Raytest inside simulation -> used to get hit_index -> sample attributes is not returning attributes

it never worked - I am just testing sim nodes for the first time in the last 2 weeks*

as for system info - how would that help? (this is a generic problem not like a driver / cpu issue)

Bump Map and Normal Map causes flat shading.

there is a 'strength' option for normal maps - when we bake the normal maps ideally 1 strength should correlate to the appearance of the map being correct.

if this is not the case either…

Cycles: new Microfacet-based Hair BSDF with elliptical cross-section support

maybe something using realtime raytracing can mimic this for EEVEE-Next?

Compositor: first steps to use realtime compositor outside viewport

so realtime comp / 2d filter nodes will be able to be ran vs a offscreen now?

nice ! 🥇

Compositor : improve Viewer node behavior

I think that having multiple viewers side by side active would be nice for debugging writing 2d filters in composition nodes / FX / AOV etc.

how far away from non-blocking render are we?

Rendering large scene causes viewport shading rendered to go out of memory

Ideally some sort of megatexture could be used, and all materials merged into a single material, this would reduce ram usage as well as GPU state changes*

in old bge I did this myself using…
