No shader refresh with pipe

I have curve with pipe activated


I select it, the color preview changes to the first affected material

I define a new material, the color don’t change

I unselect the pipe, the sahaer is refresh and correct

This effect does not always appear.
I don’t know the command conbinaison that produce this effect.
This effect appear in Shader, Render Mode, and in Cycle mode the material remains gray

For this file i have export the pipe with “export selected”, the bug persists.

But first change the material of pipe for produce the effect.

I found the reason.
The selected preview use the matérial of curve. The unselected preview use the material of pipe
This effect occurs only if you affect a material before activated the pipe option.
A extended effect is that all the pipe are affected when one pipe is selected


Is it useful to write on this forum?
Or we must post the bugs to another site?

Yes.

Here is the best place…
