I have a question about redshift materials in the viewport: When I use metalness in a Redshift material it looks good in the material preview, but in the viewport it looks like it is only all reflective. Is there a setting I'm overlooking to change the viewport material preview? Or, is there a way to just use the color channel for preview, similar to the C4D standard renderer and materials?

@Cerbera Yes, it's better than my first version, thanks for that. The biggest issue I had was around frame 170 the head turns almost 90 degrees and stays there and that still is there.

@CerberaThanks for looking at the file. It still rotates and randomly twists, though. @HappyPolygonThanks, that helped me come up with this solution that seems to do what I want: I didn't use an instance object to clone the spline, but a MoSpline, with mode set to spline - I moved that upwards and used that as a rail spline in the Spline wrap. - Then I disabled the "rotation from rail" in the Spline wrap. It seems that it still uses the up vector for orientation, but it looks better on very vertical movements on the spline. Now it uses the dynamic animation but with (more) manual control over the twisting and orientation of the object. I'm not sure if this will work in all situations, but It's great for the thing I'm doing. snake_dynamics test2.c4d

Thanks for looking at it. Around frame 170-175 there is a turn that turns the head about 90 degrees. and I'd like the whole belly of the snake (green part) on the ground. It now twists along the spline

I have a dynamic spline and want to use that to spline wrap a snake on there. The snake is now rotating (z-rotation, along the spline) around the spline in ways that I seem to have no control over. I can't find how to control the up vector of the spline. In this case I would be happy if it turns upwards always. - I know it's possible to control rotation with a rail spline. But I have no idea how to get a rail spline working in an animated/dynamic setup like this. - I know I can control the rotation in the Spline wrap, but at the moment it is too erratic to counter-animate. Is there a way to get some more control over this? (C4D 2023.2) snake_dynamics test.c4d

Thanks for checking. I'm using C4D 2023.2 - The red border is because automatic keyframing is enabled. I attached a version that works in R25. Polygon selections on parametric objects is a recent addition. TP_test_R25.c4d

It's been a while since I've used thinking particles. I might be overlooking something. I'm generating Thinking particles with the matrix object. Is it possible for those particles to be affected by the wind, attractor, field force etc. Like the standard particles? Those forces together with fields are much more convenient to work with than the TP counterparts. TP_test.c4d

I'm not completely sure why, but it seems to work if you group everything inside a null object pose_morph_psr_v2.c4d

Ah yes, that is an excellent question. I am applying the pyro to the fragments. It looked like the smoke didn't inherent the speed from the fragments, though. So the smoke would originate from the place of the fragments, but not move with the direction of them. There is an option for velocity from movement, and if I set the strength high enough, it seems to do what I want. The smoke it following the fragments Thanks for pointing me in the right direction

I'm trying to get the pyro to work as dust/debis/smoke for a breaking simulation. The way I got the smoke to follow the direction of the fractured parts is with a field force that is linked to a tracer object that traces the fractured parts. This works for the most part. As far as I understand this now is that the field direction comes from the tracer, but not the speed. Does anyone know how I also could get the speed of the fractured parts into the field force? I'm not even sure if this is the best solution for this, I'm experimenting. break-smoke-test.c4d

Have a look at "Time track" Maybe that is what you are looking for.

Seems to work here. Please try the attached project and see if that works on your system I'm in C4D R2023.2 timescale.c4d

Start by freezing the rotation of the bones. It's easier to control them that way. 1: You can then use xpresso to link rotation of the joints. 2: With a bird like this and this relatively simple joint setup. It's not that hard to animate it by key frames. Then you will also be able to offset the animation for a more fluid movement. 3: For a cyclical animation like this, it's also possible to use Cmotion for parametric, looping animation. It's a bit harder to set up if you've never worked with that, but re-timing and changing offsets is a bit easier than with key frames I've added a project with these options bird flying_v2.zip

Without a project file it's hard to pinpoint the problem. Are you using the Character object with the Mixamo control rig? Joints don't need to be in the same hierarchy to work. You can try attaching the extra joints with a constraint tag and add them to the weighting tag manually.

I don't have Arnold for C4D, so i can't check this myself. Colors like that can be make with Mograph field colors. This tutorial shows how Arnold can render field colors:

Here is a simple setup, I hope that helps. - I made a cyllinder, added 3 joints, bind them together. Added 2 keyframes to make it easy to check if its working. - Add muscle object. Set 2 anchors to 2 joints. Then placed the 2 endpoints of the muscle object so that the muscle is inside the geometry, and at a logical place. Fiddled around with relaxed compresswed and extended settings ( I disables autovolume and used the set button in extended and compressed states at different times in the animation) - Added MSkin after Skin object. muscle_test.c4d

You can put the cloner in a connect object, and then use one vertex map on that.

Thanks, That make it clearer for me how that works in the node system. I have a followup question: Is there a way to use a vertex map information to control the poke offset? Or anything other than the iteration index? I'm now using a noise with the iteration index as seed to make some variation.

I love this answer. I'm not very good at understanding and using nodes yet, but as far as I can see now they do have a different usage than Xpresso. I do hope Xpresso stays around. I love where capsules are going, they are such a great addition to C4D. I do think the new nodes system has some ways to go yet to be user friendly. For instance the range mapper in Xpresso is from a user standpoint much more useful than the capsule/scene-nodes range mapper node

Could you upload a scene file? I'm not getting that behavior on my end

Maybe this helps: I've made a point object (empty polygon object to which I added points manually). The deformer makes it into a sphere. Cloner object to put spheres on each point. If you want precise control over all the shapes and sizes, you can make as many child objects as you have points and edit them individually a Xpresso setup to move null objects to the position of the points that you can use for exporting 3d data. Chart-10_v2.c4d

I don't know for sure if you can set an objects layer in Xpresso, but I don't think you can. For your 2nd question. You can animate the Enable-tick on the Xpresso-tag, so it only evaluates on the frames you enable it. Or you can make a 2nd Xpresso-tag that controls the enable-tick of the first one with some kind of rule.

A work-around is to make a second cloner that uses the 1st dynamic cloner as input. It will copy the positions/rotations of the dynamic cloner, but all clones are then also influenced by effectors. Clones dynamicwith target effector.c4d

I'm using a Geometry Modifier Group. AFAIK that is a generator/Deformer that you can program with Nodes. I think the question also applies to scene-nodes. I'm wondering if I could use a field to steer the Offset value of a Poke node (for instance) I'd like to control the offset of the poke per polygon with a field. I know in Xpresso you can iterate over all polygons, get their position, then get the value of a field at that position and then do something with that information. I'm trying to figure out if the node system also can work like that. And if so, how (I'm using C4D 2023.1.3) poke with field_.c4d

I occasionally have that. IIRC it happened when C4D crashes. It does not happen often. I don't know what to do about it except kill the process
