Blend files with a lot of Shape Keys aren't compressed efficiently

long term - could / should shape keys be converted into generic mesh attributes?

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.

EEVEE-Next: Viewport pixel size with up-scaling

I see we have flat scaling, will FSR / DLSS be in the cards at some point?

Geometry Nodes: Sample Grid Index node

using 'blur attribute' with this - would result in interpolation intentionally eh? or is this behavior impossible?

EEVEE-Next: Add normal layer reuse

Nice!

Could we get before / after metric for performance ?

Geometry Nodes: new Bake node

Was wondering, for quick playback - does this data live in a array on the gpu or is the geo still fed each frame to the gpu?

Geometry Nodes: Matrix socket type, attribute type, and initial nodes

In the future, perhaps matrix from input location, rotation and scale?
