Both looking convincing, very nice. And thanks for the hint doing it with ICE. 
I will give it a try.

Implosia is a good bet. Remember to triangulate your geo before doing complex 
booleans - it will be a lot more stable.

Other than that, I know it might not help you, but the new boolean engine in 
Houdini 16 looks amazing:

The hard mesh tool is very interesting, it looks like it also plays nice 
with MESH inside Maya.

And a very reasonable price too.

thanks for the heads-up on this one :-)

Hi list,

I had several projects lately  that involved animated booleans with
CAD data, which is problematic sometimes. I used the old BoolTrace
shader by Alan Jones but it has its drawbacks: With many objects,
using different materials, it's hard to  keep track of the shaders.
Another problem was, that there is a limitation in the shader with
reflections. Let's say you have a box and a sphere and the box is
cutting the sphere in half. If another objects that is reflective,
intersects the cutting volume (the box) it will reflect the box by
it's primary rays. I assume that is because the shader interchanges
primary and secondary rays under the hood. I could potentially get it
solved by using passes/partition trickery or another shader to get
selective reflections on object basis. However, this becomes quite
complicated with a handful ob objects, all using different materials.

On some projects I switched back to real (geo) booleans and fixed the
"popping" of meshes by slighty adjusting the fcurves or cleaning the
topology a bit, but its a hack. On another project I got away with
slightly incorrect reflections using render time booleans. At the end
it worked somehow but it was almost never elegant or straight forward.

Is there an alternative to the (rather old) booltrace shader for XSI?
Anything for redshift in that area? Last, not least, how do you
approach animated booleans with complicated/heavy meshes nowadays?

Thanks,

Sven

Re: Animated booleans now and then

2017-08-29 Thread Morten Bartholdy 
Implosia is a good bet. Remember to triangulate your geo before doing complex 
booleans - it will be a lot more stable.

Other than that, I know it might not help you, but the new boolean engine in 
Houdini 16 looks amazing:

Also Maya has lately gotten a couple of boolean plugins that look promising, 
although I have no idea about stability:

Re: Animated booleans now and then

2017-08-29 Thread Jonathan Moore 
The Implosia booleans are great if you can manage to build a bug free
network but Implosia is definitely on the flaky side. I hate to say it but
Houdini is the best route forward. The new booleans in H16 are rock solid
and it's child's play managing the Redshift shading network (no extra
charge to use RS in Houdini).

Hello,

you can also try Implosia

Hi list,

I had several projects lately  that involved animated booleans with 
CAD data, which is problematic sometimes. I used the old BoolTrace 
shader by Alan Jones but it has its drawbacks: With many objects, 
using different materials, it's hard to  keep track of the shaders. 
Another problem was, that there is a limitation in the shader with 
reflections. Let's say you have a box and a sphere and the box is 
cutting the sphere in half. If another objects that is reflective, 
intersects the cutting volume (the box) it will reflect the box by 
it's primary rays. I assume that is because the shader interchanges 
primary and secondary rays under the hood. I could potentially get it 
solved by using passes/partition trickery or another shader to get 
selective reflections on object basis. However, this becomes quite 
complicated with a handful ob objects, all using different materials.


On some projects I switched back to real (geo) booleans and fixed the 
"popping" of meshes by slighty adjusting the fcurves or cleaning the 
topology a bit, but its a hack. On another project I got away with 
slightly incorrect reflections using render time booleans. At the end 
it worked somehow but it was almost never elegant or straight forward.


Is there an alternative to the (rather old) booltrace shader for XSI? 
Anything for redshift in that area? Last, not least, how do you 
approach animated booleans with complicated/heavy meshes nowadays?


Thanks,

Sven
