Change [Object] > [World]
Drag a HDRI into the material editor and connect it to the background node.
Strength = 1
[Clipping End] needs to match scale of objects in scene.
[Softness] controls hard/soft shadows.
Add 3 more lights. Vary color and strength.
Problem #1 – Not sure why at certain camera angles the sea object shows this gray area. IOR or PBR roughness causing reflection rather than refraction when looking alongside rather than directly at surface ?
Problem #2 – Not sure why in this render the shadows on the front walls of the seashack look distorted ?
Solution #2 – Camera object – Clip range changed from [0.1m – 1000m] to [1m – 1000m] solved the issue. Not sure why.
Problem #3 – I had a lot of problems editing the boat object once it was rotated along Z. After a while, the local coordinate system’s X and Y axis did not line up with the boat object any more. I was unable to move vertices along local X or Y. I don’t know what caused this. I was unable to fix local axis alignment. I don’t know how to rotate an object’s pivot as you do in 3dsmax.
Solution #3 – There is no rotate pivot. To fix, manually rotate your object in line with world X,Y,Z axis. Apply rotation. Fixed. Now you can rotate object and use [G], 2x [X or Y or Z] to rotate along correct local axis back to desired position. Or use this. Local axis change either by resetting rotation or by joining objects.
Problem #4 – On a number of occassions when trying to enter values in input fields, it turns out I did not have input focus and pressing number keys 1-9 (not NUMPAD keys) caused a large number of collections in the Outliner to be ticked as Hidden in Viewport. ‘Unhide unselected’ does not fix this. I don’t know how to Show All in Viewport in Outliner with a single keyboard shortcut.
Solution #4 – When in the Outliner, use [SHIFT]+[LMB] or [CTRL]+[LMB] and click on eye symbols to View All in Viewport. Also, click (repeatedly) on [NUMPAD+] and [NUMPAD-] to expand/collapse all collections 1 level.
