is it a specular mat ?
I have strange behaviour with specular / cast shadow / fake shadow
Nope, it's a diffuse material with bitmap as a diffuse texture. Nothing special.

It's not working for me.

Cast shadow option works only with emitters, direct sun light and environment light with image texture and importance_sampling enabled.

What is the problem?
You didn't attach hdr file.
I used my.
Don't forget that some part of light can be shadowed due to GI effect of multiple light reflection between objects.

sorry
hdr is just a white plate
here is the result and the hdr file. What is it ? if not a shadow.
As far as I'm concerned, light should pass through an object that doesn't cast shadow.

OK I just understand what you mean.
The darkest part is the true color of the material and the lightest part is du to light bounce.
I apologize.

I will think how to take more shadow sources into account.

Thank you for the answer. I clearly stated in one of my postings, that it does not work with sunlight.
Here's the screenshot again in case you missed it on the previous page. I'm telling you, the feature is buggy in my workstation.

I found out the problem - it's not working when the model is movable proxy. So there you go - that's the restriction.

That is a bug.
