I’ve also started my Trees image… I have plans for using the Instance Lab for placing trees in rows along a hillside… I watched the Bryce 7 Instance Lab tutorial, but I didn’t see how to instance in straight rows… Is there a way to do this?
Sorry, I didn’t have time to answer this when I saw it earlier.
The answer is “yes”.
But understand that trees are grouped objects and as such don’t instance easily… I think there are ways to cheat it but they are complicated and you’d need someone who’s got more experience of the IL than me to explain how to do it.
But as what the Instance Lab creates aren’t actually instances, you would most likely find it easier to use the Multi-Replicate feature instead, though that then has the disadvantage of if you needed to edit the trees you’d have to do them individually whereas if you use the IL, you can simply edit the master tree (your original) and it will apply the changes to the others.
So to make a straight line of trees in the Instance Lab, first create your terrain and then create a tree.
Select the terrain and click the button in it’s little floating menu… This opens the IL.
Go to Brush Editor and select the tree you’ve just created from the drop down list in the Brush Component box (you can set the variations in size, but as far as I know, the rotation one does nothing regardless of what parameters you set) as in Picture 1
Then go to the Painter tab and using the Plus button to zoom in or out of the window until your terrain fills the window.
Use the basic settings in my Picture 2, though you may want more trees or less trees, so alter the Density setting to the number of trees you want in your row. And you may also want the row to be shorter or longer, in which case alter the Size setting to your desired size.
When you are ready to paint your row, only click on the paint area once and make sure you also press the Control key at the same time. This will ensure your trees follow the contours of the terrain.
Once the IL has done it’s job (sometimes it can take a while, but don’t be impatient with it), Click the tick to exit the IL.
If you are happy with the result, you’re good to go, if not you can use undo to undo what you’re just done (it takes two undos to get back to the point just before you entered the IL originally.
Don’t be tempted to alter anything within the IL as it is much more likely to crash if you start adding multi layers of instances or deleting several instances without first exiting the IL and saving your file.
I’ve done two rows of trees here, I did one row, exited the IL to check and then re-entered the IL to make the second row (remember that when you re-enter the IL, you also have to remind the Brush Editor what it needs to instance).
Hope this helps.
