Can AM Rendering Taper Lines?

[Tom]

I am aware that AM toon render can control the thickness of the line.

 

Can you also control that line so that it is possible to taper it from one end to the other?

 

(see attached graphic which shows a line created in a graphics program and some curtains which were rendered in AM)

 

Thanks for any feedback!

If you crank up the "bias" you can get a more elegant fade-out without the widening of the line.

Here is something I've been meaning to try for years. Higher Bias settings make the line end a bit sooner than lower bias settings. By rendering with three different Bias/Thickness combinations and then compositing the three versions in Photoshop with the "Darken" mode we can get something that resembles the hand tapered line of illustrations...

Fantastic!

 

Thanks Rob!

Here is a turn-around test of the compositing method. It's a modest taper effect, but it is a taper!

Cool!

 

BTW- I tried playing with Bias but it only lets me set it to 100..and no higher...

 

Can you explain the trick?

 

Many thanks!

I was able to set it up to 1000.

 

What version are you using?

[Tom]

18.0h SSE4 64 bit.

 

Attached is a picture of the interface:

 

thanks!

Interesting. You are setting it in the model or the material? I was setting it in the render settings.

 

The limitation may be a bug that needs to be reported.

I was setting it in the model settings....Toon Lines etc.

 

in the render settings it works fine.

 

many thanks!
