Reactor Help!

#1

Ok hello all,

I’m quite new to reactor and I have a few questions to ask all of you guys to help me for my school final year project! Ok here goes (done in a group so Im using we):

We have a character modelled and we rigged the model using Character Studio 4 Biped. So we did a walking of the character using footsteps and such. Now we have a trenchcoat that is supposedly worn by the character.

I used Reactor to select rigid bodies and cloth collections. So the ground and body goes into rigid bodies and the trenchcoat into cloth collections. After that I used Mesh Select for the cloth to select the vertices and then used attachToRB, and of course attached it to the body.

Ok my walking begins at frame 60. So from 0 to 60 all works well. Cloth falls down nicely follow the body shape etc but when the character starts to walk, the cloth doesnt follow. I am not sure why. I have tried all I can but it just doesnt follow. I’m sure I did the setups right, Mesh Select, attachToRB etc

Current Test Setup:

Models - Character Body, Trenchcoat, Ground

Details:
Character Body (Rigid Body):

  • Rigged with Biped
  • Reactor properties mass 0.0kg (default settings in other words)
  • Animated using Footsteps, manual etc
  • Problem, cloth doesnt follow when character starts to walk
  • A non convex object (using reactor’s test convexity), concave

Ground:

  • Box
  • Reactor properties mass 0.0kg (default settings in other words)
  • Convex

Trenchcoat:

  • Box modelling and some of other cloths Plane
  • Added to cloth collection
  • Used reactorCloth, Mesh Select, reactorAttachToRB as modifiers
  • Reactor mass properties 2.0kg, reactorCloth properties mass 2.0kg, Avoid Intersections, Vertex Selection: Non selected are unyielding
  • Concave
  • Problem doesnt follow body

Ok so those are all the details. I hope I am not too wordy. I have not come across any tutorials relating Reactor and Biped etc. I just need one solution: Make the cloth follow the body using Reactor.

Do reply me asap cos our project deadline is a few days away and we just need to solve this cloth thing to get us done!

Regards,

Can you upload/email the max file?

Tried the check box effect only RB or somthing its been a while since I did my Physics Proj but I remeber having a similiar sort of problem.

I think its just like a check box or somthing thats missing.

Then again I could be totally wrong :slight_smile:

I’m not at my 3dsm now so I may be off but a couple of things to check.

a) make sure your character is a MESH and not a POLY.
b) character needs to be added to ‘deformable mesh’ i think.

rigid body will not move with your biped, so even though it appears that the body moves away, as far as reactor is concerned it is till there…

c) IF you character is still a poly, then you will have to convert to Mesh prior to adding it to deformable mesh, as polys don’t work.

I think this is right, but let us know… cheers.

They work very well with poly … I just completed a project on that !
