Hi Kouraib

thank-you – that is a good working solution. If you have time to find the cause I would be interested, too.

I have used the known technique of selecting all edges in an object and saving as a selection. Then including that tag in the applied Sketch style. But this is not working in my example object. Am I missing something?

NB struggling to upload c4d file

here’s a link

Looked through an xpresso in detail book that I remembered I had, I started to realise that this is most likely a Python task. I will direct my attention to some experiments in generating objects and setting their parameters with Python, that I played with some time go.

Can I use xpresso to loop through large numbers of Field Force objects and set up the paramaters I need.?

For example I would likw to

1. Set a spline in the Field Lists

2. Set the paramaters in those spline fields.

3. Assign particular Field Force objects to the ‘Include’ lists in particular emitter objects.

Trying to get started with this, I see that…

Thank-you for showing us your technique. Very interesting method. I think perhaps the amount of adjustment by eye is probably equal to what I am doing with look-at-camera tag and nudging the spline inside the null. I went for that latter method yesterday for my final version, and it worked quite smoothly that time.

I will certainly play with your…

After some more experiments, I think I understand this better.

One of the important things is that if the object is off-axis (on any of the 3), then the resulting exported outline spine will not be in alignment once re-imported. It will also be flipped 180 along the x axis – which in itself is easy to fix.

The solution I have found is to add a c…

Using the Look-at-camera TAG goes some way to a solution, but the object is flipped 180 degrees, and even when corrected it still has to be aligned by eye.

Example that makes clear the 180 degree flipping

How to align an object’s exported outline spline with the original object in camera view?

1. Export the sketch and toon outline to an .ai file

2. Reimport it to c4d and then copy spline to original project file.

a. The object is 20 times smaller than original. Easy to fix.

b. The object has correct perspective in front viewport.

How to align it to the…

It works thank-you!

A couple of points for anyone else trying this.

a. Exclude the turbulance field from the moSpline – otherwise the destination spline (the on neing used in the field forces will go crazy. I excluded all the forces for good measure.

b. The MoSpline appears to be destructive, as the original spline cannot be restored even after r…

Hi Kouraib

that’s amazing. I just tried a simple example, and now will try it in my full set-up.

Thank-you!

Hi Kouraib

thank-you. I think I was typing up my post as you posted yours.

I’ve not used MoSpline and not totally sure what you did there. Did you turn the first Spline into the second spline Spline.1 using MoSpline?

I’m all for easier solutions! I need to look at MoSpline.

I have worked out what is going on here. There is a problem using structure manager to copy and paste spline points from one spline object to another spline object fails under a specific circumstance. A circumstance I did not identify in my opening post. This applies to versions r25 and 2023. And there is a work-around.

The PROBLEM is to do with…

I have an existing spline A used four times in three different field force objects. Emitter Particles follow the spline. The force objects’ spline layers all have custom settings

I want to replace that spline A with a different exisiting spline B and retain all settings in the force objects.

If I connect and delete spline A with the new spline B,…

Thank-you. I think that I’ve worked out that Strength and Contrast have the most effect.

I’ve gone back to Sketch & Toon with better results than I was getting with Hair Material.

Some playing around and some very extreme settings. I’m not sure I totally understand how this works, but I include the property settings for anyone interested.

It’s quite close to my manually created mock-up further back, although I’d like to try and further…

Well here’s what I have. The ‘blobbing’ is a bit angular. But it’s a start.

100 splines made by particle paths, might be the problem. Labour intensive.

I’m looking at Hair now. It has noise applied to thickness/texture. I’m finding it hard working through the options to get the same effect, but I’ll give it a go.

Yes – I dont think that will work. I need to render splines made by particles using the Tracer. And the rest of the objects in the scene will need to be rendered using Sketch and Toon.

Here’s an image to show the kind of effect I need. (I roughed this up with splines and sweep and displacement.)

Hi Kouraib

thank-you. Yes that’s much closer to what I need. I’ll have a play with it.

I suppose my main question will be – can this be applied to splines generated by Tracer object?

Rumination. Maybe this can be approached more easily in xpresso nodes that operate on the material’s thickeness property.

Q. But how could I change the line thickness as a function of a position over its total length?

I’d like to vary line thickness (in a Sketch and Toon Sketch Material) artbitrarily so that I get an inconsistent (gloopy) line – like the kind of thing you’d get with a hand-dipped ink pen.

I’ve tried the Random option (noise strength and scales) and it does not seem to do what I need.

I wonder whether I can do this in Python, but cannot find any…

That’s correct. All work done directly in C4d.

Kouraib, thank-you for your reply. I get that the changes made by exporting and reimporting to-from Mixamo may have been a factor, but it does not explain why one c4d project works and the other does not – before Mixamo is even involved.

regards, simon

I have since worked out the missing step in my figure project, was to export the figure to Mixamo, and after setting a walk animation there, putting the figure back in c4d, where the reset bind-pose now worked.

This does not explain why it worked in a simple project but not with a more complex figure project in c4d – before the application of…

I have used an off-the shelf free figure rig (thank-you, ace5 studios) and reskinned it. Bind command, then Autoweight. I move an arm and then press reset bind pose. Nothing happens. I had this working with the same rig last week, but now it does not work. I cannot work out what the difference is.

I made a simple second project. Added joints to an…
