Can you render internal lines with toon material?

As the title says, can internal lines be rendered, or it is solely outline?

Never mind. I worked it out. I was using cylinders as tests and the angle different was very low. So I had to Turn Normal Threshold to 0.99 and Overlap Threshold to 0.01 before I could see the effect.

Re: Can you render internal lines with toon material?

The success of internal lines with the toon shader depends largely on the shape of the object that you're rendering. With an object like a cylinder, there really shouldn't be any internal lines. The settings that you've adjusted will make internal lines more likely to appear, but at those settings, what you're probably seeing is artifacts along edge of adjoining faces. For a cylinder, this may be fine, but for something with smaller faces, it may not be as "fruitful"

Re: Can you render internal lines with toon material?

that was what i experienced too. I tried to render a curve & got all the lines between the surface. Thom, great that u brought that up. I'll definitely give it a try. But i couldnt find the overlap threshold...could you give me a direction here??

also, sometimes when I tries to render a ground surface. the material shows up in a irregular orientation....which it supposes to be one seamless piece of texture. When i turned on the hidden lines, it looks like the material got screwed up from one sample to another sample. the materials changes orientation. Do you know why? & how to fix that? thankyou very much!!!

The overlap threshold is next to Normal threshold in the material properties.

I'm not sure what you mean by material orientation. For Toon lines? Or are you referring to normal materials with textures here?


What I did have some problems with was getting the Toon lines to look fine in Reflections. They ended up broken up no matter what I did.

Thom..please take a look @ my renderings...the area circled red is what i meant...same texture, but shows up 2 different colors





& the toon line issue...there will be no way to fix that. rite?? too sad....what i did was i set the sides of the arc in Sketchup like 96, then the toon lines are gone in the reflection. But the rendering time takes longer. But i guess there is no easy fix in Vray. i am sorry. Thom. I only find the normal threshold under the IR setting. i couldnt find the Overlap threshold in the material property....do u mind post a sceenshot for me? thankyou!!!

Re: Can you render internal lines with toon material?

The grassy material issue you have there is due to the geometry. It's not welded properly. I see form the SU view that a couple of lines are not visible. Indication that something isn't connected properly. Turning on Outline in your SU Style is often useful to spot areas like that.

Toon lines can't be smoothed. They have to all be hard edges.

The overlap Threshold is not in the VfSU options, but in the options for the Toon Material. I can post a screenshot when I get home.

Artchung,

Can you confirm whether you have hidden geometry along the edges of that triangle? I have seen similar problems with two of my VfSU models, but there is definitely no hidden, smoothed or coplanar geometry there. It's only when you run the IM pass that you see VfSU placing many times more samples along a line or across a triangle than normal (set IM Maximum to +2 to get a good screenshot of it), indicatating that there is some problem with how SU is creating that plane and how VfSU is parsing the geometry. It typically happens when you have an L-shaped plane or any plane that has an internal corner- SU creates weird triangulation from that internal point. Obviously triangulation in itself isn't weird (i.e. 3DS geometry), but this is definitely an anomaly in SU/VfSU as I've only seen it occur twice.
