HDRI Help

Hi -

How do I position my characters when using an HDRI? They are never on the ground or where I want them to be.

Thanks

    Switch to FInite Box in Envronment. Adjust the ground position manually. Use NVidia Iray preview in viewport or filimant so you can actually see the background and make adjustments.

    I am still trying -

    The only thing I can do is rotate the dome. I use Dome Origin and it does not do anything. I use Dome Orientation and it rotates the X and Z axis and moves the Y. I am still not getting the ground where I want it.

    Thanks

    Move the camera and the figures not the dome.

    I am also looking at these settings definitions to try and figure this out but nothing is moving.

    Here are two angles showing it way off the ground

    I have the exact same everything after moving the car and model -600 on the Y axis.

    What is the Ground Position Mode set to, once you have the Environment Settings node?

    Hi - I tried on both manual and auto and I get the same results. Thanks

    In the first two images the ground plane isn't on the HDRI ground,  the ground plane is too high and the next one the characters are below the ground.

    Set everything to zero. If the vehicle is floating or the ground plane isn't on the ground raise the camera up and then tilt it forward until it is. The car should now be on the ground.

    If you want a different view of the background spin the camera or zoom it and move the car left/right/back or forward to get it positioned.

    Don't move the HDRI or you will have to start again.

    Everything is set to zero. I even deleted and started new with being all default. Still same issue. It's got to be something simple I am messing up.

     Here I loaded the HDRI then the Jeep. I spun the camera to get the road in view then clicked the Jeep and the Centering Icon, the square box with the cross in it, to centre the camera on the jeep. I turned the jeep and moved it left/right and back to get it on the road. I moved the camera up for a better angle and moved it back a little to get all the jeep in. I rendered without doing anything else.

    Cool, almost convincing except the jeep is still floating an inch or so in the air. You can adjust the ground position up and down.

    Also I couldn't fathom how it go there without leaving tire tracks and wheels not being covered in mud and leaves...but hey I'm sometimes too picky.

     It isn't a render it is a test, or perhaps you are just too picky.

    One major problem with filament (you seem to use it for your previews) is that it does not render all possible settings of the dome!

    For example Ground Texture Scale has no effect in filament. I usually set it to match the height of my camera as a start.

    Try the following:

    1. Start a new empty scene
    2. Add a camera
      1. Set the following camera properties to 0 and lock them (to not accidentally change them, because this usually gives weird effects with the HDRI):
        X Translate
        Z Translate
        Z Rotate
      2. Guess at which height the center of the panorama is. I start with average eye level of 150 cm
    3. Switch to Environment Options and set the following parameters
      1. Dome Mode ► Finite Sphere w/ Ground
      2. Draw Dome ► On
      3. Select the Environment Map (For first experiments choose one with flat ground in the center I used https://polyhaven.com/a/autumn_crossing)
      4. Ground Texture Scale ► Your guess from the camera eye level above (150)
      5. Draw Ground ► On
      6. Ground Position Mode ► Manual
    4. Place your object in the scene
    5. Move your object into the view
    6. Change your available free camera parameters
      1. Y Translate (after changes you usually need to change also Ground Texture Scale)
      2. Y Rotate
      3. Z Rotate
      4. Focal Length
    7. Go back to 5.

    This is an example scene with the obove mentioned HDRI and the car Ranger you use:

    https://polyhaven.com/a/autumn_crossing

    The path of the HDRI  in my DUF scene file will most likely not match your download location. You should be able to change it afterwards by opening it maniually.

    I like that Autumn Crossing HDRI I did this one a while ago. The only geometry is the girl, the horse, the leaves under the hooves and the shadow catchers on the seat :)
