Using HDR Image makes real world scale architectual model float I completed a real world scale architectural (units = feet) that was exported to FBX and then imported into blender for rendering purposes. The model looked great and I needed to finally add an HDR image prior to rendering. My issue is the image looks HUGE compared to my 3D model which checking scale by creating a plane object representing the extents of my model and this looks good to the model but to the HDR image 2 things are easily noticed. 1. Trees and buildings in the image even off in the distance are bigger than my model. 2. my model floats above the ground of the image so even positioning the camera you can tell the model is floating and just doesn't look right.

I tried to scale and reposition but this just hoses the appearance of the image.
Is there anyway to correct this and make my model appear on the ground of the image. I got the image from HDR Haven recommended in tutorials I have watched and with architectural models appears it is sitting on the image ground without any adjustment of the image or the model that is sitting at 0,0,0 location.

Other thing I noticed when zooming and panning is model is getting clipped which doesn't happen when image is removed.

TIA!

Cheers!

The HDRI is rendered at infinite distance. When trees appear too large then this is because the panorama was taken at a close distance to the trees. What you could do is either set the background to transparent and composite with one of the backplates provided with the HDRI (this allows some cheating with the scaling during compositing) or chose an HDRI with realistic dimension that depicts a place with enough free space to actually build a house. For example this one.
