HDRI problem Thea render
-
I'm not sure that your hdri has the best quality...
I can only encourage you to try this scene, where you can take learnings from the material settings etc...
(NB! please note the file-size is 83Mb, because it also contain a free hdri...)With the scene you should be able to get a render similar to this if you're using the latest Thea4SU plugin...
-
Thank you very much for your concern, I'm trying.

Tomasz used frontal projection with his scene
quick tut:
Setup you scene with the car on a plan add the hdri,
scale the plane so it reaches the horizon
Hide everything and render the scene, save the image
unhide everything
add the previously rendered image to the plane
open the thea dialog and double click on the image
set the diffused slot projection to frontal
close the mat lab
do a test render, you'll find the background is slightly darker, set the background intensity to about 1.7, you may need to fiddle about a bit
thats it
Here's the Thea version as a pack file, I don't have the SU file on this laptop
pack file -
not in the same way as in sketchup shadow thea?

You're mixing things up...
Please remember that the hdri will also be a source of the illumination...Please take the advice Nigec have provided...
-
If you want silhouette shadows is Thea, using frontal projection is the way to do it. But if simple "attaching" a model on a HDRI is enough then using shadow catcher is must.
-
No you don't use a shadow catcher at all, it uses the actual geometry with a texture
here's a SU version
Su fileyou can also add bump, and reflections, but you need to use masks

Attached please find a very simple model with some spheres...
THe render was complete in 16 seconds using the BSD preset...I've used the "Harbor 3" hdri from the HDRI Hub IBL package, which is free to download for registered users...
Hope this can help you further...?!?
