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.

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:

Thanks for that. Interesting solution but a bit more involved than I was hoping for.

I think I can make it work using the tile shader along with noise to drives bevel/grout width.

I'm looking to add erosion to the edges of some floor tiles, i,e, where edges have been damaged or chipped away.

Any suggestions on how to approach this?

https://www.icloud.com/iclouddrive/02bITTu-U0TcFAe-VOVyGnAPg#tiles-grout

Thanks. Not really because lining that up against multiple walls which could face many directions is just to time consuming.

Do you know anything about the Partition Modifier in the Asset Browser? It's a Maxon One modifier which I don't have so I can't try it. Does this not generate floor geo?

Is there a fast way to model bricks on to multiple wall surfaces?

I made a brick pattern using a spline mask, first part the bricks in a cloner and the second a spline to constrain the pattern to a shape. It works fine on a single surface going in a single direction, but it's a hassle when you have surfaces that are facing multiple directions.

In 3DS Max they have a floor generator script that does this very fast unfortunately.

That's so cool! Totally forget about volume builder. Should have thought of Boole to. Thanks for the suggestions!

I've been trying to create the shape in cyan unsuccessfully.

I've tried a large bevel on the corners of a cube which sort of works. I've tried a loft with a circle>rectangle>circle but the cube was closer.

I have an object with a displacer as a child, and the object is then added to a cloner.

The displacement is the same for each clone because the noise seed is the same. How do I get a different noise seed for each clone?

Oh I get it, managing that much material which is constantly evolving is sure to be a challenge. I think it's great that the Maxon team are active and adding material.

If I could add a request it would be for more modeling tutorials, guides etc. For example if I search for "loft generator" on Cinversity there are only 10 results, and of those none are relevant. There is a great series on Cinversity by Edna all about Deformers, the same again about Generators would be great. For now, I'm stuck mooching around YouTube.

Although I've mentioned it before, you are an incredible asset. As I'm learning I often have specific questions that a tutorial just doesn't cover and I know if I post here you always provide a prompt solution which is invaluable to me. So again, thanks for your efforts.

I have to add here that the current Cinversity site isn't that useful. There is good on content on there but finding it is a challenge.

Whilst the material added to YouTube from the Max Training team has some good topics, just wading through those videos is very time consuming. Typically they are at a minimum of an hour, often more. Personally I find the quick tip videos the most useful.

A little annoyance is that if you've searched for something and have paged through a number of results, say to page 9, if you then do a new search you are not returned to the first page of the new results, in this case, you would be still on page 9 of the new search results. Hope that makes sense.

Perfect. I did originally duplicate the original tracer for a rail but what I missed was a set of nulls for it. Thank you!

I have a profile which I'm attempting to sweep using a tracer object as the spline. It works but I can't seem to find a why of changing the orientation of the profile. Currently it's being swept vertically when I need it flat on the ground.

Amazing. I always forget about the Loft but this looks great. Thanks again Dr. Sassi.

Thanks for the prompt response again!

Ok, so I had tried the rail spline with the projection as well

A few questions:

1. What is the purpose of the Scene Node Geometry Axis? Where does that come from?
2. The effect works when there is some thickness to the sweep, but say at 1cm thickness it fails. Is there a way around this?

Hey,

I have a spline projected on to a surface with is then swept with a profile. It works but not all parts of the sweep lie on the surface.

Any advice would be appreciated!

Perfect. Thanks so much!

I need to create some lightening bolts

I've tried using a tracer linked to a couple of objects but couldn't figure out how to get the branches of electricity coming off the main bolts.

I saw the new particle branching scene in the asset browser but don't know how to just get straight/jagged lines like in real life.

I don't have access to Maxon one, so can't use the Electric spline node.
