  Rope scale difference between start and end
Posted by: Hakazaba - 14-03-2021, 07:03 AM - Forum: Obi Rope - Replies (3)

Would it be possible to make a rope which is small in scale at one end and thick at another?

Alternatively, can i have a rope drive a chain of rigged joints on a character mesh?

Pregunta OBI Skinned Cloth and OBI Proxy
Posted by: dequid - 13-03-2021, 04:18 PM - Forum: Obi Cloth - Replies (3)

Hey there,


i am trying to reproduce the CharacterCloth scene with my own character.


I have have a Skinned Mesh Character driven by an Animator (imported FBX).


I have a high resolution coat (green, ~30K vertices) and a low res one (gray, ~6K vertices). Both are skinned and weight painted to the bones of the character.


I successfully made the low res coat an OBI SkinnedCloth, made a blueprint, deleted the upper vertices since i want only the lower part to simulate and painted the skin radius for the lower part. I added capsule colliders to the leg bones. That works like a charm so far.


Now i want to transfer this simulation to the high res coat like in the CharacterCloth scene.


So i gave the high res coat also a OBI SkinnedCloth, chose the blueprint i made for the low res coat and added an Obi Cloth Proxy with the OBI SkinnedCloth Renderer and a triangle skin map like in the Proxy tutorial in youtube.


But nothing happens with the high res coat and i get the following error:

Code:
ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

System.ThrowHelper.ThrowArgumentOutOfRangeException (System.ExceptionArgument argument, System.ExceptionResource resource) (at <9577ac7a62ef43179789031239ba8798>:0)

What am i doing wrong?

  Fluid isn't visible
Posted by: Cdelim - 13-03-2021, 03:56 PM - Forum: Obi Fluid - Replies (1)

Hi,
My project renderer setting is Universal Render Pipeline. The fluid isn't visible in the Game tab but it becomes visible in two cases. First, during runtime when I switch to the scene tab it becomes visible in both. Secondly, it becomes visible when interact other fluids. Also, I have 
"Metal: Shader[Obi/URP/Fluid/FluidShading]: Incompatible texture type [MTLTextureType2D] of texture bound at index 0, expected [MTLTextureTypeCube]" warning. http://obi.virtualmethodstudio.com/forum...-2464.html I tried this solution but didn't work for me. 

Unity version: 2019.4.13f

  ObiCurve component missing
Posted by: alehrecke - 12-03-2021, 03:28 PM - Forum: Obi Rope - Replies (1)

Hello,

I am new to Obi and have started playing around with generating obi ropes through scripting and have been looking through the example scripts. I am particularly interested in the Runtime Rope Generator script. However, when I try to load it the ObiCurve component is missing from the folder hierarchy. The only asset that has the name ObiCurve in the latest download is the ObiCurve icon and there is no cs file that it could be linked to.

Could this be a problem with the latest build (Obi 6)? or am I missing something?

  Obi Rope Pin constraint
Posted by: giuseppe.b - 12-03-2021, 10:57 AM - Forum: Obi Rope - Replies (1)

Good morning,
I am using the latest version of Obi and I am having problems to attach object to an Obi Rope. The effect that I want to obtain is that the object hangs from the rope without falling on the floor. I have read the user manual so I used an Obi Particle Attachment with target on the object that I want to link to the Rope and I used the dynamic type.
If I grab the object, the rope will follow it, and I am satisfied with this effect. But when the object is released I'd like the rope to keep the object "suspended in the air", like a true rope would do. Even if I have changed the stretching scale and stretch compliance the rope is still too stretchy and will stretch until the object falls on the floor.  
I have also tried to change some parameters in the Obi Solver, such as the iterations of the distance constraint and I also changed the number of substeps in the Obi Fixed Updater in order to add particles to my rope and make it more stiff, but nothing seems to work.
What should I do to keep the length of my rope fixed and make it stiffer as it's necessary to hold the objects without stretching too much? 

Thank you for your support,
Giuseppe.

  Only render ropes
Posted by: Jesse - 11-03-2021, 09:30 AM - Forum: Obi Rope - Replies (11)

Hi Jose,

I'm experimenting with ropes that simulate on the server and render on the client. Is it possible to disable simulation and only enable rendering?

See image here. 
Disabling the RendererFeature returns the scene to normal (without fluid rendering obviously)
