Frost/snow on top of cut hedges
« on: December 06, 2023, 05:05:33 PM »
Hi All

I'm wondering if this is possible as the leaves are not one object & while I suspect my method is working it's affecting the entire scatter rather than the top only (masked with a gradient map).

I can make snow/ice appear on the top most polys of a tree using the Z-world falloff (towards/away) & a gradient map (as mapped source) (See example image attached).
But because the cut hedges are multiple objects scattered it doesn't work the same.

Is there a way I can achieve frosty leaves on only the top using a gradient or other method?
Hope this poor explanation is sufficient.

Best regards
Chris

Hi Chris,

It should work in a very similar way for hedges as well. A possible setup would be to use the Planar from World XYZ mapping for the Gradient map to target only the top. I hope that helps.

Hi Michal

I'm unable to replicate using the cut hedge materials.
Would you be able to provide an example?

Thanks.

Hi Chris,

Sure, please find attached a sample scene (IcyHedges_iToo.max), and the used material (IcyHedges_iTooMat.mat) showing the possible setup. I hope that helps.

Best regards,

Sorry Michal

Just one more question. You used the fixed size path distributed hedge.
I want to use the cut hedges for creating topiary shapes (e.g. scattered over objects). These will all be different sizes.

So fixing the size to 2.2m (as you used) does not work. It simple repeats on the taller scatters if I scale for the smallest.

Sorry to be a pain.
