Why does the loop cut tool go at an angle here? I just want it parallel. Is the only option the Plane Cut restricted to a selection?

Not understanding why the bevel controls aren't working. here

Hey Dr. Sassi,

I had tried both of those prior without success.

Apologies if I've asked this before, I likely forgot.

When sweeping a profile around a spline, say for a baseboard, often the result is inverted. Is there a better way to fix this instead of messing around with the axis of the profile itself?

What would be the best way to recreate this Apple Watch band?

I've tried tracing it with the spline pen to get the basic shape without much success. I've also tried making basic outline and then using the spline arc tool to get the overall shape.

Apologies for the late reply. I like the ideas but they don't work when used in the actual scene.

Awesome. I think the first option will be a good start. Thank you.

I've uploaded a section from the original scene with annotations.

Hi,

I have a Rube machine which I'm using dynamics to animate. On one section the ball gets stuck in a rail. The rail has a collider tag and is set to Convex Hulls. Setting the Geometry Accuracy to 10 on the rail will still get the ball stuck as the Rigid Body shape isn't leaving enough room for the ball to travel past. Setting the rail to Triangle Mesh doesn't work either as the ball just falls through the rail.

Any suggestions?

How can I randomize the rotation of objects in a cloner 360 deg but in steps of 90 deg?

This worked much better. In the end I used the splines from a Sub-D version of the mesh the geo sat much better against the bottle. Thanks.

Ok, thanks for that, I'll take a look. Originally I had tried to wrap Text Geo onto the bottle via Spline Wrap deformer but I couldn't get all letters to sit flush with the bottle.

Having a hard time unwrapping this simple bottle. However I try it it still results in distortion right where the two labels would go.

Thanks in advance!

Thanks, I'll take a look.

Hey -

I'm not able to get a consistent sweep along this spline as sections of it appear twisted. I've tried a rail spline but that didn't help either.

I saw a technique some time ago where you could use low poly objects in a cloner that were in a simulation (in this case, just dropping into a box) but the high poly version would be actually rendered. The low poly version was just used to speed up the simulation.

I've Googled around but came up short. Can you show me please ?)

I appreciate all your help

My response wasn't a criticism of what you had done, far from it, instead I was just relaying the techniques our tutors are using on trying to figure and model 1 point images without information.

This video shows how they accomplish this in 3dsmax.

https://www.icloud.com/iclouddrive/08d0uPXfm0As-0iPCNPZHMbIg#ONE_POINT

Thanks for your efforts here, I study what you did.

For some context.

This image is part of a visualization course in 3DSMax and in this case to recreate this scene. The whole point is to be able to match an image without known information like a floorpan, focal length and so on.

The first stage was to find the vanishing point and ensure it is in the middle of the image. To do this crops are added to the image to make sure the vanishing point is in the middle via rulers in Photoshop set at 50%. It seems if the vanishing point isn't in the middle the perspective match won't work correctly.

After that we have a grid overlay where each ground plane square is half a meter. So with this an approx distance can be calculated on the floor. Lastly, we try to find something in the scene that has a known size. In this case it could be the bar height which are often around 104-107cm or so according to Google. Bar stools are also often at a standardized height as well.

Where 3DSMax makes this process easier is in the perspective match tool. Once the image is in the viewport you can simply use the tool to drag the ground plane to where it should be. From there create a cube that matches the dimensions of something in the scene that you identified earlier, in this case the bar. So say a cube 104cm and 600cm wide. Using the distance and vertical adjustments of the perspective match tool, you can line up your cube with the bar until they match. Add a camera and set its height to around 120cm and turn on Auto Correct Vertical Tilt and that's it.

As I prefer using Cinema (I'm on a Mac) I was trying to camera match it with C4D and I found, like you, the process harder to do with mixed results. The focal length in your version of the scene is 90mm which would be unlikely. I have a 19mm and 45mm Tilt/Shift for work and the 45 would be way too tight for this shot, even if the images were stitched vertically.

When using the Camera Calibrator in C4D the focal length varied a lot, anything from 35 to 300mm lol. It seemed the vertical grid lines (y) were the culprit. Adding an extra line could reduce or increase the focal length. I also found it hard if impossible to get the vertical grid lines in the calibrator to be perfectly straight and they can't be snapped it seems. I'm guessing this one of the reasons why the pitch and roll of the camera co-ordinates wouldn't be at 0 and you can't adjust them.

I've included some screenshots so you can see what I'm referring to

I've tried a number of times to camera match this image and wondered if you could try so I can analyze how you did it? )

I had the match solved but I often found the focal length would vary. I also couldn't get new objects to "sit" on the floor by default. Lastly, the camera would often be a little pitched or banked. In 3DSMax you could set the camera to auto correct on the vertical for tilt shift which would prevent this issue.

Curious to see your result

I did some work on it:
