Today, Shadow casting is implemented only through use of skeleton. Shadow receiving is implemented only for Landscape. In other words only the landscape can receiving shadows.

 

Moreover, Skeleton casting is possible only with:

- not MRM sticked shapes (eg a sword sticked to a hand bone with USkeleton::stickObject() )

- MRM skins shapes THAT MUST BE PROCESSED before with the tool nel\tools\3d\build_shadow_skin

 

The enableCastShadowMap(true) has no effect on Light. All lights project shadows (yes, it could be a cool feature to disable some lights)

 

Once your skins are processed with the build_shadow_skin tool, the only thing you have to do at execute time is:

 

Skeleton->enableCastShadowMap(true);

Landscape->enableReceiveShadowMap(true);

 

NB: a basic not optimized support is also provided for simple mesh not MRMed, nor SKINNED. So it should work with a simple mesh (eg a car) as long as you do simpleMesh->enableCastShadowMap(true);

Hi,

 

we are looking at creating the dynamic shadows for an entity and need some information on

how nel handles this we have observed the flags on entities landscapes and lights

 

 EntityMesh->enableCastShadowMap(true);
 EntityMesh->enableReceiveShadowMap(true);

 

on the entity objects

 

 Landscape->enableReceiveShadowMap(true);

 

on the landscape

 

 PersonalLight->enableCastShadowMap(true);

 

on dynamic lights

 

is there something specific we need to do to make the entity cast a shadow?

any advice would be greatly helpful thanks
