    Dynamic IK advice please.

    For anyone who is interested, I've attached a scene file that seems to fix the problem I had with the joint goal slipping away from from the control null, and the problem of how to control a joint chain from either end using Joints and a Spline IK tag. Selecting the Spline IK tag, then in the Attributes Manager, setting Type to "Equal" rather than "Fit" seems to keep the final joint in the chain attached to it's target. I used Clamp constraints to prevent the control nulls from travelling past a given distance for one another, to avoid the stretching you get with dynamic spines. Hit play on the timeline, then move the control nulls around to see the effect. Hope this helps someone with a similar problem in the future. Spine IK.zip
  2. Now that's some dedication! Maybe you'll find an easier solution in the future :)

    Dynamic IK advice please.

    @digivisions, Thanks for the reply. I was beginning to suspect this. Tried a few workarounds like adding a 2nd goal, and extra PSR constraints, but nothing has worked so far. Thanks again.

    Anyone have any ideas on this?

    Importing STEP files

    Maybe try going back to MOI, or use something like freeCAD to get a workable file.
  6. You should b able to export your .c4d scene to .obj , .fbx or alembic without without any problems. Whether your choice of CAD software can import /export that file type is another matter. I'd post on some CAD forums for additional feedback.
  7. If you're able to slice it in some CAD software and export that animation as an alembic (.abc) or .FBX, (or search for an exporter that can do this) you could then import that file into C4D, and use Octane as you normally would. I don't have any other ideas unfortunately.

    Importing STEP files

    Best to check supported features at the MAXON site, or contact their support team. But if that is the case, providing project is not under an NDA you could ask one the cafe members if they can import the .STEP it and export it as an .OBJ, .FBX or similar.
  9. Ah I see, niether Octane or the Fracture object would suit you purpose then. It might be worth looking into some free CAD software such as FreeCAD, I remember seeing the same slice functionality you mentioned in some CAD software a few years back, I don't remeber the name of it though. You could post your vimeo link on a few CAD forums to get some additional suggestions.
  10. I've made a simple joint chain with an IK tag that I want to be able to control at either end with control nulls. It works fine, until I make the IK tag dynamic, then the end joint falls away from it's Joint Goal, even though I have enabled "Keep Goal" and "Contstrain Goal". I'm trying to copy the same functionality you get with spline dynamics, where a spline can attached to an object at either end, and as you move the each controller the spline with dynamics moves accordingly, but the ends vertices stay attached to the controllers. Is the problem a priority order issue? Or is the joint IK just not meant to work in this fashion? The scene file is attached. Try enabling/disabling the Dynamics box and you see the end joint slip away from the Goal Null. Dynamic Joint Chain.c4d

    Anyone using Prorender?

    I don't think their are any free 3rd party renderers for C4D outside ProRender. Cycles4D is probably the cheapest, but as others have said, Redshift seems to be the most popular at the moment.
  12. The only other ways I can think of would be to put the mesh in a Mograph Fracture object, and use the Mograph Effectors (R19)/Fields(R20) with a fall-off to scale the individual parts down. The problem with that is you'd need to set the axis point to one end of the meshes, and as you've mentioned, the scene has lots of moving parts, so might be long process. It wouldn't be the effect as a boolean, but if the transition is quick, and there're lots of parts, it would look quite similar.
  13. I don't use VRAY so can't be sure, but i've seen previously on their website that they have a VRAY Workstation monthly rental, try contacting them and ask for further details. It might suit you better if you can just rent it for a month to complete the job and then just cancel the subscription if that's possible.

    Importing STEP files

    I received some .STEP files recently and they seem to open fine so maybe ask your provider to give you .STEP rather than .STP Although the documentation does state that both .STEP and .STP are now supported. One other thing to check is that you are using the File/Merge command to bring in the .STEP file, not the File/Open method.

    FBX export is broken?

    @chadiabo It seems to work if you take your camera and the animated Nulls out of the main parent Nulll object.
