Shadows are shifted
Hello!
I have this problem with Twilight V2 renderer in Sketchup Make 2017. I tried all options i could think of but i still get this shifted shadows. Anyone knows how to fix this?
Left one is just a simple box, and the two right are stacks of thin boxes. They all are touching the surface plane which is just one big square face. I tried enabling Corrected Shadows but the result is the same.

Also tried changing a focal distanse of the Twilight lens from 100mm to 50mm and the results looks like this. A little better but the stack shadows are still off. Anyways this does not fixes the problem because i'd like to use a longer focal distance.

Re: Shadows are shifted
I recommend using a different render method. Try Interior. The Low/High methods are "biased" and that means they use certain assumptions and the thin layers may be conflicting with that. Interior on the hand is more of a direct evaluation and you should get more accurate lighting results.

Re: Shadows are shifted
Thank you for the answer!
Unfortunately this doesn't help. I tried Exterior before posting the problem here and now i tried interior and interior+ — the same thing. I guess there is a problem elsewhere. Thin layers of cards stacked cause the self shadow to offset down. But the cast shadow of solid block (left one) is still shifted from the corner.

Re: Shadows are shifted
I tried to widen a focus distance even more (35mm) and the shift is almost not there. So i guess this has something to do with the focus length.

Re: Shadows are shifted
That is strange. What kind of material are you using?

Re: Shadows are shifted
At first I used a Flat template for textured surfaces and a default for untextured white ones. But as you mentioned the materials I made a special material for white box sides and also assigned a Flat template to it. No luck again
Re: Shadows are shifted
Select all - scale up by 10x - reposition camera - render.
If still not accurate enough - repeat and render again.
I had same issue, then scaled up 10x, and got this on Low+ render setting.

Re: Shadows are shifted
Yes, this does the trick. Thank you! That's a pity you have to work around for it this awkward way.
