@Michael McAfee Please attach the scene file and videos you have

Yes, archviz is big market and getting the real time rendering tech on both Win and Mac is quite nice

Happy to say I prefer forum discussion much better than anything else. At very least bashing is delegated to very end of the topic 😄

Here is a curl spline setup, quite interesting! Curl_spline.c4d

You can generate various geometry types (including an instance if needed) using hair itself using generate tab. Check the attached simple example head_hair.c4d

Highly doubt that will happen Same here, not my industry and I must have been living under the rock since I did not hear about them before : )

@Jakobwagner There is a known issue where that node is not working correctly with modifiers. The reason is that it is meant to be used in object generation, not modification. If you use a spline capsule (which is a generator), then it works properly, see attached scene test add point to spline_0001.c4d

I took just a part of the mesh due to scene being so heavy and used volume as emission type. This helped a lot in resolving the "streaks'. I would still go with proxies for this

@Julien Scene is very heavy, can you possibly reduce it and reupload? I can barely navigate and see the issue, however, it looks like you are not happy with emission type? Either that or use a proxy object for emission

Volume vectors Tornado fun: ) Tornado_vectors.c4d

@bez The setup used in video can be changed to fake volumes, it could also possibly work with some volume distribution magic. Use a spline derived from object (use edge to line node) and see if that leads you results which work for you. Other than that, it is an interesting challenge 🙂

@bez The setup you have is causing cyclical dependency which is undesired and will lead to issues in animation/rendering. There is a differential spline growth tutorial here It looks like the capsule you purchased is based on that tutorial? Anyway, when you say "volume" you basically want growth contained within closed mesh, correct?

Ah, I understand now. Still, nodes could be easier and way faster solution (than Xpresso or Python) for what you need. Can you, just for sake providing insight into your work, and I am pretty sure there are quite a few people interested in particular work you do, provide some requirements? Even generic ones would work. Nodes can really provide you with fully parametric, customizable, user oriented rigs. If anything, we can identify weak points for particular task and improve the nodes themselves 🙂

Not into python so the question is would nodes work for you? We would need to have an example of what foldable door you are after, nodes are very good for this type of work.

I believe that you will be quite pleased then. Check around june 6 for info that will most likely pop up with some details.

There seems to be more members but there is less posting. Seems most of the questions are already answered 🙂

Here is a version where goal is kept and both sides can be transformed, rotation happens in direction where one would expect (use the goal null). Not sure if that is what you are after, and if so, you will need to elaborate a bit 🙂 overextended mechanical joint_0003.c4d

@Exitaph Is this what you need? overextended mechanical joint_0001.c4d

Hi there! I believe this can be setup without IK, rather with some nulls and proper hierarchy. Would be easier if you can share the scene file?

Not particles or pyro, but still fun - field and volume based cheese 🙂 167_OpenVDB_cheese(MG).c4d

Here is a nodes mesh version, should be math correct rhombohedral.c4d

Checked this topic? https://www.core4d.com/ipb/forums/topic/117430-boat-wake-in-c4d/#comment-752951 Maybe there are still valid plugins available. Do you really need to use bitmap at all? I presume this is because you need to have correct wake shape (kelvin wake). In such case bitmap will just be showing static deformation. Maybe you are better off with something animated, yet not physically correct (do a search in file pits, there is boat wake with fields). If you need correct, simulated kelvin wakes you are looking into custom solution, doable by nodes or python. This is quite a task since you need to include bow an stern wakes, take boat size into account, time and decay, that is a lot of math...

Faking it can be done with tutorial above using multitude of tools you have at disposal. I think it would be quite interesting to have a physically correct rig for this 🙂

The Classic - Carpet roll! 120_Carpet_Roll(MG+XP).c4d

Lava lamp with scene file, attachment is missing in one of the posts above : ) 18_Lava_Lamp.c4d
