Hello,

I recently encountered this error after trying to import an OBJ sequence into Particular. I've imported OBJ sequences successfully before in exactly the same way and never had this error. I had gotten as far as setting things up in designer view, the error popped up when I hit the 'Apply' button. I haven't done anything different to how I've done it before so don't know why this has happened? Any ideas?

Kind Regards
David

Hi Dr Sassi, with a better understanding now I went back to my own experiment and had much greater success I see better now how it works Just one quick question though, I could not see a cog wheel on the export window in C4D? I can only see this;

Kind Regards

Thanks Dr Sassi, I think I get it now and thanks for your patience. I'm very new to 3D so I'm still having to get to grips with the core basics here. It helps greatly to know that the OBJ sequence is just the geometry, I hadn't realised this. The OBJ is like a raw ingredient, with everything else handled by the application it is put into? Reminds of text in way, like how in InDesign for example, you can format a page of text with all sorts of styles and give it a graphic layout, but if you opened it in a raw text app you see only the words and no formatting or layout, is that the right idea?

Aah I see (I think), so the object is exported as a single entity all on its own with no camera information?

Kind Regards

Hi Dr Sassi,

I'm sure I must be missing something simple here but I just can't seem to export out an OBJ sequence from the camera view, they always come out from the front view.

I was following along the 'Dancer To Dust' tutorial as I want to make good use of these sorts of techniques, of using 3D models in the Trapcode suite. For my first attempt I have a very simple scene of an object flying through the air spinning as it goes. I have a camera that follows it as it whizzes past. However when I export the OBJ sequence so that I can then bring it into Particular for a user 3D object to emit from, the whole animation is in the standard front view and not through my camera view. What am I missing?

Many thanks
David

Hi Dr Sassi,

Thanks very much for the advice. The way that Mr Noseman does it in that 'Ask the Trainer' series is very similar to the way I was going about it. I guess I was looking for a way to make all the bends and folds with the thickness already applied, (as it would be in real life). I will explore the tension tag and experiment with that to see what it can do (haven't had tine this week because of workload) I'm okay with the graphics side of things as I do packaging design regularly for years now, and like yourself I've never needed to compensate for stretching. The materials we print on are quite thin so its never been an issue. At this stage I don't need to animate it however I'm thinking that when I have it all setup it would be great to have the option to do so at a later date. For now my goal is to try and make it as photo real as I can, hence the folds, thickness and rounding etc. Thanks again

Kind Regards

Hi Dr Sassi,

Is there a realistic way to bend objects along an edge? To explain better, I want to fold some packaging but with realistic bends along the edges. I have to do some packaging and I plan to use the same template net of the design for print for a UV texture map as well, that way I can use the same graphic for the printers as I can for the 3d model.

The packaging is an easy enough model, and to fold it I know I can select say a flap for example, and then rotate it from an edge using the axis tool to set the bend point. I can go all around my model this way until it is folded into the correct shape, just as you would in reality. The only problem is, is that the bends are too perfect. When you fold a piece of card in real life, there is slight rounding/bulging along the edge. Is there a way to simulate this in C4D?

Kind Regards,
David

Hi Dr Sassi,

Aah thanks so much for the confirmation, I thought I was being an idiot Yes the cube I put underneath worked a treat

Hello,

Is there a quick way to replace objects in a scene with new objects but have the new ones in exactly the same positions as the originals?

I have a scene with various objects scattered around and I want to replicate it multiple times but with different objects and I want them to always be in the same position. Thanks.

Kind Regards
David

Hello,

Does the dynamic placement tool not work with a floor object? I've been arranging some objects and it has worked as expected, objects not passing through each other but not the floor, they just fall right through it. For now I've just put a simple cube under the floor and that has worked but shouldn't it work with a floor?

Kind Regards
David

Hi Dr Sassi,

Thankyou so much for the reply, your advice is absolute gold! I tried experimenting rendering out with the ProRes 4444 and the options and that gave me exactly what I wanted For the time being and the current workflow this is ideal. This saves me a few extra steps, which when there's a lot of files it all mounts up, and saves quite a bit of time (I'm always expected to get a load of videos done for a particular deadline you see). I will seek out those books you recommended, I have a lot to learn but I know if they're recommended by you I know they will be top notch Thanks again Dr Sassi

Kind Regards

Hi Dr Sassi,

Yes that's correct. I often need to render an object with very simple animation, just the object rotating on its own for example with no background. So I need the background transparent so I can bring the rotating object in to AE where I then add other elements such as backgrounds and text etc. The way I have been doing it is by saving out the extra Alpha channel in the render settings window, then in AE importing that to use for the matte to get the background transparent. I guess I was hoping for a way to render it out from Cinema in one go, similar to how you can export an image in Photoshop as a PNG with transparency for example. I've a lot to learn being a newbie so I may be a bit naive on this yet

Hi Dr Sassi,

When I need to render out an animation of an object that needs a transparent background, I choose the 'Save Alpha Channel' option so I can then import it into After Effects and use it as a matte to give me the transparency I need. My question is, is there a better way to do this? Is it not possible to render out the animation with transparency already there? It would be great to save the step of having to set up the mattes in AE.

Kind Regards
David

You could try turning off uniform scale so it only affects Y in your field parameters, and set it it a minus number.

Hello,

I'm sure this must be easy but I seem to be missing something here. I have made a simple animation of an object that I wish to export as an OBJ sequence so I can bring it into Trapcode Form or Particular. I'm all fine up that point, but in my C4D scene I also animated a camera, I now want to bring that camera into AE but I can't seem to figure it out.

How do I get my CD4 camera into AE?

Kind Regards
David

Hi Dr Sassi,

I haven't used Tao yet but I gave it a look and it looks a great tool to consider for future projects. In the brief time I had to do this project, I couldn't quite see how I could figure out how I could do what I needed so I headed back into C4D. I realised I could do what I wanted with a cloner and then I used a field to move through the clones changing them as I wanted as the field moved through them. I got exactly what I needed this way

Kind Regards
David

Hi Dr Sassi,

I have put in the request Thanks Dr Sassi

Hi Dr Sassi,

Yes I've already seen the 'Show in Finder' option because it appears along with the 'Delete' option but unfortunately for me it does not respond. I've tried it many times but nothing happens. Deleting does work however, but it just takes way too long. Deleting over 300 individual files this way will take hours This is why I have tried to search deeper into the OS to try and find where the original OBJs are. I suspect the problem lies with Adobe because After Effects is extremely slow at various other tasks too.

Kind Regards

Hello

I have a very simple outline shape that I would like to animate moving and changing colour very much like the Blend tool in Illustrator. So I have the shape at one in a particular colour, and say maybe 50 steps to the same shape at the end changing to another colour. I'd like to animate both ends position. Is Trapcode Mir the right tool for this task? Many thanks.

Kind Regards
David

Hi Dr Sassi,

Thankyou for investigating this. It's a bit of a mystery as to where they are held. I've tried searching all through the system including invisible files but I've had no luck. I've also posted in the After Effects discussion site in case anyone there has ideas. I will also take up your suggestion to put it to the Maxon support centre

Kind Regards
David
