[1.12.1] Casting shadows and Object visibility Topic is solved

Operating System: :Ubuntu 16.04:
Render System: :OpenGL:

Hi

I have an application in which I render the same scene in multiple windows using different cameras.

An object may be visible in one window but not another. To do this I use the entity Ogre::Entity::setVisibilityFlags() (ie Ogre::MovableObject::setVisibilityFlags()) and use appropriate visibility flags for the camera in use.

I can change the object visibility ok and I see the object disappear and reappear as desired - all ok with the exception of the shadows cast by the object which stay visible even when the object isn't. I can turn off the object shadows using Ogre::Entiry::setCastShadows but that applies it to all windows (cameras).

The scene manager uses SHADOWTYPE_TEXTURE_MODULATIVE shadow technique

Is there some way or strategy for turning on/off casting of shadows on a camera basis for a single object?

Come to think about it, shouldn't the shadow not be rendered automatically if the object is not visible by the current camera? Isn't this possibly a bug?

Thanks

try Viewport::setShadowsEnabled: https://ogrecave.github.io/ogre/vtests1 ... tNoShadows

altough I need to check the mask handling with shows too

edit:
can you try adding:

Code: Select all

shadowView->setVisibilityMask(vp->getVisibilityMask());

here https://github.com/OGRECave/ogre/blob/b ... r.cpp#L873

and see whether it just works without other changes?

Great! That worked perfectly!

Many thanks paroj
