How to use CAD Assistant for ray tracing/photo-realistic rendering

Maybe this video tutorial will help to do first steps.

Thank you it helps but this is not complete tutorial and I cant learn everything from here. Is another source for it?

I don't think there is another tutorial. But you may ask questions at which step you need a help (what doesn't work, what cannot be found, etc.).

for example I dont know how to add and position light, and sometimes I can apply material some times cant. And how to save result as png. And how to add custom background?

I'm not familiar with lighting in CAD Assistent. But as for a saving into PNG. You just need to save scena. It is possible to do by clicking on Button ("Save or send file or snapshot").

Best regards, Commenter-2.

can you check my other question? I uploaded example about what is not working

for example I dont know how to add and position light

Well, you can't :(. CAD Assistant has no interface to add arbitrary light sources - you may change only directional light and ambient light.

and sometimes I can apply material some times cant.

Probably this needs some model samples to see what might be wrong...

Thanks for your replies but what about custom background?

Sorry wrong topic I did this comment.
