Vulkan: Parallel shader compilation

How long until VK is usable you think? (Better than openGL?)

Merge doubles is breaking uv stored at face corners

"uv" are stored at the face corner domain.

when points are merged - the uv face corners they 'own' merge - not their values.

their is the same number of edge loops after this merge doubles…

Volumes: improve file cache and unloading

does this mean a user could play multiple copies of one cache in a blend file at different times ?

(like flickering volumetric stylized torch flames or something?)

this document includes numpy by default and is a good example, however its hard to read for newbs.

Regression: Terrible Eevee Performance compare to Blender 4.1

there is a setting to limit scale of shadow resolution - people have found this is the best way to gain back the FPS in upbge fork

Captured tangent are wrong when joined in a second object if curve has rotation

it looks to me like the rotation of the curve is not being taken into account in the final rotation,

when the 'join' happens - this data needs to transformed I suspect into object space of the…

Captured tangent are wrong when joined in a second object if curve has rotation

yeah its same in blender master - if I extrude each point using captured attribute inside the curve objects geometry nodes it works as expected

if I extrude each point using captured tangent…

I don't see any npr features that the composition system could not do, if it had "curvature" input as a channel we can turn on/off.

bvh.ray_cast function ignores object transforms on tested object of bvh

You need to transform your ray into local space.

loc, rot, sca = mat_out.decompose()

End = Obj.matrix_world.inverted() @ EndPoint Direction = rot.inverted() @ Direction

EEVEE-NEXT : Shadow are computed frame after frame and create a bumped, noisy non regular shadow during animation or camera moving.

I noted this stopped when TAA was off, (this was a while back) is it still the case?

EEVEE: Emission not received when Shader to RGB is connected

Perhaps you can use a aov for shader to RGb, and combine it with bdsf from main buffer using composition.
