Fix: Update normals when switching scene quality

Recent commits also updated normals for metaballs, curves and volumetric
objects. This change tags will tag to generate geometry for these new

Fix T84397: Creating and removing many objects very quickly causes a crash

The root of the issue was caused by the dependency graph using ID pointer
to map evaluated state from old depsgraph to new one upon relations update.
This was failing when IDs were re-allocated rapidly: was possible that
Object ID's evaluated state assigned to Mesh and vice versa.

Now depsgraph uses Session UUID to identify which IDs to restore evaluated
state to. The session UUID is stored in the IDNode, so that id_orig is not
dereferenced on depsgraph update since the ID might be freed.

The root of the issue is identified by Campbell, original patch was done
by Bastien, thanks! Also thanks to Oliver and Ray and everyone else for

Fix T84459: Wireframe not displaying with AMD GPU

Issue appears to be caused by AMD graphics driver later than 20.11.1 and
affects older GPUs (Polaris/FIJI cards). Wireframe drawing uses the same
OpenGL data type for storing normals what is known to be faulty.

This patch enabled storing the normals using GPU_COMP_I16. It also
solves the normals drawing in edit mode for vertex and loop normals.

Fix T84459: Face normals not displaying (AMD GPU)

This is part two of the fix for T84459.

uses the same OpenGL data type for storing normals that is known to be

This change fixes the face dot normals by using GPU_COMP_I16.

GPU: Enable HQ normal work around for AMD Polaris

THe high quality normals work around is enabled for Polaris cards using
the official drivers. Since driver version 2.11.2 they fail to render
using low quality normals.

The detection of polaris cards is done by matching the opengl renderer.
The renderer strings have been extracted from various reports linked to
{T82856} but isn't complete as some reports are missing the exact
renderer as users don't always report via the help menu.

GPU: Add HQ normals workaround.

This change makes it possible for platforms to only support high quality
normal rendering. This is part of {T82856} where current AMD drivers
running on the polaris architecture does not support the low quality
setting due to a driver bug.

In a next commit the work around will be enabled.

DrawManager: High quality normals for non meshes

This adds high quality normals for non meshes. These include

* Volumetric Object Wireframe
* Metaballs
* Extracted Curves
* Curves in edit mode

This is in preparation to fix a regression in recent AMD
drivers where the `GL_INT_2_10_10_10_REV` data type isn't
working in Polaris cards.

Fix T83625: Shading attribute names cause compilation error.

Some GPU platforms don't support having more than one underscore in
sequence in an attribute name. This change will remove the underscore
as a possible character when encoding to save names.

Fix T83280: Crash when deleting hair collision collection.

Root of the issue was missing management of ID pointers in the cloth
modifier data stored in ParticleSystem for hair physics, in the
'foreach_id' particle system code.

Using modifier's 'foreach_id' code in psys one unfortunately requires
some ugly conversion gymnastics, but this is still better than having
dedicated code for that case.

Note that this is actually a fairly critical issue, fix should be
backported to 2.91.1 should we do it, and to 2.83 LTS as well I think.

Steam Release: Script creation of Steam build files

Script tool for automation of Steam build files for tasks like {T77348}

This script automates creation of the Steam files: download of the archives,
extraction of the archives, preparation of the build scripts (VDF files), actual
building of the Steam game files.


* MacOS machine - Tested on Catalina 10.15.6. Extracting contents from the DMG
archive did not work Windows nor on Linux using 7-zip. All DMG archives tested
failed to be extracted. As such only MacOS is known to work.
* Steam SDK downloaded from SteamWorks - The `steamcmd` is used to generate the
Steam game files. The path to the `steamcmd` is what is actually needed.
* SteamWorks credentials - Needed to log in using `steamcmd`.
* Login to SteamWorks with the `steamcmd` from the command-line at least once -
Needded to ensure the user is properly logged in. On a new machine the user
will have to go through two-factor authentication.
* App ID and Depot IDs - Needed to create the VDF files.
* Python 3.x - 3.7 was tested.
* Base URL - for downloading the archives.

Fix T82729: Crash in rna_EffectorWeight_path when object has fluid and dynamic paint modifiers

Looks like prior to the introduction of mantaflow, the former
SmokeModifierData always had a domain initialized (even if its type was
set to None). Since mataflow, the FluidModifierData type needs to be set
to MOD_FLUID_TYPE_DOMAIN (otherwise domain is invalid)

Fix T83055: setting rna pointer properties can create bogus custom properties

This was reported in the form of the eyedropper of the 'Parent' property
creating a custom property 'parent' if self was picked.

Problem arises when certain checks for setting rna pointer properties
failed (for example: the PROP_ID_SELF_CHECK check) and then a different
code path was entered (which was only meant for IDProperties).

Problem was introduced in rBa7b3047cefcb.

To solve, now first enter the branch for rna-based pointer properties,
then perform the sanity-checks (and if these fail: dont enter the other
unrelated codepath but instead do nothing)
