Hedgerow Rendering in 2023

[Christine Mulinder]

I am using the hedgerow tool in 2023 and I'm having problems with rendering a curved shape. If I create a straight hedge it's fine. I've tried by class or direct texture and it makes no difference and I've also tried changing the mapping types in the OIP and still no change.  Where am I going wrong?

[Pat Stanford]

That looks like a difference between Plane mapping (where the texture get's "extruded" along the sides of the object and Auto-Align Plane or Surface UV mapping where each plane get's a "head on" view of the texture.

 

I have not used the Hedgerow so I don't know if it uses that or not, but check the Render tab in the OIP and see if it is set to Plane mapping.

I checked + no matter what mapping type you choose the effect is identical. There is zero difference between any of them.

Hi, right now the best way to avoid this is to use create object from shape.

Instead of drawing with the tool, draw the line as a polyline. Then simplify the line so it consists of segments instead of a curve. You won't loose any quality doing this.

Then, use the command Create objects from shapes and create the hedgerow.

When you then add the texture, it will look perfect, see the difference below.

When the hedgerow becomes a style, we can add the simplification into the object (like the landscape area tool).

Or, you can of course just draw the hedgerow line in small segments by hand, if you prefer that.

Thanks all, I'll try out the suggested solution and report back

How do you do this?

 

I can get this...

 

 

... if I draw the 'circles' using the Regular Polygon Tool (i.e. 'Hexagon' Tool) then add them then convert to Hedgerow.

 

But if I instead draw four Circles then add them together is there then a way to make the shape facetted before converting to Hedgerow? This is what four circles added + converted to Hedgerow looks like:

 

 

Is there a way to draw curved Polylines then make them facetted or do you have to draw the 'curves' as a series of straight lines with corner vertices from the outset?

 

Thanks

Hi @Tom W., draw your polyline/other object, convert it to polygon (Modify > Convert > Convert to Polygons), then use Modify > Drafting Aids > Simplify Polys.

Then test so you find a conversion that suits the object.

Doh i was missing out the convert to polygon stage thank you!

Got it now thanks for your help

Is this imminent? And this will basically have the effect of converting the Polyline into a facetted Polygon automatically from the OIP? So you can draw a curved path as a Polyline then just adjust the Simplification Tolerance in the OIP to quickly make the object facetted + therefore render correctly?

[Katarina Ollikainen]

@Tom W., I don’t have a date for this implementation yet. 
However, it will function like the Landscape area - it is a reversible simplification, set for each individual object in the Object Info Palette. Try it out with the Landscape area and you’ll see how it affects the object.

Hi @Katarina Ollikainen thank you yes I'm aware of the setting on Landscape Areas + Hardscapes (in fact it was you who pointed me in the right direction when my VW2022 Hardscapes suddenly looked horribly facetted in VW2023). This will make a big different when available for Hedgerows too. Thanks for your help.
