Baking normal maps always crashes in blender v2.90 cycles. The same blender file opened in blender v2.83 cycles, where there is no crash baking the normal maps.

Have other users had a similar experience with blender crashing when baking normal maps in v2.9?

What additional steps are there required to avoid a crash?

my solution

install blender v2.91 experimental build as of 15_09_2020 installed not on c drive did not take set up from v2.90

additionally

make sure hires and low rez have render flag on if off fails set bake to an actual folder path not c\tmp prefarably not on c drive save as rgb 16 bit no alpha set samples to 1 1 make sure bake extrusion big size here 2m, but if overlapping geo smaller size.

create new texture for normal map alpha off 32 bit on,will save as 16 bit later assign mat to lowres, then image map load your new empty normal map button left set to non colour

DO NOT link up node till baked sel hirez geo then ctrl sel lowres geo, sel image map

BAKE used def tile size 32 32https://www.flickr.com/photos/93465359@N03/50343650117
