One fir tree looks much like an other fir tree. You’ll only need to rotate them a bit each time to give them a slightly different profile and maybe alter the size a few percent.
Ideally, you could use the Instance Lab to do all that for you, but if you try, remember to save your work at each stage as the IL can be a bit unstable.
Also, with the tree I linked to, the fir needles are separate from the branches and the snow, so you can select the needle mesh and alter the colour in the material lab, maybe making the smaller trees a lighter green colour.
Thanks, i’ll give that a try. And I shall be honest - as a novice, I seriously doubt if I’d have thought about instancing.
Regardless, I’ll post it in the WIP section as soon as I get a preliminary scene set up.
