why my alembic procedural always crash during rendering arnold5.1

my custom alembic procedural can normaly render in arnold5.0,but can't in arnold5.1, i will show this

this node can render, each procedural node can render by itself, that means if the ass only have one procedural is ok

this case is also ok,but when i load two procedural node, it will crash

At the moment, I think that multiple nodes will not work,but

now,I found this problem may be the uv or normal

ERROR | [polymesh] JueLei_A_Render_AR_Shader_1Shape/JueLei_A_04_Model_H_Shader_Ar_Wind/JueLei_A_Render_AR_Shader_1Shape: incorrectly defined normals, missing either nlist or nidxs

but why this node can render by itself ????????

Which Mtoa are you using ? Arnold core 5.1 introduced a bug where render might crash when encountering invalid nodes from a procedural (ass, abc, xgen...). This was fixed 5.1.0.1 (mtoa-3.0.0.2).

I know this caused issue on our side where ASS working fine in 5.0 were now crashing with 5.1...

Can you try adding

enable_procedural_cache off 

or

parallel_node_init off

in the user options of the render settings?
