A wonderful lesson can I ask you how to implement the work of capturing a curve in APEX, like there are a lot of bones around the mouth, but in order not to control each bone from the sets, I make a nurbs curve and use RIGVOP to control the entire curve around the mouth, but I have only a few control points how to transfer control to APEX I do not know or tried to do something similar with wiredeform, but I also don't know how to make friends with APEX

What are the reasons you continue with Unity over Godot or Unreal Engine?

@brundlethwaite 2 ай бұрын

Ideally this will be running on the Frimble engine but I do not know If it will ever get that far. This is a prototype so it may never be released other considerations are. - My interest here is animation and Rigging not programming or releasing a game Unity is the easiest to deal with at the moment. - Unity is easy to use, I know it and it is the most fun to work with at the moment. - As this is a prototype Unity is free. - Unreal would be far more expensive than Unity (even if they had implemented that stupid pricing scheme). - If I release the game It would be for consoles Godot has no support and would end up being more expensive than Unity. - Godot does not have Houdini Engine support. - Flax does not support graphics tablets. - Flax does not have native Houdini engine support. - Cryengine does not have proper UI and requires defunct commercial software. - Cryengine does not have native Houdini engine support. - Programming in Unreal is horrible and is it weakest area. - For game logic I do not want to use blueprints as they and not efficient and have worse performance that C++. - I do not want to use C++ I would prefer to work with C, Odin or C#. - Animation is Unreal's weakest area Unity is far easier to work with here. - Animation import and Export it Unreal's weakest area. - Unreal's coordinate... - Unreal's syntax..... ... ... This is a little brief, I start to give some more reasons but I do not want this to become a long list and I do not have the time to go into even the basic reasons as each of them require context and explanation to make sense.

"no way! Unreals animation is weaker than unity’s?" What relevance does this have? I did not make a feature comparison? This is not a reason or advice on choosing. And it is not relevant to anybody by me, for this specific project. " I spent sometime with Unity and hated C++ until I started using it and now I look at c# as a jumbled mess lol." What relevance does this have? This is not a programming language comparison? These are really bullet points as they applies to this specific project. I am not going to spend days (or for this topic months and years) of my life trying to explain the specifics. You asked me why I am working with Unity you did not ask me why someone else should.

@brundlethwaite Ай бұрын

"My question initially was to see whats stopping you from converting to UE." You did not state that. You said "What are the reasons you continue with Unity over Godot or Unreal Engine?" which is a completely different question. I am not converting from anything I currently have projects in Unreal, Unigen, Flax, Godot, Cocos2D and Stride and Cryengine. Not all of the projects are fully active but I none are discarded. So if you had asked the first me about converting I would have said that I am using Unreal different projects instead of why I am using Unity in this one. You also chose to ignore the final statement where I said that each of the points was highly contextual. As well as the first statement.

Anny way to do this in a way that the Ik chains don`t go over set limits ?

@brundlethwaite 3 ай бұрын

This is limiting the controls not the joints. There is no built in limit to control IK chains (you can make one manually in vex or VOPS). You can force IK chins them to return to an original pose using rest transforms. Using rest transforms will stop you joints from going beyond a straight line as they will always return to the default. I do not think this applies to the IKchains node. As that uses the 2 bone Ik VOP. But if you use the IK Solver VOP you have the rest angles mode.

What was the goal? To move the character with a control stick relative to the direction you're currently facing? Like you push up on the stick and he walks forward even if you're looking back at the camera?

@brundlethwaite 3 ай бұрын

The character needs to move relative to the camera. So the controller is essentially moving the character in screen space. But the character is not being driven by the controller but is using root motion and is purely driven by the animation. Essentially this is a animation prototype 1st and if I get a good results from that I may turn it into controller prototype. There is also some tool creation that is incidental to the prototypes/

There are a series of videos for the prototype for a bone based rigging system on my Patreon. I am working on a full course but editing and recording takes a long time and I have had a lot of interruptions so it is taking a lot longer than I want. Personally I dislike blendshapes as bone based rigs give much better interpolation so will be a bone-based course. Unfortunately it will have to be a paid course. I cannot justify placing it on KZfaq for free as it I too much work to do for no compensation when I have a very limited income.

great stuff! why are yoy changeging the default transform option to "into this node" in object merge node? I never fully understood that?

@brundlethwaite 4 ай бұрын

That is really just habit and does not have that much effect here. The "Into this node" option allows you to use the obj/ level transforms into the sop level. If you have an object containing a mesh and you transform it at the object level and then try to bring it into a separate sop you will not have the obj level transforms affecting the geometry so you will only get the local position not the global position.

What solvers are you using that are flipping? I make my transforms manually so that I know they are consistent. So I avoid flipping by always having matrices that do not flip (with the exception of quaternion rotation based spines). This is something that is very difficult to explain without knowing what your scene is doing. But I will try to make a video explaining my approach a cannot give an ETA though.

Hi, great tutorial! Could find it in search since it doesn't mention Houdini, but someone just recommended. I am still trying to figure out two key things in APEX. 1 - How to make a simple skeleton blend like in KineFX, for animators? Can we actually have a slider in parameters, or it could be only connected to a control, like the IK/FK switch on the chicken in 3D space? 2 - How can we bring an existing animation to APEX? We have motion capture, perfectly retargeted to a skeleton (with KineFX). There is a demo file from Esther of KineFX/APEX that is nice, but it's actually retargeting to the controls, and there are some jumps and flips etc. If we have the animation on the exact same skeleton, can we bring it to APEX (I think devs mentioned some rig inversion in a chat, but couldn't find any info about it), and animate with a rig on top of mocap? Do you have any idea on these? Thanks!

@brundlethwaite 5 ай бұрын

These are the same places where I am having the most frustration. I will get to blends. But form what I have got working sliders are not great. At the moment it is easiest to work with on screen controls (which is not something that I like as I favor slider interfaces). Unfortunately there is nothing listed in the documentation but this is something that I am looking for solutions to. As for mocap I would personally stick with KineFX as it so flexible and unless you have extreme slowdown you will be loosing a ton of flexibility. The APEX setup gives you a lot more performance but the mocap approach is far more limited and is not dynamic. I have done some testing but am not yet satisfied with anything. So I am working on these and still have plenty of things to try but there are no real options that I am satisfied with yet.

From my limited understanding, it's basically a visual representation of how the apex graph is stored as geometry data. Each node in the APEX graph is represented as a point with attributes. I too found it rather bizarre at first but I think SideFX simply chose to store graph the data as geometry and the visualization is more of a side effect than a purpose. There's probably a better reasoning for storing the data as geometry instead of something like a text document.

It is mostly a motion capture format and was not supposed to be updated. Autodesk have updated it a little but that is minimal. The materials have never been updated as far as I know and materials now are very different from 1996.

Are you exporting from obj level? please advise, and thank you for these videos they are very helpful!

@brundlethwaite 8 ай бұрын

The export is in this video kzfaq.info/get/bejne/hNtjd7R81d2YZqs.html. I have go the export working with both Unreal and Unity but I only test unity. The final packaging of the export is here kzfaq.info/get/bejne/o8ude8t2nJfbZ3U.html. This should not really help much though as it is primarily packaging and not functionality. FBX is not great for materials and getting the correct attributes exported can be frustrating. For example if the groups and names are not just right pose space transforms will break. If you have more than on mesh that you are exporting with the model each mesh will need to have the correct matching values for the name of the mesh and the materials and there should only be one material per mesh. Generally I do not really use the material export in FBX as I do not need it and I am going to make the the materials in the game engine but I have had to deal with it in the past. I will try and do a more dedicated set of videos on export and packaging but that is time dependent.
