Well, from SU (Pro), you can export pdf as "2D graphic". As far as I know, this can be opened in PS and the pdf graphic export from SU is vector based (i.e. no raster jagginess at all).

Also, when you are in LO (and please, do not discard it yet), you can turn your rendering either to vector or hybrid mode and then the export will also be vector based (for the edges).

Please, have a look at this post in the LO forum:

It explains exactly the same.

Um.. I do need to ask if your reply was an answer to the SU to PS question or SU to Layout?

Well, I was referring to LayOut (it is a "paper based" app so there is paper there while in SU, it is only for printing). But eventually, when you are already at vector based drawings, paper space (in PS) will also be a useless term. But in any case, in LO you can define paper sizes and dpi settings and 2D export resolution will be adjusted to your settings if you export raster (with vector, again, resolution does not mean anything)

You are right. A transparent material (with a transparent image) does not receive shadow (just casts shadow). Sorry, I was wrong.

And you are also correct that it does not receive shadow over 70% opacity. It only casts shadow when it is over. I do not know why I remembered incorrectly.

In this case however, I can see no way you can cast shadow on a transparent surface - unless you draw the outline of the (supposed to be) shadow and make it darker this way "baking" it in the model. But of course, that will never be interactive (like when you change the sun position).

Teo, I'm glad that worked out for you.

Your boat looks nice. When I get closer to building the faering, I'll get in touch. I'm sure I could learn a lot from you.
