Hi, i am a bit stuck with this, all seems well except for this does anyone have any idea, i am using iradiance map for primary and light cache for secondary kent

it looks like you might be using only an HDRI to light the scene. that is only half of the solution. you will still need an actual sun source.

thanks for the reply travis I am not using a hdri but you might be right i will try a sun source and see if that is any better, as a matter of interest i have the primary bounces set to 1.7 and do not have any other light source so wiil give what you suggested a try kent

Hey Travis that worked put a direct light in and wacko all better actually gives more depth to the whole scene thanks on on kent

looks like a geometry issue, have you 2 coplanar faces in the same space ?

were you using a GI enviroment?

 

...basically, it looks like you only have a GI solution. it is difficult to impossible to get good shadowes with only a GI solution. a GI solution only provides skylight, light reflected off of the atmosphere byt he sun. it does not provide sunlight itself. to get sunlight you still need to add a light source for the sun in addition to the GI solution.
