Mapping: Advanced 3DsMax Lightmapping

What are the problem with offset of objects shadows on terrain lightmap?
UV Vertices are on right positions.
And with Ray Traced Shadows tree shadows are cast only like points, also slightly offset

Problem of slightly offset is my bad - "...Convert your terrain back to an Edible Poly and then apply an "Unwrap UVW" Modifier to it. Click the Edit button in the modifier panel, go to face selection mode, select all faces (Ctrl+A) and then on the right in the modifier panel, in the Map Parameters rollout, hit the "Planar" button with "Normalized Map" Checked and it will UV your terrain in the same way it is ingame. Make sure that the North of your map is in the top of the UV etc. Once your happy click on the "Planar" button again and you can also uncheck "Show Pelt Seam" and "Show Map Seam" in the Display roll-out above it to make for easier viewing. Finally double check that your UVs are extended all the way to the very edge of the UV box, Best way to do this is to select the bottom left UV Vert, and ensure its at "U: 0.0, V: 0.0" and that the very top right vert is at "U: 1.0, V: 1.0". If the UVs do not extend to the very edges of the UV Window, then your generated terrain shadows later will be slightly offset from the objects of the map, especially at the edges of your map, and there will be a big gap around your map edges of a missing generated lightmap..."

Problem with Ray Traced Shadows exist because on 3ds max 2018 isnt present Mental Ray.
https://nvidiamentalray.wordpress.co...ia-mental-ray/ - install 3ds Max 2018 – Plugin MRMAX2018_v1.0.exe and Mental Ray Standalon(Satellite installer) MRMAX2018_Satellite_Installer_1.0.exe.
