ogre-next createEntity(SceneManager::PT_SPHERE) crashes

[jordiperezarti]

v1::Entity *ogreEntity = sceneManager->createEntity(SceneManager::PT_SPHERE);

Crashes with no output to log, when root is initialized, window created...
loading .mesh is right, is when creating a prefab that crashes.

Any idea?

Hi!

Do you have a callstack when the crash happened?

The last step seems setting the default material to the sphere, but no one is defined.
How do i define the default material? (i am using the unlit shader lib)

[dark_sylinc]

It looks like you're calling createEntity() before HlmsPbs is setup.

If you don't use HlmsPbs, you can call HlmsManager::useDefaultDatablockFrom to use a different Hlms that's already set.

[jordiperezarti]

mngHlms->useDefaultDatablockFrom(hlmsUnlit->getType());

This avoids the crash.

Thanks.
