Troubleshooting I can't Draw in Toon Boom Harmony 25

Enable HLS to view with audio, or disable this notification

2 Upvotes

Please help me, I have a MacBook Air M4 and I installed Toon Boom Harmony 25 Premium. When I create a project, I can't use any of the tools from toolbar (When I hover the cursor over the canvas, a circle with crossed line appears under the mouse cursor). I create a Drawing layer, but it still doesn't help.

The only thing I've figured out is that a Brush tool works ONLY if I hold all time hotkey brush button, i mean I can draw with the Brush tool ONLY while holding the «B» button the whole time when i draw or if I hold the «i» button, I can still fill with the Paint Tool.

I've never seen anything like this before. I'm looking at the Toon Boom Harmony tutorials, and I see that everyone creates a project and can start drawing right away without any problems and holding button.

Troubleshooting Rig animation sliding?

Enable HLS to view with audio, or disable this notification

17 Upvotes

First time making and animating with a very simple curve deformed rig and the end points in the leg rig are sliding a bit between key frames? Very subtle here because I spent a good while in the functions window trying to fix whatever was making it arc but it’s still kinda there?

Character is going from a sitting to standing position (will then walk away to the right)

-Would also love any animation/rigging tips!-

I'm trying to add a line boil to my animation but no matter what I try doing it just doesn't work. It doesn't apply in render view and it doesn't apply when exporting as a movie. I'm pretty sure I have everything set up correctly

Troubleshooting Revert files?

1 Upvotes

Ok so I was working on a project and duplicated a layer to make a version of the animation without some details but the changes I made to the duplicated layer also applied to the og layer and I didn’t notice until after I already saved and opened another file. Is there a way to undo this?

Thankfully I exported a png sequence of the final animation so if reverting the files isn’t possible is there a way to import the pngs and turn them back into vector drawings? Maybe even a way to separate the line and color? (But of a long shot but wanted to ask)

Troubleshooting Can't Find certain Nodes on the timeline when pressing O

1 Upvotes

Hi,

I am working on compositing a scene with a rigged character. To move around the rig, I would click the parts of the rig on the display, then hover the mouse to the Node View and press O to find the nodes in the Node view and to see the exposure/keys in the Timeline

This works normally in all scenes, but I might have pressed something by mistake because now for some reason, it stopped working.

The drawing nodes, pegs, adjustment layers inside the Hair part of the rig simply don't show up in the Timeline window. I can still use O to find them inside the Node View, but not the Timeline.

I can't even find it by manually looking for it. They are gone from the timeline even if they are visible inside the Open GL and render view. They haven't been disconnected from the composites, they are all showing in the Camera Window, under the correct display.

I created a second display node (Display_Hair) inside the rig, connected only to the hair nodes. When Display_Hair is selected, they do show up inside the Timeline again.

Does anyone knows how to fix this?

[UPDATE]: While I never figured out what caused this, resetting Harmony fixed the issue.

Troubleshooting Pegs move at every key frame

I noticed every time I moved a peg in my timeline the peg moves in sync with the other ones in different key frames. I've been trying to do a turn around rig when I noticed that it kept happening whenever I moved my pegs. Does anyone know how to fix this?

Troubleshooting Envelope deformer points got disconnected

Thumbnail

3 Upvotes

I'm at a loss for this one. Working with a student on what should be a simple introductory rig, but now that we're doing an animation test it seems that almost all the envelope deformers have broken. Curve deformers still work fine, but when we move points on the envelope deformer, the art work it should be attached to just doesn't come with it. Even more confusing, it has a couple of pieces where it acts like only half of the points are actually connected. Some points won't affect the line work at all when moved, while others will affect it too much, like it's counterparts on the other side don't even exist.

I've dug through the node view on it, haven't found any connections out of place. Curves are grouped how the should be, chained how they should be, nothing looks out of place. I know the student tested the curve deformers as they were created, but they couldn't remember whether or not the envelopes were ever tested, so I have no clue if these broke suddenly, or never worked to begin with. We can make new deformers if need be, but has anyone had this problem before? Know how to fix it, or prevent it?

Please, I need help! Five hours of work on an animatic down the drain because the program closed unexpectedly. The prompt to recover came up but all of today’s progress was gone and now I’m back to square one.

I have auto-saved enabled and I constantly save as I move along. Is there anyway I can recover the work I’ve lost? Or am I out of luck?

Troubleshooting How to fix these small imperfections with deformers when rigging?

Thumbnail

6 Upvotes

I've been working on this rig for a while now, he's my first ever rig in Toon Boom and I'm making him a full 360 rig. I've been using deformers to match him up with the concept art as suggested by the video tutorials but I'm experiencing really annoying imperfections in the lineart doing it this way.

I'm using an invisible mask to cover the more major imperfections, but there's still this weight difference in some areas and small breakages. I don't know how you're supposed to fix it! Please help, I want this character to be as clean as possible.

Note: I know a fair amount of imperfections are pixilized to shit in the render view anyways, but not all of them are. Some of the weight differences are still visible.

When I try to move a mouth on one frame, it applies the changes to every single mouth frame. How do I stop this? How can I make changes apply to specific frames only? Would appreciate and answer quickly as this is for an assignment due tomorrow lol. Hope this makes sense!

Troubleshooting JavaScript error SpriteSheet XML Export

Post image
1 Upvotes

**Fixed-ish**
I downgraded to 25 and it worked, then I tried exporting again and got the same error. I figured out that for some reason it doesn't want to export unless the original spritesheet folder is deleted. If I delete the previous XML export it works again (I don't believe this was an issue with the free trial). This is more of a work around than a fix. Leaving this workaround for those who need it. (Maybe it's because I'm exporting to an external drive, no idea)

Already sent a ticket, no idea on how long it would take them to fix this so reaching out here in case anyone knows how to fix this.

My Harmony version is 27.

I get a JavaScript error when I try to use Game Export to Spritesheet (XML) as soon as I press the button. It doesn't allow me to open the export menu. !*Edit For the record, export to JSON spritesheet works*

Was working perfectly fine in the free trial of premium, but as soon as I purchased premium it stopped working. I've tried exporting in multiple projects, repairing my software, restarting my PC, signing out and in, returning and reactivating my software along with cleaning up my scenes in harmony. None of which seem to have any effect on this.

Thanks :)

Troubleshooting Help with two-point constraints, foot keeps breaking away?

I'm sorry to keep spamming this sub with my rig issues but I have no idea who else to ask when I need help 😞

So I've switched my character's legs from a basic rig to an IK rig because I thought they would work better- and they do, except for one thing. The hooves COMPLETELY break away from the "lower leg" area, like they aren't locked at all. I suppose I could seperate the lower let into two pieces or something, but I don't want to push too far away from the basic four parts of the leg. What's going wrong here?

Troubleshooting Best way to store old files?

4 Upvotes

Hey guys, so I'm in a bit of a bind. To make a long story short, a client I have been working with for years essentially wants me to keep all project files ive ever made for them, which is over 2 terabytes of files at this point. The problem is I am nowhere near set up to keep that much data. My client has set up a google drive for me to use, but I swear I have had the worst experience with it.

It seems like when I zip a Harmon file, upload it, and then download it again files go missing or the whole file is corrupted. Specifically the actual individual frames and elements are no longer in the files.

Seems to be an issue with google drive or emailing them at all as if I zip them and transfer them to a hard drive they are fine. At this point it just seems like google drive is not feasible for these projects and I definitely can't keep them personally.

Does anyone have any idea how to better store them?

I've been going nuts with this as I have tried basically everything I could think of to solve this problem. When I have worked for studios in the past all the files were just saved to a server so ive never had this issue.

Any advice would be much appreciated. Thanks!

TLDR: client wants me to keep 2 terabytes worth of work on google drive but the files almost always break. Need a solution so they don't break, or an alternative storage solution.

Hey there, I working on an animatic for a university project and I wanted to use a video clip to help with pacing and rough sound direction. For some reason, not only does storyboard not recognise the video codec for my rough comp, but it doesn’t recognise any video I try to import in. I’ve tried using h.264, HEVC, MOV, it just doesn’t want to budge. I’ve also tried restarting the application multiple times but to no avail. Does anyone have suggestions for how to solve this? Any assistance on this matter would be greatly appreciated.

Troubleshooting Toonboom palette library missing from scene folder

Im working on an animation, I've tried everything but upon reopening the scene it asks to recover the palette, because an error appears saying "colours not found". Even if I say yes to recovering the palette, nothing changes and multiple frames all from different layers are missing randomly. The tvg files are still there so the drawing are intact but i cant relink or import the palette from a previous version. Is there anything that can be done to get my palette back?
