I've created a static object, a rigid object, and a cloth object to all interact. problem is with the rigid object the cloth object is returning an error. so 2 questions.

1. when a node turns red how do you find out what the specific error is?
2. what is specificly causing this problem?

Hi queglay

If you want to see what the error message is - MMB on the center of the node.

There are a couple of things wrong with your file;

1.) Both your spheres need to be polygons. Right now sphere_object2 is a primitive That is what the red flag error message is telling you. You should also delete the first DOP Import SOP in /obj/sphere_object2/

2.) Your RBD sphere is falling through the grid. The best way to fix this is to make your grid a Terrain Object. This is the most efficient way to make a ground object. Or you can also change your Static Object DOP -> Collision tab -> Volume tab -> Mode parameter -> to Implicit Plane. This helps the DOPs sim define it's collision geometry.
