Revision 3bc4423 by Kévin Dietrich (master) May 2, 2021, 23:21 (GMT) |
Cycles: use reference count to detect used shaders Shaders are only compiled if they are used by some other Node (Geometry, Light, etc.). This usage detection is done before updating the Scene, however it fails at detecting Shaders used by Procedurals not known to Cycles (e.g. ones defined by third party applications), as Procedurals are only updated after the shaders are compiled. To remedy this, we now use the Node reference counting mechanism to detect whether a Shader is used and therefore should be compiled. This removes `ShaderManager::update_shaders_used` as it is not needed anymore, however, since it would also update the Shader ids, this is now performed in `ShaderManager::device_update`, and a new virtual `device_update_specific` method was added to handle device updates for SVM and OSL.
