[SOLVED] Is there a way to force material to shader compile?

[JCPalmer]

I am starting to use ShaderBuilder for some new 'grand entrances'.  That is when a mesh is instanced (after any textures have been loaded), it is accompanied with some kind of effect & sound.  My entrances till now have been assigning temp materials, scaling, or animating a shapekey.

ShaderBuilder is actually done against a temporary mesh.  A cylinder for Teleport entrance, and sphere for a Poof entrance.  I wanted to show the mesh & any kids when 85% of the animation is complete.  Problem is, if this is the first time permanent mesh is being made visible, there is a slight hesitation right in the middle of the shader builder animations.  It just kind of ruins it.

Works purrrrfect on subsequent entrances.  Is there something I can call on the permanent meshes before I start the animation, to make sure everything is ready?  I could do a quick show while mesh was at scale(0.0000001, 0.0000001, 0.0000001), but looking to find a crap-free method.

Ok, I find the effect / shader is actually defined in the call to a material.isReady().  Would calling this after I know the mesh geometry is complete, and all my texture completion callbacks have run be a way?  Node.isReady() does not really do anything.

mesh.material.isReady() also does not remove the short frame freeze.

Actually, setting the scaling incredibly small works good.  A little bit of a hack, but I was already hacking a bit.  QI was setup not to allow new queue items to start while mesh was not enabled.  I was enabling the mesh to get the queue to process events, but setting visibility to 0.  At 85% complete, was setting visibility back to 1.  Visibility does not apply to child meshes, unlike scaling, so had to get all the descendants & apply visibility both ways in loops.  Using scaling at just the mesh is still cleaner on a relative basis.
