Adds `_xvk_tex_rotate` field for surface patches. Angle is specified in
degrees.
Note that it rotates the texture around origin, which might be very far
away. So offset patching might be needed to re-align.
When texture coordinates are inverted, it makes tangent look into
oppsite direction, which inverts TBN and therefore normal map.
Make sure the tangent points to a consistent direction.
Fixes#627
Uses `_xvk_smoothing_excluded` field.
Surfaces can still be smoothed with a limited list of neightbours explicitly
by being included in a smoothing group.
Fixes#619
Use dedicated hash table for new material names.
Updates a lot of dependent code:
- surface patches now target materials, not textures:
`s/_xvk_textures/_xvk_material`
- patching now affects only materials, not texture ids. All logic that
depends on texture ids now operate on original textures.
- brush normal smoothing now ignores patched surface materials when
deciding whether two surfaces can be smoothed.
The rationale is that patching should only affect newer PBR/RT code paths.
kRenderTransColor mode strips geometry of its texture and makes it solid
color. Previously we were noticing this rendermode late, and failed to
update the textures.
Now we depend on reading this rendermode from map entities, and
pre-assigning correct (white) textures on load.
Assumes that rendermode doesn't change at runtime for brush models.
Fixes#528
Different render sources (model types, render types, etc) might require
different material modes. E.g. brush should be translucent (refractive+mirror)
for blend mix modes. However, smoke particles should not be
mirror/refractive for the same blend mix render type.
Needed to hide invisible geometry on e.g. c5a1. Breaks de_dust2 roofs
(#474). That will need to be addressed some other way.
Still uses special value for base_color texture to signal SKY SURFACE.
A supposedly better way to do this would be to have them have a special
material.
1. Completely remove them from geometries
2. Draw skybox where the ray hasn't hit anything
3. In the same fashion sky is not shadowed when there's nothing hit by
the shadow ray.
This allows completely removing the sky material flag.
Also supposedly fixes#474
This is needed to enable advanced material patching, where the material
can be picked up based on source type, render mode, surface number, etc
etc and all of the above combined if needed.
Previous scheme was picking up materials very late when all of this info
has been already lost.
Do not aggravate the validator by uploading to the same memory region twice. Make sure that there's synchronization between updating kusochki.
Fixes#553
This doesn't work as expected in some cases, as surfaces might still get
linked transitively by neighbours. Solving this seems non-trivial for
now, but maybe we can just live with it
Automatically smooth normals between surfaces with normals less than 45
degrees off.
Can be adjusted from map.bsp.patch file like this (e.g. to 50 degrees):
```
{
"_xvk_smoothing_threshold" "50"
}
```
Renames previous METRICS to COUNTERS. These are still reset to zero
every frame.
Adds new METRICS which are preserved, maintained externally to speeds,
and only sampled by speeds code once per frame.
Also adds new metrics:
- `studio.cached_submodels` -- number of submodels in cache
- `geom.used` -- memory used by long allocations
- `geom.{vertices,indices}` -- counts of vertices/indices for long
allocations
- `geom.dyn_{vertices,indices}` -- counts of vertices/indices for
single-frame dynamic allocations
- Add variable name and registration src:line to the
`r_speeds_list_metrics` output. Makes it easier to reason about where
does this metric come from.
- Group metrics by their modules, makes it easier to discover.
- Do not print the list immediately on command, do it later in the
frame. Makes it print correct latest frame values.
This makes water static for now, and also makes it look weird, e.g.:
- no culling of water sides (it is "dynamic" in a sense that it's an
entity property, not model property)
Make sure that things get created and destroyed at the right times.
Allow longer-than-map block allocations.
Fix brush model leaks -- previously they weren't destroyed on map
change/game exit properly. Also free geometry ranges accordingly.
Add a note about map loading process, and various models lifetimes.
The intent is to manage long-vs-single-frame allocations better.
Previously long allocations were map-long bump allocations, and couldn't be freed
mid-map, as there was neither a reference to the allocated range, nor a
way to actully free it.
Add a two-mode block allocator (similar to previous debuffer alloc) that
allows making long and once allocations. But now long allocations are
backed by "pool" allocator and return references to the range.
This commit doesn't do the deallocation yet, so map chaning doesn't yet
work.
