Bug: Compositor Texture References

[donvitoni]

Hi everybody,

Problem: Textures that refer to other Textures in a CompositorsChain can not be fetch with CompositorInstance::getTargetForTex(const String &name)

Example (see below): Compositor CompA has a Texture CompATexture. Composior CompB has a Reference named RefToCompATexture to CompATexture.
CompositorInstance::getTargetForTex(const String &name) will throw an exception if i search for CompATexture in CompB, because it only looks after the name of the texture in reference compositors, not for the reference name

Code: Select all

compB->getTargetForTex("CompATexture"); // -> will succeed
compB->getTargetForTex("RefToCompATexture ");// -> throws exeption

Change: The changes for that where impl in Rev: 2f9cdde4bb45321ce6e2f8c3eca41aa990280efe . https://bitbucket.org/sinbad/ogre/chang ... 9cdde4bb45

A patch is here: https://sourceforge.net/tracker/?func=d ... tid=302997.

Code: Select all
