shadow and raytrace

i tested some shadows on simple model here

see pics

in first image i did set shadow on all objects and we can see the hadow on the floor
but the yellow does not receive a shadow from red block why?

in second case i had to add tnagent in F5 to get the shadow on the yellow block !

Thanks

You forgot the pics I thinkā€¦

yes your right

here it is

now i added some pics and seems that
when you have 2 bock it takes into consideration only the first bock
no shadow from second block with lamp or spot light

thanks

seems that to get snadows from second blocl you need to set spot light with ratrayce

not shadow buffer
see pic

but again this is not giving a second clear shadow only the one from the front blocl!

Thanks
