thanks sabine, you got me looking, adding this clamp has stopped the crashing to desktop.  i was lucky to make  a reproducible_crash.frag  so i could eliminate something with each fresh install.  It is a bit weird because there is a maximum in the palette6.frag,

This is the new code that stops my crashes, but I now realize it should be after the   >bailout check.

i still need to investigate further but I am much happier now. When I have fixed it up a bit more I will redo the previous frags on this post.

Have given the abox a good spin, no problems, very nice colouring behaviour in all examples!

Two very small suggestions

In DE-Raytracer_palette6.frag
PaletteStrength could benefit from being greater than one (more vivid colouring possible)
Code: [Select]
uniform float PaletteStrength; slider[0,1,10], does seem to do well in the mix...
SoftShadow-uniform needs to be set >0 for division in conditional QualityShadows (this needs to be changed in DE-Raytracer too, will alert 3Dickulus to it)
Code: [Select]
uniform float ShadowSoft; slider[0.000001,2.0,20]
and preset OrbitTrap2 moans a bit because startColorValue = is empty ;)

colorpalette6   changed this slide so cannot be zero  (possible /0 error), and reduced the maximum to suit the abox

Code: [Select]
uniform float ToolW; slider[0.0001,1.0,2.0]
stripped it down by removing commented_out code

I have removed all the old versions from this post
Abox/asurf in previous post is up to date.. It has original point color, single value orbitTrap color & spherical fold colorValues
Here is a menger sponge version. It has original point color, single value orbitTrap color & one colorValue from a formula condition

Color can be blended  from base color, old vec3 orbitTrap color and  the new code color.



TODO  other types of fractals, then later upgrade the palette frag, maybe insert it all into a de_raytracer frag
