When the "Skeleton Sampling" is enabling when generating particles from the softbody blueprint editor, the generated particles since to move along with the bones. My questions are:

1. What's the constraint taking place here? Distance? Pin? Shape matching?

2. Can I disable it? In other words, I'd like the particles to be generated at the positions of the bones, but I'd like them to work just like volume particles and surface particles: bound to other particles by shape matching constraints, but not bound to the bone.

It seems that Obi renderers randomly stop working when the "Pause" button is pressed in Unity editor.



Please take a look at this video. The fluid just disappears and reappears randomly. Sometimes it works sometimes it doesn't.

   

ObiFluid (7.0 in this case) prints a lot of shader warning to the console upon entering the play mode.

I suppose these can be safely ignored. However it's very inconvenient to develop/debug anything when your console is spammed like this.

Typicial warning is:

Shader warning in 'ParticleGrid(Clone)': signed/unsigned mismatch, unsigned assumed at kernel BuildFluidDispatch at ParticleGrid.compute(359) (on d3d11)

One possible solution seems to be adding this in MathUtils.cginc:

#pragma warning (disable : 3203)
#pragma warning (disable : 3206)

But I don't think it's necessarily a good idea, and even if it is I'd hope to get it officially fixed, otherwise I'll have to manually put these lines every time I upgrade Obi version.

Is it possible to just assign a mesh to ObitEmitter and make it emit one particle per vertex? I don't want to voxelize the mesh or anything. Just emitting from each vertex.

Hi, i plan to simulate gluing cloth to a softbody, and glued cloth also can be pulling off.I try to use obi attachment doing this,but it require rigidbody for dynamic attachment, how can i do this without applying rigidbody to obi softbody?Any help would be much appreciated. 

ObiParticleRenderer Obi Solver and Obi Emitter look like grains, not liquid.
Using a blueprint that looks like a liquid and uses "FluidViscosity" And "FaucetAndBucket" in the Sample did not solve this problem.


This Obi Fluid Renderer description may be relevant.
http://obi.virtualmethodstudio.com/manua...ering.html

However, specifying the Emitters placed in the scene in the Particle Renderers of the Obi Fluid Renderer did not change the appearance.


Also, all the Obi Fluid Renderer values for "FaucetAndBucket" in the sample "FluidViscosity" look default.

The API document of ObiSoftbody has this description:

Quote:override void Obi.ObiSoftbody.UpdateParticleProperties()
Recalculates shape matching rest state.
Recalculates the shape used as reference for transform position/orientation when there are no fixed particles, as well as the rest shape matching state. Should be called manually when changing the amount of fixed particles and/ or active particles.

I'd like to disable ObiSoftbodySkinner at runtime and make the mesh deformation controlled by SkinnedMeshRenderer again, and reenable it at some condition.

The first time disabling it works. However, if I enable ObiSoftbodySkinner again after disabling it, I get this error:

The QuickstartGuide_softbody.pdf contains the following information.

Quote:1.- Include the Obi package in your project. Right click in the project window, "Import
Package" → "Custom Package", then select ObiSoftbody.unitypackage.

ObiSoftbodySkinner has a "Paint Influence" feature. It works okay for simple meshes, but for more complex meshes it's quite hard to paint the influence precisely in Unity's scene view.

I think instead of painstakingly paint it in Unity, it'd be much much easier for me to paint it as a texture (or vertex color) in a proper 3D DCC then import it to ObiSoftbodySKinner. Especially that Obi 7.0 has a "SkinMap" structure that seems to be for this purpose. But I don't know how. Is it possible?
