Houdini 17 (both production and daily build) crashes upon opening preferences dialogue. Oddly enough, opening fairly complex scene doesn't seem to cause it to crash. This is what it says when it starts: k  /  opt  hfs17.0.396  X server found. dri2 connection failed! DRM_IOCTL_I915_GEM_APERTURE failed: Invalid argument Assuming 131072kB available aperture size.

That's what I was thinking about. It was more of a curiosity than an actual issue anyway. Cheers

Is there a way to tell mantra to always render one shader in front on the other when rendering co-planar surfaces ? Cheers

I might be wrong but as far as i know nothing comes close to splashtop in terms of speed and portability

Thanks a lot , that is exactly what I was looking for

I am trying to create an attrubute that would tell me whether point on the curve turns left or right, say 0 for left turn 1 for right. Any ideas ? cheers k

I used to use cinnamon after gnome disaster on ubuntu, looked great but crashed too often for my liking so I switched to i3 and will never go back to silly floating windows ever again. Needs a bit of reading through docs before you can use it effectively but it is totally worth it. Also 12.5 viewport seems to be less of an issue.

I am having following problem: I am trying to extract one line from text file using `system("sed '$F!d' /home/kumpa/test.txt")` and it works fine. As soon as I replace $F with expression (stamp() in my case) it returns bracing error. Any ideas ? cheers k

Extremely cool ! http://madeonjupiter.com/the-puffer-from-digi-to-real/

Speaking of speed streching, did anyone ever used that feature in particle fluid surface node with success ? I found it extremely useless so far.

Hi ! We are still hiring in case somebody is looking for job. cheers k

You can save takes and open them in another file, it even works with otl's you are using and updating all the time as long as parameter names stay same.

Thank you Jeff, you are superstar Changing coving settings didn't help but since i am not using any delay load I am ok with raytracing.And I am not rendering sds. I attached file as well Thanks k vine_06.hip.tar.gz

Any idea why this is happening ? Both images were rendered in render view using same rop, only difference was that preview box was ticked on on one without spikes. There is also completely different shading on trunk. There are no shadow maps and all shaders are mantra surface with bump map with exception of flowers that are shaded with clay (no displacement !). Version is 11.0.733. Sorry for huge images :/ cheers k
