Since we are removing `scene.use_nodes` in #143578, most developers
will have to update their python script by replacing `scene.node_tree`
by `scene.compositing_node_group` in order to create a new compositing
node tree anyways. So we remove `scene.node_tree`.
Note: `scene->nodetree` in `scene_blend_write()` is still being written
to the blend file, so forward compatibility is not affected by this PR.
Pull Request: https://projects.blender.org/blender/blender/pulls/143619
Previously, when a file output test failed, all images within the same
test case were updated, even images that did not cause the test to fail.
This patch only updates changed/removed images so when the test is run
using `BLENDER_TEST_UPDATE=1 ctest -R compositor_cpu_file_output` git
will only show the modified, added or removed images
Pull Request: https://projects.blender.org/blender/blender/pulls/134852
The patch adds a simple framework to test the File Output Node in the compositor. The main difference to the existing `render_test.py` framework is that multiple output images are supported. Edge cases such as empty output or too many outputs are supported as well.
Tests can be run like other compositor tests, e.g. `ctest -R compositor_cpu_file_output --verbose` or `BLENDER_TEST_UPDATE=1 ctest -R compositor_cpu_file_output` to update failing tests.
