C3d file, Invisible markers in anybody


I input a c3d file in anybody and load it, but I can not see the markers in the model view. I put my language as below:
AnyInputC3D c3d = {
FileName = “jumping.c3d”;
MarkerRGB = {1, 0, 0};
I try another c3d file and I can onle see one marker.
I also run the two c3d files in Mokka and I can see there are many markers in both of them. I run the play button, the markers also work well. So I am wondering what is the problem?
I use AMMRV1.0.
Thanks for any help!
