I have been playing with some model bridges using the following code line, ADDCAT OBJECT_0_SCALE, 8The line of code definately sets the model on solid ground and stops the model from floating or disappearing into the ground, however, the model displays a semi transparency effect which is annoying.I have tried ADDOBJ OBJECT_0_SCALE, 8 and that doesn't work. The model will float or disappear into the DEMAnyone have an answer to sticking a model to the ground in custom DEM without it displaying this translucent texture problem?http://members.rogers.com/jkanold/jimlogo.gifhttp://members.rogers.com/jkanold/flyurl.gif

Jim,It is not strange that you get those transparant effects. The command ADDCAT is similar to the SCASM LayerCall and should only be used for flat ground polygons, not for 3D objects. When it is used FS doesn't know it's a 3D object and that is the cause of your problems.You should use a PerspectiveCall or ADDOBJ command to tell FS that it is 3D. You can not provide a layer number (the parameter 8) with that command.Then back to the cause of your problem. I think GMax uses the RefPoint type 7 as we called it in SCASM, that means that the RefPoint is placed at the altitude of the DEM (for that certain point).If this causes problems you could try two things I think. One is to flatten the water below it, so there is no height difference under the bridge, or just raise the bridge a bit in altitude.Arno

Thanks Arno,I think I'll try the flatten code and see how that works.I hope I have six left!!!!!!!!!!!!http://members.rogers.com/jkanold/jimlogo.gifhttp://members.rogers.com/jkanold/flyurl.gif
