Click VRayPhysicalCamera01 and a menu will appear… An ant trail will follow the mouse cursor.Select Target Distance in the menu that appears.Right-click the ZoomAndFocusCam_01_Camera in the scene and select Wire Parameters. Next is to link the Target Distance values of the two cameras.Change the Lens: value to the same as the film gate (mm) value of the VRayPhysicalCamera that was created previously. Select ZoomAndFocusCam_01_Camera and go to the Modify tab.Here we select the Craft Zoom&FocusCam but any camera can be combined with VRay’s cameras. Also note that its film gate (mm) value is set to 36. Disable the targeted checkbox so that the VRayPhysicalCamera isn’t pointing at a target.VRay – Combining Craft Cameras with VRayPhysicalCamera in Autodesk 3ds Maxĭescription: The guide below will show how to connect a Craft Camera together with VRayPhysicalCamera. PCont.particlePosition = previousParticlePos + (particlesSinceLastDrop_int + 1 - i)*(PFSource.pos - previousParticlePos)/(particlesSinceLastDrop) PCont.particleTime = previousParticleTime + (particlesSinceLastDrop_int + 1 - i)*(sTime - previousParticleTime)/(particlesSinceLastDrop) ParticlesSinceLastDrop_int = particlesSinceLastDrop as integer ParticlesSinceLastDrop = ((length (PFSource.pos - previousParticlePos))/distBetweenParticles) as float PFEuler = PFSource.rotation as eulerAngles PCont.particleIndex = pCont.NumParticles() - last particle that was added PreviousParticleTime = pCont.particleTime PreviousParticlePos = pCont.particlePosition

Global initFrame = 40f -sliderTime as float

Before rendering you must play back the whole scene for the particles to be correctly cached.Īlso play back with “Real Time” unchecked in the “Time Configuration” dialog.

Set the distance to be slightly smaller than your geometry.

Change $’PF Source 01′ to the name of your PF Source.

Below in the “on Init pCont do” function set the “initFrame” as the start frame.

For geometry create an instance of your tire track and replace Shape with Shape Instance and select the instance you wish to output, eg a face with your track mark.

Add a Cache operator and set it to “use at: viewport/render”.

Press the “edit script” button and replace the code with this code.

For each PF Source Replace the Birth operator with a BirthScript operator for the PF Source in the Particle Flow dialog,.

Description: This is a script that can be used to generate tire track particles.Create a PF Source for each tire and place it slightly above the tire bottom and then link the PF Source to the respective “WheelCenterMesh”.
