Question

Use an image to drive x/y amount in tile sampler

Is it possible to have an input drive the x/y amount of instances in the tile sampler?
As my instances get smaller, i want to increase the density/amount


Do I need to use a pixel processor function and some fancy math for this?

Thanks!

Hello David,

 

You may set the Amount parameter to the value matching the highest density in the map, then use a combination of the Scale map and Mask to control the number and size of shapes along the map.

 

 

I hope this is helpful!

 

Best regards.

Thanks Luca!
That makes sense, but I must be missing something...

I tried to recreate your example setup, but not sure what I am missing.

Hello @David Conlon,

 

Increase the X/Y Amount values, then increase the Mask Map Threshold value. The latter value determines the level of gray in the mask below which shapes should be masked.
Currently, the value of 0 means no shapes are masked since none fall into a value of exactly 0 in the mask.

 

From there, tweak the Scale and Scale Map Multiplier values to control the size decrease and prevent gaps.

 

Best regards.
