I've been having trouble ever since 19.5 dropped.
When I want to show the Flowmap Visualizer, the Houdini Console gives me this error.

-------------
0(216) : error C3002: call to undefined function "void HOUassignOutputs(vec3, vec3, vec3, vec3, vec3, vec3, float, float, float, float, float, float, float, float, vec4, vec3, float, float, int, int);"
/obj/geo1/flowmap_visualize1/shopnet1/shop_flowmap_shader1: Linking failed.

I wrote about the same issue on Steam, someone made a report but I don't know what happened after.
I was also told someone did not have this issue after they installed the latest Nvidia studio drivers.

I have a RTX 4090, installed the latest studio drivers, version 528.24


I'm at a loss of what to do.

Please contact support so that this issue can be logged.

Done.

Still an issue. Crashes a lot while dealing with flowmaps. Extremely frustrating.
Am I the only one?

hi OLAHALDOR

I having the same issue did u find that solution for this error.

Same problem. I think shop_flowmap_shader broken.

Same thing, apparently still broken unfortunately after 6 months

Hello,

I'm having the same issue.

I hope it will be fixed soon.

Same issue here. Any update?

Adding “vec3 coat_color, float sheen_intensity, float sheen_rough, vec3 sheen_color”
into HOUassignOutputs after “coat_rough” can fix the issue.
