2022-11-11Fix broken Cycles rendering with recent OSL versionsPatrick Mours
Commit c8dd33f5a37b6a6db0b6950d24f9a7cff5ceb799 in OSL changed behavior of shader parameters that reference each other and are also overwritten with an instance value. This is causing the "NormalIn" parameter of a few OSL nodes in Cycles to be set to zero somehow, which should instead have received the value from a "node_geometry" node Cycles generates and connects automatically. I am not entirely sure why that is happening, but these parameters are superfluous anyway, since OSL already provides the necessary data in the global variable "N". So this patch simply removes those parameters (which mimics SVM, where these parameters do not exist either), which also fixes the rendering artifacts that occured with recent OSL.

2022-02-11Cycles: use SPDX license headersBrecht Van Lommel
* Replace license text in headers with SPDX identifiers. * Remove specific license info from outdated readme.txt, instead leave details to the source files. * Add list of SPDX license identifiers used, and corresponding license texts. * Update copyright dates while we're at it. Ref D14069, T95597
2022-01-13Fix T94737: Cycles wrong normal map normal with OSLBrecht Van Lommel
Ensure valid reflection was moved elsewhere, should not be done in the node anymore.
2021-10-26Cycles: changes to source code folders structureBrecht Van Lommel
* Split render/ into scene/ and session/. The scene/ folder now contains the scene and its nodes. The session/ folder contains the render session and associated data structures like drivers and render buffers. * Move top level kernel headers into new folders kernel/camera/, kernel/film/, kernel/light/, kernel/sample/, kernel/util/ * Move integrator related kernel headers into kernel/integrator/ * Move OSL shaders from kernel/shaders/ to kernel/osl/shaders/ For patches and branches, git merge and rebase should be able to detect the renames and move over code to the right file.
