Good morning: We’ve just need to create a “functional” measure tape and wanted to do it the classic way, made of a plane with a non-linear bend deformer, in order for it to curve on itself like a snail. The case is that GLTF doesn’t export deformers, so we need to llok for another way. We tried wi…

Hi there @bghgary : I’m translating your comments to the resident 3D artist guy in the company, and will let you know. Thanks for your time.

Hi, I’m the 3D guy LOL Having watched the youtube video about morph targets, I confirm they are the same as blendshapes in MAYA. But with one exception there. While glTF morph targets just support going from point A to B, so they blend between source mesh to destination, MAYA’s blendshapes CAN ble…

I don’t know much about this. Maybe @PatrickRyan has seen this before?

@joie , sorry for the delay in my response. As far as I know, glTF does not support one parameter morphing between multiple shape states. The way I would normally pass from one shape through another to the end shape is by cross fading the influences like this example. Here I’ve started with a cube, …

I wonder if this should be an exporter issue. Maybe it’s possible to automatically separate these morph targets on export. cc @Guillaume_Pelletier

Hello, The exporter is suppose to deal with multiple target for a weight. the final weight associated with the target is calculated using weight * envelope where envelope is a global scale factor that is applied to all of the weight values in the deformer (Maya API). So at this point we may end…

Hi there, Thank you for the explanation. I saw something like that in the video about infinite morph targets (which looks promising until you realize you can’t do that with the exporter, that guy does it via coding). Your example is perfect for something very simple, but in our case, we would need…

@joie , thank you for the explanation of what you are trying to achieve, this context helps us understand the real issue you face. The limiting factor in all of this is that you are trying to bake all of the animation into the glTF format. If that is the goal, then I am expecting that you want to be …

Also, I think @bghgary and @Guillaume_Pelletier would be interested in possibly looking at the file that wouldn’t export. I don’t know if there is a limit to the number of bones in a skeletal hierarchy in glTF but the fact that it sits for hours and doesn’t export tells me there may be an issue in t…

Hi there @PatrickRyan I’d like to thank you for the so in depth explanation. We want to test if we can make the displacement map trick first, since your solution is quite involving. Here you can download the test scene with the geometry and the IK Spline joint hierarchy that moves it. It would be …

Hi there @Guillaume_Pelletier
Do you have any update on the issue?
Thanks!
