hey guys,

i have been trying to take c4d camera with the animation to houdini, so i can make a scene in houdini,i exported an FBX formate and its working great, but the objects and simulations are too small when i try to add anything, note that i don't want to change the Zoom settings or anything in the camera that i exported from C4D as i want the animation of it, but just to add Geo to the scene with the proper scale ..

is there any orientation settings or distance measure that i can change so i can achieve the proper scale ?

What do you mean? Either make bigger stuff, or don't make your camera so far away.
