New leaf mesh

Recommended Posts

Hi,i hope Exlevel team can develop a new leaf mesh type ,to solve some special leaf type ,just like cleft leaf  and lotus leaf. i know some people use opacity map to solve.but i think most people don't like use opacity map.that will slow down render.

This is what i thinking.

Ok, we'll think about this...

For better control, I think we can try to implement something like a MultiPath mesh builder. That is, new mesh builder will be based on multiple paths that start from the same point within a Distributor in point.

 

See my screenshot to see what I mean:

It's my old idea, thanks for reminding me! :)

 

Cheers

my stab at it :) you could use two paths to define leaf shape and use looping to subdivide so that the output is quad. this way you could add a mesh smooth without odd pinching.

 

update: where the loop cuts a triangle at the top and bottom you would need to divide the segment to keep quads.

 

if this is ridiculous I apologize. I have no idea how to program :)

 

another update : I just looked at my sketch and realized it can already be done like this with the existing leaf mesh editor

Hi Paul,

 

Of course, it's difficult, but we'll try to implement it...

Thanks!

Sure, i think the steps of path need to be improved. add a average control. it's control by distance now.  If i add a chaos value,it will shows a different steps

 
Usually the length of steps along path is the same, and if you add a chaos value, the last segment has a different length, as in your case.
I think the new leaf will not be use the length of steps, and will calculate the polygon size based on their own parameters.
 
Cheers
