planting trees, also available almost everywhere.
But as it seems some people are interested in this feature, maybe its worth to consider a compromise? Like a tool (wood/stonesaw, chisel, etc) to be available in an equipment slot of the inventory in order to be able to change the shape. Or maybe a mobile recycler, that you can hold in your inventory and when needed just place it in front of you and when aiming the block at it you can change the shape. Thats still not what i personally think it should be but i guess thats part of a compromise.
After all you do what you think is right. Until now you didn´t disappoint me with this game, its by far the one i played the most - ever.
