Yes the isosurfaces can be slow, but fortunately Chris's macros come with a
debug mode where it will just use a regular box{} with the same texture. It can
even give it a surface normal for the light shading - it's like the next-best
thing to a real isosurface.

Also I have found a good thing to do when using the plank macros is to render
one just by itself with a high max gradient (30+), then see what the parser
tells you the real max gradient was, at the end of the render. Then use a value
close to that, it should speed up the final render considerably.

Start with a very small roughness and only increase it if it doesn't look enough
after you render. If using the debug mode you will need approx. 2x the roughness
as for the same isosurface.

Remove the interior and reflection from your glass and water to speed up test
renders :)


Lots of random tips! I hope some of them can help.
