Previously, conditionals set on the shader would change outside of the
_render_list function when blend shapes were used
This is an issue because the function keeps track of the previous shader
state to try to minimize state changes
Now we keep all this shader state change within the _render_list
function to ensure the saved previous state is correct
Adds fixed timestep interpolation to the visual server.
Switchable on and off with project setting.
This version does not add new API for set_transform etc, when nodes have the interpolated flag set they will always use interpolation.
Wrapper functions for uploading buffers to OpenGL take all sizes and offsets in bytes. Some buffer sizes are specified as units (e.g. float) so require conversion to bytes when calling the buffer upload functions.
Two such bugs have been fixed in blendshapes, and parameter names and comments have been changed to emphasize that sizes should be in bytes.
In addition DEV_ASSERTS in the upload wrappers have been changed to ERR_FAIL.
Using codespell 2.2-dev from current git.
Added `misc/scripts/codespell.sh` to make it easier to run it once in a
while and update the skip and ignore lists.
(cherry picked from commit 1bdb82c64e)
- Prevent debug enforced use of ubershader on shaders not supporting it
- Use unsigned integer for ubershader flags
- Add project setting for disabling async shader compilation on mobile
- Stop sampling some textures through different kinds of samplers at the same time
When editor continuous redraws is switched off, the editor only redraws when a redraw_request was issued by an element in the scene. This works well in most situations, but when scenes have dynamic content they will continuously issue redraw_requests.
This can be fine on high power desktops but can be an annoyance on lower power machines.
This PR splits redraw requests into high and low priority requests, defaulting to high priority. Requests due to e.g. shaders using TIME are assigned low priority.
An extra editor setting is used to record the user preference and an extra option is added to the editor spinner menu, to allow the user to select between 3 modes:
* Continuous
* Update all changes
* Update vital changes
Blend shapes did not take into account octahedral compressed vertex
attribute layouts and this resulted in incorrect lighting on the
resulting blended mesh
Now make the blend_shapes shader octahedral compression aware!
The "webgl/webgl2.h" include provides that function, but it's not
available in emscripten versions < 2.0.17 .
Since we need to support emscripten 1.39.9 (mono builds), this commit
adds a JS function in library_godot_display.js as a compatibility layer
for it, and implement glGetBufferSubData by funneling the call to that
function (so we don't have name collisions JS-side with recent emcc).
All those hacks are now moved to the platform directory instead of being
ifdefs inside the drivers implementations.
Applying overlay materials into multi-surface meshes currently
requires adding a next pass material to all the surfaces, which
might be cumbersome when the material is to be applied to a range
of different geometries. This also makes it not trivial to use
AnimationPlayer to control the material in case of visual effects.
The material_override property is not an option as it works
replacing the active material for the surfaces, not adding a new pass.
This commit adds the material_overlay property to GeometryInstance
(and therefore MeshInstance), having the same reach as
material_override (that is, all surfaces) but adding a new material
pass on top of the active materials, instead of replacing them.
Implemented in rasterizer of both GLES2 and GLES3.
Async. compilation via ubershader is currently available in the scene and particles shaders only.
Bonus:
- Use `#if defined()` syntax for not true conditionals, so they don't unnecessarily take a bit in the version flagset.
- Remove unused `ENABLE_CLIP_ALPHA` from scene shader.
- Remove unused `PARTICLES_COPY` from the particles shader.
- Remove unused uniform related code.
- Shader language/compiler: use ordered hash maps for deterministic code generation (needed for caching).
For octahedral compressed normals/tangents, we use vec4 in the shader
regardless of whether a normal/tangent does/doesn't exist
For the case where we only have a normal vector, we need to specify that
there are only two components being used when calling glVertexAttrib
Before we would always specify that there were 4 components, and used
offsets to determine where in the vertex buffer to read data from but
this doesn't work on all platforms
