Hello Edgard,
Here is the solution:
Near the end of the .ma file you can find this part (just open in texteditor):
connectAttr “Camera_TranslateX.o”“Camera.tx”;
connectAttr “Camera_TranslateY.o”“Camera.ty”;
connectAttr “Camera_TranslateZ.o”“Camera.tz”;
connectAttr “Camera_RotateX.o”“Camera.rx”;
connectAttr “Camera_RotateY.o”“Camera.ry”;
connectAttr “Camera_RotateZ.o”“Camera.rz”;
connectAttr “CameraShape_FocalLength.o”“CameraShape.fl”;
connectAttr “CameraShape_FStop.o”“CameraShape.fs”;
connectAttr “CameraShape_FocusDistance.o”“CameraShape.fd”;
connectAttr “CameraShape_ShutterAngle.o”“CameraShape.sa”;
Enter a space between the 2 strings and then save the file again. It should look like this then:
connectAttr “Camera_TranslateX.o” “Camera.tx”;
connectAttr “Camera_TranslateY.o” “Camera.ty”;
connectAttr “Camera_TranslateZ.o” “Camera.tz”;
connectAttr “Camera_RotateX.o” “Camera.rx”;
connectAttr “Camera_RotateY.o” “Camera.ry”;
connectAttr “Camera_RotateZ.o” “Camera.rz”;
connectAttr “CameraShape_FocalLength.o” “CameraShape.fl”;
connectAttr “CameraShape_FStop.o” “CameraShape.fs”;
connectAttr “CameraShape_FocusDistance.o” “CameraShape.fd”;
connectAttr “CameraShape_ShutterAngle.o” “CameraShape.sa”;
The importer should be able to read the file now as expected.
I have a version of the plugin without this problem but it only works up to version 10.5
Cheers
Diego
